"I was referred to ExactSolar from a friend of mine who is extremely knowledgeable about the solar industry and he insisted that there was no better company in our area than ExactSolar. After meeting with and receiving quotes from four different companies, I decided that ExactSolar was the correct choice hands down. From the moment I contacted Dara, she has been nothing short of courteous, patient, knowledgeable, and extremely helpful in working with clients to determine the best solar system fit for each individual property. Dara and I started the process of planning my solar project in January 2020, and even through a pandemic, Dara was always quick to respond to an email, text, or answer a phone call for the many questions I posed throughout the entire process. Where other companies seemed to send mere salesman interested only in selling and doing so as quickly as possible, ExactSolar allows you the ability to deal with the actual owner (Dara Bortman) who patiently guided me in decision making from start to finish and set realistic expectations from the very beginning so I know exactly what I was going to get. On installation day, Nick and his team couldn't have been more friendly and professional. He kindly explained the process before, during, and after installation. ExactSolar is an honest and elite company with markedly impressive ownership and employees and are exceptionally highly recommended!! -BQ"

"Matt from Super Powered Solar arrived within the expected time frame. He took his time and answered all my questions before starting the job. He was able to to get to the solar panels on my two story home and replace the failed micro-inverter under one of the solar panels. He then came inside and helped me get the new micro-inverter activated with the company that supplied this replacement unit. He knew what he was doing and the job was completed to my satisfaction and the new unit is now working normally with the rest of the system."

"I contacted Solar Medix replace two DC string inverters on our 15 year old solar array. As it turned out, they were able to correct some wiring instead of replacing the inverters! Thank you for doing a fantastic job! They saved us a few thousand dollars! And I highly recommend them!"

Solar Panels FAQs, answered by experts

The average cost to install solar panels is around $27,000, with most homeowners paying between $4,500 and $54,000. These prices don’t consider the federal investment tax credit (ITC), which can reduce costs by up to 30%. The final price depends on several factors, including the size of the system needed to offset your energy consumption, the amount of sunlight your home receives, your geographical location, the type and brand of panels, labor costs, and any add-on products like solar batteries or electric vehicle (EV) chargers. It is recommended to get price quotes from at least three solar companies in your area to find the best deal.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.

No, you cannot turn on a new solar system before inspection. The inspector checks that the system is correctly connected to the grid and that safety components and features are in place. This process prevents problems on the electrical grid and offers protection against fire in your home. 

Your local utility company may also require inspection documentation before you can connect to the grid. An inspection can ensure solar power efficiency and determine how you might increase it.

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

For most U.S. homeowners, switching to solar energy is an excellent investment. A properly sized solar array can significantly reduce your electric bill, saving money on utilities every month. Most homeowners enjoy savings that cover the cost of their solar systems within 12 years and then turn a profit. Additionally, federal and state tax incentives are available that help make solar an even better and more profitable investment.
