"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

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

The morning sun can be better for solar panels because it’s often brighter and clearer than the afternoon sun. The brighter the sun, the more energy solar panels produce. The strongest rays occur during midday, which tends to be prime time for solar energy generation. Most homes get a mix of morning and afternoon sunlight.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

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.
