"Tim, the owner, came over to review what we needed. He ordered a new inverter, was very communicative and installed the new inverter once it was received. We could not be happier with the service Tim and Sunivation Solar provided for us, and we will not hesitate to call them back should we need anything again. Tim was extremely kind, very thorough and just did an excellent overall job. Thank you!!"

"My thermostat panel burned out. I was under warranty, fortunately. The panel was no longer being made so they replaced it with an upgraded thermostat panel at no cost. All I paid for was Labor. I have been using FourSeasons for many years and although they are a bit pricey, they are very professional and always get the job done. They also replaced the Circuit board on my furnace at no cost."

"They were very knowledgeable and through. I had sat down with several solar companies and Illinois Solar Power not only beat their bids but they helped me understand what type of system was best suited for my home. They had multiple options. I chose to go with owning the panels for no upfront cost and am extremely happy."

Solar Panels FAQs, answered by experts

Solar shingles and solar panels are not the same. While solar shingles use the same technology as traditional solar panels, they integrate with your existing roof. That means they are used to build your roof instead of simply resting on top of it. When comparing solar shingles and solar panels, it's helpful to know that solar shingles are more aesthetically pleasing than solar roof panels. They also do better in harsh weather due to limited uplift from strong winds.

In almost every case, solar panels need to be removed to replace roof shingles. In some cases, such as solar installations where the panels are on raised platforms above the roof surface, installers may be able to install new shingles without removing the solar installation. However, to get a quality roofing installation, panels need to come off. Most roofing contractors won’t remove or reinstall solar panels as part of a roofing project, so you’ll need to contact your solar provider.

Yes, a solar panel can power a TV without a battery, but only if the sun is shining and the panel is generating enough energy. Your solar panel and TV must have the same voltage, and you should install a charge controller and inverter between them so power surges don’t destroy your TV. To watch TV at night, in the early morning and late afternoon, and on cloudy days, your home must be tied to the power grid.

Homeowners replace their solar panels after 25 years. That said, you don’t necessarily need to replace them at the 25-year mark. You’ll notice a declining ability to produce electricity over time. Most homeowners spring for a replacement when they notice their energy bills creeping up to regular levels or when solar panel repairs are extensive, frequent, and no longer economical.

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.
