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 average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

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.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

Yes, a solar panel can power a TV without a battery, but only if the sun is shining and the panel is generating enough energy. Your solar panel and TV must have the same voltage, and you should install a charge controller and inverter between them so power surges don’t destroy your TV. To watch TV at night, in the early morning and late afternoon, and on cloudy days, your home must be tied to the power grid.

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.
