"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

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.

The best solar panels to withstand hail are those rated UL 61730. These solar panels are certified to withstand hailstones up to 3 inches in diameter and travel at speeds up to 88 mph. IP68 solar panels are the next most resilient solar panel. Solar panels without these ratings can handle hail up to 1 inch in diameter that travels up to 50 miles per hour. If you live in an area with frequent or severe hailstorms, purchasing UL 61730 solar panels is often worth the investment.

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.

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.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.
