Do Solar Panels Increase The Value of Your Home?

People decide to install a solar system in their homes for a number of different reasons.

Some folks are looking to switch to a renewable form of energy, so they’re not depleting the earth’s finite resources every time they switch on a light. Others are concerned about the disastrous environmental impact coal-burning plants have on our land, air, and water.

Some turn to clean green energy out of concern for the present, whereas others are trying to preserve the planet for future generations.

And, of course, a lot of folks go solar simply because they’re tired of paying exorbitant monthly energy bills.

But another financial benefit of installing a solar system is that it will increase the market value of your home itself. And that’s not just conjecture, researchers have been quantifying the beneficial effects solar panels have on market-value for decades.


Energy Savings in Homes

Way back in 1983, a couple of researchers named Ruth Johnson and David Kaserman found that home value increased by around $20.73 for each dollar saved annually on energy. According to the U.S. Energy Information Agency, the average family in Pennsylvania spent around $1400 on electricity in 2019. If Johnson and Kaserman’s numbers still hold up, that translates into an increase in value of $29,000 for the average PA homeowner who  goes fully solar with a host-owned system.


The Market Value Establishes

A more recent 2011 study by the National Bureau of Economic Research (NBER) found that buyers are willing to pay around 3% to 4% more on average for homes powered by solar energy. Moreover, the NBEC found that this increase exceeds the amount of money buyers will save by generating free electricity. Merely having solar panels, itself will increase the value of your home somewhat even if you lease them. As the NBER report notes:

Similar to other home investments such as a new kitchen, solar installation bundles both investment value and consumption value. Some households may take pride in knowing that they are producers of “green” electricity and “warm glow” may triumph over present discounted value calculations in determining a household’s install choice.


The Market Value Increases

A 2015 study by the Lawrence Berkeley National Laboratory tabulated increases in home market value in terms of the size of its solar system. For every kilowatt (KW), the value of a home with a host-owned solar system increased by around $4000. Hence, a small solar system of around 5 KW owned outright would yield a $20,000 increase in market value, and a larger 20 KW system would yield around $80,000 extra when it’s sold. 


 The Importance of Solar Homes

Finally, a 2019 study by the real estate marketing website, Zillow, found that around 90% of home buyers say energy-efficiency is an important factor, with 56% labeling it extremely important. And there’s no way to be more energy efficient than harnessing the power of the sun to generate your own cost-free electricity.


The Different Factors of Solar That Effects Value

The exact amount of added value you’ll get by installing a solar system will, of course, depend on a number of factors.

If you lease your solar system instead of owning it, the increase in home value will be significantly less.

Other factors influencing just how much added market value you’ll get from going solar include the cost of electricity in your area and the amount of energy your system generates. Or, in other words, how much money you’ll save by reducing or outright eliminating your home energy expenses. To get a rough idea of the savings you can expect, you can check out Google’s Project Sunroof.

But, if you’d like a more precise idea of how much money you can save by going solar, call for an appointment with one of our design consultants and get a full no-obligation analysis on:

  • The exact solar system that’s appropriate for your roof.
  • How much energy it will generate given local weather, trees, and other obstructions.
  • And importantly, exactly how much money you can expect to  save on monthly energy by owning the system vs. leasing it.

The bottom line is that the higher that number is, the more added market value going solar will bring to your home.

Why It’s Essential to Have Professionals Install Your Solar Panels

Considering the many reasons to go solar, a homeowner can earn some excellent advantages when installing solar panels. You’ll go green and give back to the planet, and you may also generate enough extra energy to sell back to your utility provider. 

If you’re considering making the switch, you should know one of the most critical parts of the process is deciding who to hire. A licensed, seasoned professional can make the difference between an energy-efficient, high-yield system and one that doesn’t work as it should. Learn about the benefits of picking the right installation service and how to compare solar companies the right way.

The Benefits of Working With Seasoned Solar Professionals

More than four in 10 homeowners are considering solar panels for their homes. Many of these property owners overlook the importance of professional installation. They may try to save some money by going with the company that offers the lowest quote or even attempt a DIY installation.

Choosing a skilled professional offers you many advantages, and the extra costs don’t add up to much more than you’d pay for a cheaper option. Since you’ll realize fantastic savings over your current energy bill, it makes sense to invest a bit more in a professional service that will help you gain the maximum energy yield and benefits from your solar panel system. Consider the following factors.

1. The Panels’ Quality

Not all solar panels and related equipment are the same. Panels with different technology and quality have varying efficiency levels. Most rooftop solar panels peak at 18% efficiency, with some only reaching 11% efficiency. Choosing the wrong type could limit your energy production capacity.

Your equipment could also have a shorter life span, which may affect your ability to gain cost savings from solar. If your panels give out before you’ve saved enough money on energy bills to cover materials and installation, you lose any potential DIY installation benefits. 

When you work with a trustworthy professional, you get their expertise and time-tested materials. Professional solar installers know which products hold up for their customers because they’re the ones who get the call if something doesn’t work. They can recommend and install the panels that will work best and provide the most efficiency. 

At ReNu Solar, our panels offer the latest in solar technology. The secret is advancements like split cells and microinverters. They produce more energy, even when the panels have partial shade cover. The cell advancements let you gain a higher energy yield per panel. The microinverters keep the cells generating energy, even in 50% shade. 

2. Curb Appeal

As solar power becomes a more realistic option for homeowners everywhere, you may notice some solar panels look different from others. Aesthetics is an essential factor in choosing the best solar panels for your home. Many communities object to solar panels because they have a reputation for being eyesores. Indeed, many of the solar panels you’re used to, especially older designs, include visible white backings. Some have a bluish shimmer, which leaves a stark contrast with the roofs. However, even black panels with white backing will stand out.

The most attractive option, which is also newer technology, are panels with a black frame and black backing. Black-on-black panels are sleek and low-profile, so they’ll blend into your roof better. They’re silicon and have an anti-reflective coating, which improves energy output and makes the panels more attractive. Plus, with professional system design and quality installation, any wiring or other hardware stays out of sight.

3. Safe and Correct Installation

Unless you’re an electrician, DIY solar can become a pretty confusing job. First, many of the DIY solar kits available on the market don’t connect with the grid. Instead, they’re for small, off-grid applications, like sheds or recreational vehicles. That isn’t how roof solar panels work.

It surprises some people that installing solar panels on your roof won’t directly power the home. Instead, you’ll be selling 100% of the power you generate back to the utility company, which offsets your energy bill. An off-the-grid solar installation doesn’t let you earn credits from the utility company. You need lots of technical skills to safely wire the system to the power grid, beyond many DIYers’ abilities.

Besides the panels themselves, solar installations also involve setting up inverters, batteries and meters. Even if you go the DIY route, you need a licensed electrical contractor to sign off on everything. Professional installers have been in the business for years and have all the certifications required to perform safe solar and electrical work in your area. You can’t gain that kind of hands-on experience with even the best video tutorials.

4. Time Savings

Besides the installation itself, installing solar panels can be an involved, timely process. When you do it on your own, you must design your structure, navigate permitting in your town and discuss the job with your utility company. At ReNu, we take all the hassle and time out of switching to solar power. As solar installers in Pennsylvania, we’re familiar with your county and city permitting processes and fee structures. We’ll pull all the necessary paperwork and make your system compliant. 

We also correspond with the utility companies, which are notoriously slow to respond to requests. We have a team dedicated to planning solar installations and net metering with the utility company, and our established relationship speeds up the process.

Finally, we’re experts in the financing and tax incentives available to Pennsylvania residents for solar panels. We’ll help you find a loan for your project, so you pay less than your current monthly energy bill. Plus, we take all the steps needed for you to realize your maximum solar tax breaks and incentives.

5. Cost Savings

One of the top reasons homeowners go with a less-qualified professional or a DIY solar kit is the perceived cost savings. While you’ll save on labor, you could pay for it if the installation is incorrect or your panels break prematurely.

Many solar panel manufacturers only honor their warranties on products that had an approved installer. Trustworthy professional installers also offer a workmanship warranty. In our case, we back our handiwork for 25 years. You can trust your panels to hold up for years to come, which saves you money on repairs or calling a pro to salvage a DIY installation.

Professional installation companies also offer strategies to help homeowners save money without having to climb their roofs themselves. Here at ReNu, we’ll help you navigate tax benefits and selling solar energy to the utility company for energy credits. We also offer money-saving purchasing options, including our no-money-down ownership program.

  1. Best Placement for Maximum Efficiency

Solar placement is an exact science. Professionals use advanced solar technology to determine the best placement for maximum solar output.

Things to Consider When Hiring a Solar Installer

Once you realize the benefits of working with an experienced solar panel installer, the next step is to compare companies. What should you think about when hiring a solar panel installation company? Here are a few things to evaluate.

  • Roofing capabilities: Your solar panels’ integrity relies on a sound roof. Many homeowners need to upgrade their roof before it’s ready to hold solar panels. That’s why it’s smart to hire a solar company that also provides roofing services. Companies like ReNu will work a roof inspection into your initial consultation and take care of any repairs or replacements needed, all in one affordable package. ReNu offers an excellent roof-solar combo option, ensuring a watertight roof and a solid foundation for your new panels.
  • Experience and expertise: When evaluating solar panel installers in your area, check out their experience and technical know-how. When a technician comes over for an in-home estimate, ask about their years in the business, state certifications and licenses and any other relevant expertise.
  • Customer satisfaction: Gauge each solar company’s reliability by their customer reviews. Check out the testimonials listed on their website, alongside the reviews left around the web. Their average star rating is an excellent overall indicator, and a deeper dive into the comments will give you a sense of the kinds of people you’d be working with.

How to Save Energy When Working From Home

More people are working from home than ever. In fact, with the current state of affairs, nearly 42% of the U.S. labor force has vacated their businesses and are now doing their jobs remotely. With that incredible flexibility comes one pitfall — energy use. Previously, for eight hours a day, your house stood empty. Zero people meant very limited energy usage. Thankfully, there are a few ways you can stay efficient even while working from home.

5 Energy Saving Tips When Working From Home

If you’re looking to keep your energy bill under control even while working from home, here are five tips for conserving energy and saving money.

1. Stay in One Place

As you roam from one room to another, you undoubtedly flip on light switches, turn on TVs and use other electronic devices. Instead, having one dedicated workspace during your working hours can help limit the power you use in otherwise empty rooms.

2. Turn Off Lights

Natural light is a beautiful thing — and a useful thing. Instead of relying on overhead lighting, take advantage of your windows during the day.

Once the sun begins to set, you still don’t need to use energy-sucking overhead lighting. Task lighting or a small desk lamp should be sufficient when you’re busy at work. Be sure to turn the lights off when you leave a room, too.

3. Keep Your Thermostat Off When Possible

Your HVAC uses the most energy in your home by far, especially for those with electric heat. If you can turn it off while you’re working, you can save yourself a lot of money on your energy bill. During the winter, open up the shades or blinds in your home. Letting the sun in is a natural way to warm your rooms and limit how much you need to turn up the heat. In summer, you’ll need to take the opposite approach. Keep your shades drawn to keep the whole house a bit cooler.

4. Close Doors During the Day

Previous to working from home, you were able to adjust the thermostat more during the day since no one would be home. You can mimic this by closing doors and shutting air vents to rooms that are not in use during the day.

5. Avoid Leaving Your Devices Charging

Depleting the battery on all your devices is not a bad thing. In fact, cycling the battery on your laptop, cell phone and other electronic devices is good for them. Keeping your electronics plugged in when they’re fully charged sucks unnecessary energy and reduces their battery life. Pay attention and unplug devices once they’ve reached their maximum charge level.

Another tip is to unplug devices that you only use occasionally. This could include printers, scanners and even your small kitchen appliances.

6. Invest in Solar Panels

If remote work is your status quo, that means that your home is now your residence and your business. Now is the perfect time to make your home more energy-efficient. Solar panels from ReNu Solar are a simple, environmentally friendly way to save money on your monthly energy bill.

The cost of electricity will continue to rise each year. Solar panels are a smart investment that gives you a clean, renewable energy source that you can rely on day after day — year after year. The ReNu Solar Program actually allows you to earn money from the electric company via net metering. You can go green and save green at the same time.

At ReNu Solar, we handle everything from financing and installation to support after activation. Contact us today to learn whether your home is a good candidate for solar.

Saving The Environment with Solar

How Do Solar Panels Help The Environment?

Everyone knows that switching to solar energy is an environmentally beneficial way to reduce or even completely eliminate your monthly electric bill.  But you may be surprised to learn just how environmentally friendly going solar turns out to be.


Saving The Air We Breathe

The most obvious benefit of generating your own power from sunlight is the reduction in greenhouse gases and other pollutants that conventional power plants relentlessly spew into our air.

Not just burning, but even mining fossil fuels is an inherently destructive process that releases carbon dioxide, nitrous oxide, and methane into the earth’s atmosphere. Besides contributing to climate change, when we disrupt and poison the balance of gases nature intended us to breathe, we pay the price by suffering more respiratory illnesses, like asthma and even cancer.

Generating solar energy, on the other hand, is purely productive. It emits no harmful gases to disrupt the atmosphere’s natural equilibrium or harm our children’s still developing lungs.


Saving The Water We Drink

One of the Power Plant Industry’s best kept, dirty, not so little, secrets is that, besides the toxins and greenhouses gases emitted into our air, they’re also the biggest polluters of our water supply as well. 

A 2013 study by the EPA found that power plants dump more toxins like mercury, arsenic, and lead into our waterways than all of the next nine industries combined! These heavy metals act like neurotoxins. They can disrupt normal development in children, harm babies in the womb, damage everyone’s internal organs, and even cause cancer.

The worst part is that, instead of degrading, heavy metals accumulate. So, we can’t keep using power sources that dump them into the earth’s water supply indefinitely without eventually dumping them into our own. Even for the limited time we can keep them out of our drinking water, they still wind up impacting us by traveling up the food chain and accumulating in our bodies.

Solar panels, on the other hand, generate electricity without using water at all. You don’t have to pollute the earth’s water with dangerous toxins whenever you make a smoothie or turn on a light.


Saving Our Land

But industrial power plants don’t just pollute our air and water. They’re a triple threat – emphasis on threat. Coal-fired plants produce millions of tons of solid toxic waste every year as well. It gets quietly dumped into abandoned mines, landfills, and other places where it destroys fragile ecosystems and can be hazardous to nearby residents. 

There’s only a finite amount of space on the planet. If we don’t switch to renewable energy sources like solar, eventually the toxic sludge produced by power plants is going to wind up in all our backyards.


Saving The Planet’s Natural Resources 

Because industrial power plants produce energy through essentially destructive processes, they aren’t renewable sources of energy. Elements gradually formed in the earth’s crust over the course of its four and a half billion-year life are, in an instant, irrevocably destroyed. 

The productive nature of solar power, on the other hand, makes it not just a clean energy source, but a 100% renewable one as well.


Saving Our Climate

The U.S. Energy Information Administration estimates that in 2018 electrical power plants produced 1,763 million metric tons of the greenhouse gas carbon dioxide. That accounts for a staggering 33% of total U.S. emissions!

That’s why a recent study from scientists at the University of California published in Nature concluded that keeping global warming out of catastrophic range will require, not just building no new power plants, but also shutting down old ones. 

If we want to preserve the planet for future generations and keep present ones healthy, weaning ourselves from toxic and destructive non-renewable energy sources will be crucial. 

Switching to solar energy is a way each one of us can make our own contribution.

How Solar Power Is Created

The Power You Need

The electricity powering your home is a flow of electrical charge created by the movement of tiny negatively charged subatomic particles called electrons. Though it’s often claimed that electrical current is composed of the electrons themselves, this isn’t really true.

Your appliances run on AC or alternating current, meaning the flow of electrical charge is constantly switching directions. AC current in the U.S. switches back and forth a remarkable 60 times every second. That’s so fast that the electrons in your wiring never even get a chance to flow in either direction and wind up simply vibrating back and forth instead. But their back-and-forth vibrations do, nonetheless, cause an alternating current of electrical charge to flow through your outlets.

One factor complicating solar power systems is that the panels themselves don’t produce the AC current you need. Instead, they generate DC or direct current, which flows continuously in just one direction. So, in addition to panels, devices called inverters are necessary to convert the panels’ DC output into the alternating current required to run your appliances. 

Because the flow of electrical charge in DC current never changes direction, the electrons aren’t stuck in place vibrating like they are in AC. Instead, they flow in the same direction as the electrical charge they carry – albeit at a much slower rate. 

Turning sunshine into cost-free electrical power became possible when scientists and engineers developed efficient two-sided solar cells. When exposed to sunlight, these miraculous wafers generate a continuous flow of electrons through a wire running out of the top side, to your inverters which convert the DC current to AC for you to use or sell, and back to the bottom side. 


Electrons & Photons 

Electrical wiring conducts electricity because it’s composed of metals like copper containing relatively free electrons that aren’t bound too tightly to any particular molecule. So, when a force that pushes electrons is applied to one end of a copper wire, even if it’s relatively weak, it can break some electrons in the copper completely free and cause them to flow through the wire like a pump pushing water through a pipe. Plastic and other poor conductors are like permanently frozen pipes – all their electrons are bound tightly and, hence, “frozen” in place. So, it takes massive amounts of electrical force, or voltage, to get the electrons in plastic to move at all.

Generating solar power is possible because light is composed of incredibly small particles called photons that can interact with electrons. If the photons in a beam of light striking a metal surface have enough energy, any electrons they impact not bound too tightly to their molecules will be “knocked” free. Some will even be “knocked” off and emitted from the metal’s surface. Albert Einstein was awarded his Nobel prize for explaining this scientific phenomenon, known as the Photoelectric Effect.

But it’s also possible to channel the Photoelectric Effect into another scientific process called the Photovoltaic Effect. That’s when electrons impacted by sufficiently energized photons of light, instead of being randomly knocked around, get channeled into wires by an electric force, creating DC electrical current.


Generating Solar Power

That’s how solar power is generated. A solar panel is constructed out of several dozen wafer-like solar cells each composed of two different types of material: 

  • A negatively charged top layer that contains extra electrons. 
  • And a positively charged bottom layer that is missing electrons and, hence, attracts the extra electrons in the top layer.

The attraction between the top and bottom layers of a solar cell creates an electric field between them. The electric field in turn exerts an electrical force. So, when an electron in a solar cell is knocked free by a photon of light, it’s channeled toward a wire running from the top layer of the solar panel, to your inverters, and back to the bottom layer. When enough electrons are knocked free by sunlight, voilà! A flow of electrons producing DC current is created.

Next time, we’ll talk more about how the two kinds of materials composing solar cells create the force that channels electrons freed from their molecular bonds by the sun into free and clean electrical power.

AC vs. DC & Solar Power

AC vs. DC and Solar Power


Creating free electrical power from the sun’s rays requires more than just solar panels. Devices called inverters are necessary to convert the DC current produced by your panels into the AC current your home runs on. But a very small quantity of energy is lost in the process. So, when shopping for a solar system, make sure the energy production estimates you’re getting from different providers are all based on the same kind of current. 

For comparison purposes it doesn’t matter which. But it makes sense to look at estimates based on the AC power the inverters are sending into your home rather than the DC power initially generated by your solar panels. That way, you get a more accurate idea of your electric bill offset.

But why don’t solar panels themselves automatically produce the kind of power you need?

Electricity Isn’t Really Electrons

AC stands for Alternating Current.
DC stands for Direct Current. 

Strictly speaking, mentioning AC or DC “current” is redundant since it’s already meant by the “C”.  But like “SAT test” and “PIN number,” acronyms sometimes become so common that we stop thinking of them as such. It then seems funny not to redundantly throw in that already included last word when it helps to explain the concept being abbreviated.

Just like a current of water, an electrical current is something that flows in a certain direction. But the kind of current that flows through wires is composed of an electrical charge  carried by electrons in motion. You’ve probably heard people say that electricity is composed of the electrons themselves. That common explanation does make it easy to visualize electric current. But, in reality, alternating current actually prevents the electrons themselves from flowing.

Alternating Current gets its name because the direction in which it flows is constantly alternating back and forth. The AC powering your appliances changes directions an amazing 60 times every second. That rapid oscillation never even gives the electrons a chance to start flowing and they wind up vibrating instead. But the vibrations do, nonetheless, cause current or electrical charge to flow in alternating directions.

Direct Current, by contrast, continually flows in one direction. Its name can be a little misleading since DC isn’t really any more direct than AC. But, in direct current, the electrons themselves do flow with the electrical charge.

Why AC Became Standard

Around 200 years ago, scientists discovered an efficient way to generate electricity using a spinning magnet. But, instead of direct current, it produced current that alternated direction with the magnet’s rotation. Since there wasn’t any practical use for alternating current, early alternators usually had devices which converted their output to DC. Automobiles today still use an alternator to efficiently generate AC power, which is then converted to DC for battery storage.

When the invention of the electric light bulb created a demand for electric lines running into our homes, however, alternating current turned out to have one very big safety advantage. Transmitting electricity over distances much more than a mile requires dangerously high voltage to minimize the amount lost from electrical resistance. But lowering the voltage of direct current so it was safe to run into people’s homes was technologically unfeasible. As a result, DC power plants had to be very close to their customers. Besides all the inconvenience and inefficiency, generating DC power at a reasonable cost for sparsely populated regions was impossible since each plant could only serve a few homes at most.

Around 1886, however, William Stanley* invented a commercially viable device for transforming high voltage alternating current into a safer lower voltage. That meant that large scale power plants could provide high voltage AC power to customers many miles away and Stanley’s transformers could then be used to lower the voltage to a safe level before bringing it into their homes.  AC power pretty quickly became the norm and manufacturers stopped producing DC appliances.

The way solar panels generate energy from sunshine produces DC power. Nowadays, we actually have the technology to easily transform DC power to low voltage too. If it had existed 200 years ago, all the appliances in your home would run on direct current and we wouldn’t need to use inverters or accept the very small lose in energy production.

Thankfully, since solar power is a completely clean and 100% renewable resource, there’s always more sun to make up the small difference. And we don’t have to worry about damaging the environment by doing so.

*Though Nikola Tesla invented the AC motor and helped refine other technology important to making alternating current the dominant technology, he did not invent the transformer as is commonly claimed.

Albert Einstein & The Science of Solar Power

Albert Einstein is famous for revolutionizing physics with his Theory of Relativity. But did you know Einstein also discovered the science behind the solar technology now revolutionizing the way we produce energy?

In fact, Einstein was awarded his Nobel Prize, not for his famous equation E=MC2, but for the groundbreaking theory of light he developed to explain something called the Photoelectric Effect.

And the Photoelectric Effect just so happens to be the scientific process that makes it possible to turn sunshine into a cost-free, clean, and renewable source of energy. 


A Mysterious Novelty

Though it literally took an Einstein to explain the science of solar power, the sun’s capacity to generate electricity was discovered by a mere teenager forty years before Albert was even born! In 1839, a 19-year-old French researcher named Edmond Becquerel exposed a conducting solution containing metal electrodes to sunlight. For some strange reason, a small electric current was produced.

Fascinating as it was, no one could explain how Becquerel’s apparatus worked and it produced too little energy to be anything more than an interesting novelty. 

Scientists didn’t get a glimmer into the underlying process until almost 50 years later when, in 1887, a physicist named Heinrich Hertz discovered the Photoelectric Effect. 

But Hertz’s findings turned out to be as disturbing as they were enlightening.


The Photoelectric Effect

Hertz discovered that when a metal surface is exposed to light of a high enough frequency, it emits electrons that are “knocked” free from the atoms they orbit by the light’s energy. Until Einstein came along, however, no one could make any sense of what sometimes happened when Hertz altered the experimental conditions.

The theory then accepted as settled science was that light travelled as a continuous electromagnetic wave. So, because the light’s energy was transmitted in an uninterrupted flow, even if its frequency was just a little too low to immediately break any electrons free, increasing the light’s intensity or the amount of time it struck the metal ought to yield the slight energy boost required to do the job without upping its frequency.

The problem was that neither the intensity of the light nor the length of time the metal was exposed mattered. If the light was above a certain frequency, electrons were emitted as soon as it struck the metal. But, if the frequency was even the smallest fraction too low, no matter how long you exposed the metal or how much more intense you made the light, for some reason you could never accumulate the little bit of extra energy needed to break even a single electron free.


Einstein Discovers Photons

In 1905, Einstein shattered scientific consensus by showing that Hertz’s data meant light isn’t simply a continuous wave. Instead, though it resembles a wave in certain respects, light is composed of a series of separate moving particles called photons. 

When light strikes  a metal surface, the energy carried by the first photon impacting an electron is either sufficient to knock it free or not. If it is, the electron is emitted from the metal surface immediately. But only one photon can impact an electron at a time. So, if the energy in that first photon is even slightly below the amount required to free the electron, hitting it with another photon won’t help unless you give it enough energy to free the electron all by itself by upping light’s frequency.

Increasing the light’s intensity just meant that more photons each with too little energy to knock the electron free would be hitting it in a given period of time. Letting the light strike the metal for a longer period of time would likewise only increase the number of insufficiently energized photons uselessly striking the electron.

Einstein showed that light was both a wave and a particle and, importantly, the complex mathematical relation between its frequency  (as a wave) and the amount of energy carried by its photons (as a particle). 

The precise scientific understanding Einstein gave us eventually helped engineers design the solar panels that more and more people are using every day. They maximize and efficiently channel the energy produced by the Photoelectric Effect, creating a clean, renewable, and cost-free source of energy for your home.

Next time, we’ll talk about how today’s solar panels are designed to achieve those benefits.

Benefits of Solar


Make now the time you embrace the benefits of solar energy. Around the world, so many people and businesses have begun to adopt solar power that for the last decade, each year has seen an increase in power output from solar of 40%. Solar power offers you numerous benefits for your home, your wallet and the planet. By installing solar panels, your home increases in value, your energy bills decrease and the world benefits from more people using an emission-free energy source.


Is Solar Worth The Investment?

If you cannot decide if solar power is worth the investment, the answer is likely yes. At ReNu Solar, we can make it affordable for anyone to have solar panels on their home. Learn more about the numerous benefits of installing solar panels you can enjoy.


1. It’s Environmentally Friendly
As a clean energy source, solar power does not use polluting fossil fuels. Additionally, fossil fuels have a limited supply, whereas the sun provides power for everyone who uses it without limits. Sunny days or cloudy days continue to produce electricity from solar panels. While sunny days generate the most power, overcast days will still yield 10% to 20% of the energy a cloudless day can. Installing solar panels on your home has a significant impact on the environment by reducing carbon emissions and pollution that other forms of electricity produce.

Switching to solar energy can have a significant positive impact on the environment. For a home that uses 8,280 kWh of energy annually, generating electricity with solar panels reduces emissions by as much as planting 150 trees. Even a house that only uses 6,864 kWh each year can eliminate carbon emissions equal to burning 5,000 pounds of coal by installing solar panels.

2. You’ll Save Money
Today, solar power has become even cheaper than ever to install. Early in the 2000s, installing solar cost $10 per watt, but by 2013, the price had dropped to below $4 per watt. Today, prices for solar installation continue to fall.

Here’s how solar energy works with your energy bills. The power generated by your solar panels is automatically sold back to the power company. The utility sends you a credit for the amount you sell to them. Though you will still have a power bill and a loan for the solar panel installation, the amount you get back from the power company may cover both bills. Even if it does not fully cover both costs, you will still spend less on your electricity each month.

3. The No Cost Program Makes It Affordable
When you choose ReNu, we work with you to find a solar panel loan that costs less than your current power bill. In doing so, you do not pay anything extra to have us install solar panels on your home. While we don’t finance, we can help you find the best loan for your solar installation.

4. You Can Take Advantage of Solar Tax Credits
According to the state’s Public Utility Commission, Pennsylvania does not have a specific solar tax credit, but you can get one at the federal level. The Solar Investment Tax Credit, ITC, allows you to take a dollar-for-dollar discount on the federal income taxes that you owe based on a percentage of what you pay for solar panels. The amount of credit you can take will decrease over the coming years, so the sooner you install your solar panels, the higher a percent of your investment you can take off your taxes.

For projects that start in 2019, you can take off 30%. In 2020, the amount decreases to 26%, and in 2021 the percentage becomes 22%. After that, the residential tax credit disappears. There is no better time than now to invest in solar to take advantage of the most significant tax credits and to spend the least on installation.

5. Your Home’s Value Will Increase
Installing solar panels can increase your home’s value. The average solar array can raise your home’s selling price by $15,000. Additionally, upgrading to solar panels may make your home more desirable on the market, so you will have an easier time when you need to sell your home.

6. You Can Break the Chains of Energy Companies
One of the solar benefits in Pennsylvania is the ability to break out of the cycle of rising rates. In July 2019, Pennsylvania residents paid an average of 13.79 cents per kilowatt-hour for electricity. This rate is higher than in many other parts of the country.

With solar energy, you can break free from these changing rates by getting the energy companies to pay you for the power you provide them with your solar panels. You will significantly reduce or even eliminate the net amount you spend on electricity each month.

7. The Solar Installation Process Is Easy
The solar installation process is easier than you think. We take care of all the paperwork, permits and design to ensure you get quality solar panels with the least amount of hassle. Since we also help to source the best loan for your solar, you don’t have to worry about financing either.

8. Solar Systems Are Low Maintenance
Solar panels require little maintenance to continue to produce power. Even if you have snowfall, the snow generally melts quickly enough that it doesn’t impede power production from the panels. If your solar panels have a 15-degree angle or steeper, they will be self-cleaning, so you won’t have to worry about snow.

9. Net Metering Increases Your Capabilities
Through net metering, you sell the power your solar panels produce to the electric company. The amount you generate creates credits for your power bills. If your solar panels produce more electricity than you use in a month, the extra credits roll over to the following month. This rollover continues until the end of the year. If you still have credits at the end of the AEC billing year, you get a check.

In addition, in Pennsylvania, electric utilities must obtain a certain portion of their power from alternative energy, which includes solar. Instead of building solar facilities, utilities can purchase alternative energy credits, or AECs. If your solar system qualifies for the program, for every 1,000 kWh it produces, you earn an AEC. You can then sell this AEC, which can help you finance your solar system.
