"He's been the best electrician I've ever dealt with. I was extremely impressed and shocked. not only did he do a phenomenal job, but it's immaculate. There is not a little bit of wire sitting standing anywhere. He cleaned up, he was lovely, he didn't talk much, but you know, he was very busy all day because our entire electrical panel had been blown out from that storm. This is the 1st time since July 4 that we have not been sitting in our house with the lights flashing on and off."

"Excellent experience. We had a connectivity problem with our solar panels. They responded quickly and set up an appointment right away and came when they said they would. The technician very personable. He was able to determine the problem and correct it, updated the software on our system, and explained that maintenance was not necessary. I would highly recommend this company."

"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

A few disadvantages of installing solar panels on your roof include the high up-front costs and the potential for increased property taxes. Installing solar panels can increase the home’s value, which in turn can mean higher taxes. Depending on your area, you should check with your local tax offices for more information. Another potential pitfall is roof leaks from a poor installation, but this shouldn’t be an issue if you hire a reputable company.

The best solar-panel mounting system will depend on your property layout, but you’ll typically want to try for south-facing panels to get the most sun. Roof mounting and wall mounting are both popular, but if your well setup is far away from buildings and other structures you can also set up a freestanding aluminum frame to mount your panels.

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.

Yes, installing solar panels or a solar roof can increase your home's value by approximately 4% to 6%. For a home with a median value of $429,000, this could translate to an increase of around $17,000. A well-maintained solar installation appeals to environmentally-conscious buyers and those looking to lower their utility bills, often helping homes sell faster and at a premium in areas with high electricity rates. However, the exact increase in value depends on factors like the local real estate market, energy costs, and available solar incentives. It's also important that the system is correctly installed and maintained; an older or poorly maintained system may not add significant value, particularly if it's near the end of its lifespan. Other solar features, like panels on a shed, can also boost your home's value.

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.
