"Unfortunately my husband s company is moving us to the midwest. Even though we had a signed contract with Rick and Teresa at Sunriver Solar, they we very understanding and basically told us not to worry about it and to enjoy our next adventure. They even asked if they could help us with any of the moving stuff!!! They are a delight to work with, they do everything, they kept us up to date on what was going on, and, even though we could not work with them, we would highly recommend them. You really cannot go wrong with Sunriver Solar."

"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Working with the ILUM Solar team was a true pleasure. We started our project on our own and quickly realized we needed some help. I contacted ILUM Solar and Robert Dean took over the planning, permitting and installation process. We have had our ground mount 60 panel solar system for 3 years with no problems. Highly recommend."

Solar Panels FAQs, answered by experts

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

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 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.

Removing solar panels can be straightforward, but it’s not necessarily a simple process. Your contractor needs to prevent damage—not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you’ll need to hire a licensed electrician to disconnect it.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.
