"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."

"Badly. 2 different techs came out. We paid for a Premium service and within hours of that tech coming out, our burner stopped working completely. Mind you there is a snowstorm. They sent out a new technician and he saw nothing wrong with the system at all. He said we had no oil. He said there was no footprints even going to my intake on the side of my house. It had snowed 2 times since oil was delivered, so that makes no sense. The tech was absolutely sure we had no oil. 3 days since the first visit now and we had oil delivered and the tank filled completely. Only 150 gallons went into my 250 gallon tank. So that's wrong. And I look at the front of my furnace and now see a slow drip from the front underneath the box on the front of the furnace. First tech recommended i replace the electrodes but said it didnt need it. Second tech didnt even mention that and said our system was good. Now, I will have to contact Angi for support and my insurance company. TERRIBLE TERRIBLE TERRIBLE"

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

The time it takes to install solar panels depends on the number of panels and the size of your home, but installation takes between two and three days of work. While most contractors can install the panels over the course of a couple of days, switching to solar energy can take two to three months in total. This includes the time it takes to design the system, procure the parts, obtain the permits, install the panels, connect to the main power grid, and get an inspection.

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.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

Removing solar panels can be straightforward, but it’s not necessarily a simple process. Your contractor needs to prevent damage—not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you’ll need to hire a licensed electrician to disconnect it.
