"Sunation installed solar panels for us 9 years ago which included installation of a lifetime roof. Several years ago squirrels gnawed on some of the wires. They were quick to repair and provided a solution to eliminate the problem. Our electric bills after installation are around $400 a year versus what I estimate with inflation would be $4,000 per year had we not installed the panels. Our 10,000 KWH system still produces about $12,000 KWH per year."

"In order to get my roof repaired, I had to get my solar panels taken down and replaced. Bright Light Energy Corp got the job done for $400 less than my original quote and began work the day after I contacted them. The first company had a 30-day wait. They are clearly professionals who know their business and provide a well-done service in the time and cost they quote. I highly recommend this company."

Solar Panels FAQs, answered by experts

You shouldn’t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

Solar panels can pay for themselves in five to 15 years, depending on the cost of your system, how much energy it generates, whether you qualify for incentives or power buybacks, and the price of energy in your area. Solar panels pay for themselves over time as they lower electricity bills, so it will take time to recoup your initial investment. However, the longer you have your system, the more money you can save and earn.

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.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.
