"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."

"Not a single thing that I could complain about. Very communicative, friendly, and hardworking. They did a beautiful job on my solar panels. I wish I could pack them up and take them and my solar panels with me when I have to move in a few years."

Solar Panels FAQs, answered by experts

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.

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional—especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn’t require utility services.

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.

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.
