"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."

"I’m really happy I decided to go solar with this company. The team was professional, answered all my questions, and kept me updated throughout the entire process. The best part is that my electric bill is now $0! I honestly didn’t expect to see such a big difference so quickly. I would definitely recommend them to anyone thinking about getting solar panels."

"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 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.

  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don’t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.

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.

Homeowners replace their solar panels after 25 years. That said, you don’t necessarily need to replace them at the 25-year mark. You’ll notice a declining ability to produce electricity over time. Most homeowners spring for a replacement when they notice their energy bills creeping up to regular levels or when solar panel repairs are extensive, frequent, and no longer economical.
