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

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.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

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.

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.

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.
