"If you need a repair or want to have your panels removed for a roofing project, expect to be calling multiple times a day just to get someone to show up. The lack of communication was matched only by the bad-faith representations. When I needed my solar panels removed for a roofing project, trying to get them to commit to a date for the removal and reinstallation turned a 1 week project into a slog lasting 2 months just because they could not commit to a date without me calling incessantly to ask when they were showing up to finish their work. I was hoping this was was not representative of their company culture and business ethic and gave them another chance when I experienced a failure with my inverter. After reporting a problem with my array I was told repeatedly that they would have someone out there quote, this week, to look at it for weeks. Then they finally told me they already had the replacement part on hand, told me it would be fixed that Thursday and then ghosted me for a few more weeks telling me they needed to RMA the part. When the new part was finally installed, it was not configured to adequately serve my system and my battery backup was suddenly useless. Instead of showing any interest in correcting the issue, they just blamed the batteries, shifted the responsibility for fixing their mistake back to me and disappeared. These folks were pleasant to talk to and laid on the apologies, but the action to make things right did not follow. I cannot recommend them unless you want to waste your time hounding someone just to get a response."

Green Lightning Energy was founded by Jason Plant and Kadin Burns when both of their mothers received excessively expensive estimates from large name-brand solar providers. Our parents wanted the financial advantages and the positive environmental impact that solar energy held, but artificially high prices prevented them from accessing that value. We believed that we could get them a better deal by offering the same high quality solutions, at reasonable prices. We were right, and now, we offer that same value to every homeowner we serve. Some details about our company: - The entire purpose of our company is to make solar affordable for homeowners - We always charge $5,000 to $20,000 (10-40%) less than other installers for identical systems - We offer a 25-year manufacturer warranty on your solar panels and financing through our partner - We give free estimates and speedy responses! - We work with a team of 3-4 licensed electricians who have completed hundreds of installations

"Extremely well. They were able to fit our project in before winter, which we really appreciated. They were also able to do it for thousands of dollars less than other companies using the same exact equipment because of their lower overhead They were wonderful to work with, and it was really great to support people who truly believe in what they’re doing"

Solar Panels questions, answered by experts

Solar panels have a life span between 10 and 40 years, depending on the type of panel. For example, monocrystalline panels can last up to 40 years, while thin-film ones only last between 10 and 20 years. The longevity also comes down to keeping up with solar panel repairs and their related costs .

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.

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

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.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees.
