Solar Myths & Facts
Common Solar Myths and Misconceptions
When it comes to installing solar panels on your roof, some homeowners may be hesitant to adopt it because of what they’ve heard or read on the internet. We live in an era of misinformation, which, unless we vigorously check our sources, can prevent us from living our best lives.
But fear not: The U.S. Department of Energy Solar Energy Technologies Office (SETO) is all about the facts. Let’s set the record straight so rumors and falsehoods don’t prevent you from reaping the benefits of solar energy. Here are some common myths and misconceptions:
Myth #1: Solar only works when the sun is shining. I still need power when it’s raining.
Actually, solar technology can be leveraged in virtually any condition, including rainy and snowy days, because some sunlight still reaches the earth. Solar panels tend to perform best in cold and sunny climates because heat interferes with the conversion of sunlight into electricity. (Keep in mind that solar panels collect light, not heat.) On top of that, battery storage can be connected to your solar panels and provide energy at night. This is your clean-energy backup, as opposed to conventional backup generators—if the power goes out in your neighborhood, your power will stay on.
But the bottom line is, unless you’re among the tiny fraction of Americans who live more than about a mile from a power line, a home with rooftop solar panels is still connected to the electric grid. This means that if your solar energy system doesn’t supply enough electricity, the grid will supply the rest.
Myth #2: Solar panels aren’t efficient enough.
Some customers hear that solar panels have an efficiency rate of 22% and wonder why it’s not 100%. Some sunlight will be reflected off the panel or be turned into heat instead of electricity. Solar cell materials also can’t absorb all the types of light that make up sunlight, like infrared light. The world-record efficiency for a solar cell at room temperature under normal sunlight is 39%, but these cells are too expensive to be cost-effective for home solar panels.
Truth is, the sun produces an enormous amount of energy—the sunlight that shines on the earth in just one and a half hours has more power than the world consumes in an entire year. With this huge energy supply, commercially available solar panels provide plenty of power to meet your home’s needs, at a cost at or below electricity provided by the grid in most parts of the country. But solar technology continues to advance and improve every year, thanks in part to research funded by SETO. If you wait for continued advancements, you may risk missing out on today’s plethora of solar incentives and tax credits, which come with expiration dates.
Myth #3: Solar is too expensive.
While the cost of a residential solar system can range from $15,000 to $35,000, you don’t have to pay for it all at the time of installation. There are several solar financing options that allow you to pay over time, plus local, state, and federal tax incentives and rebates to offset the costs. And solar panels require little ongoing maintenance—they are durable and reliable. If you live in a dusty environment, you may want to clean them once a year to maximize power output, but that’s about it. As demand for solar energy continues to grow, SETO is working to ensure the costs keep declining.
Myth #4: I don’t own my house, so I can’t go solar.
If you rent your house or live in an apartment building, community solar programs enable you to take advantage of solar energy. Community solar programs allow multiple people to benefit from a single, shared solar array. These arrays can be installed on your building or off-site. Purchasing costs and the installation of the solar energy system are then divided among all of the participants. Then everyone can buy into the shared system at a level that best fits their budget.
It can be challenging to make tough decisions about going solar with so much conflicting information floating around. Rest assured, the Solar Energy Technologies Office provides resources and trustworthy information.

What Out Clients Think Of Us…
I hired Mitchell Solar Solutions LLC after they did my roof. They mentioned that they also did solar installations as well and I decided to give them my business after the amazing job they did on my roof. I was astounded by the cost benefits from going solar. It’s a no brainer! After Chris sat down with me and explained the breakdown and how it has a return of over 20 years I said sign me up. The guys installed the entire system in one day and they walked me through all the operations as well. My system is finally live and my first electric bill was only $15 dollars! I am overwhelmed with excitement and can’t wait to see my return over the years to come. I definitely would recommend Mitchell Solar Solutions LLC to anyone who is ready to cut their electric bill into shreds!
Mitchell Solar Solutions just completed my solar system. They did an absolutely wonderful job the price was very reasonable compared to other companies and they also fit me in their schedule earlier then most. I would 100% recommend Mitchell Solar Solutions because they are very honest and do exactly what they say! I can not say enough about them!
