When Green Team LI began looking for a solar panel company to partner with, we knew we wanted to work with the best. Putting ourselves in our customer’s shoes, we wanted to offer solar power system installation that would deliver the most renewable energy, last the longest, and deliver the most satisfaction to homeowners.

That’s why we’re an authorized dealer for SunPower solar panels.

Solar Panels Head and Shoulders Above the Competition

There’s no question when it comes to overall quality: SunPower produces the most efficient, longest-lasting, and best warrantied solar panels on the market.

With GTLI and SunPower, you get a 25-year warranty on your entire solar system (not just the panels, but the racking system and inverter, too), a 10 year service warranty, and an industry-leading average degradation rate of just 0.25% per year over that 25 years.

Here are some quick facts about what separates SunPower from the rest of the pack:

  • SunPower is the only manufacturer that warranties an entire solar power system
  • SunPower cells produce up to 60% more energy over the first 25 years than conventional solar panel cells
  • SunPower panels have an expected useful lifespan of over 40 years

Just look at how SunPower’s efficiency compares with other solar panels on the market:

A Solar Company That Understands Whole Home Efficiency

Our GTLI team members are not only experts in solar energy but in all aspects of home efficiency. Having the best solar panels on the market is a big advantage for homeowners, but they will only get you so far if their solar production can’t keep up with the energy your home wastes through inefficiencies.

Green Team Long Island is the only major solar installer on Long Island that’s also an approved home performance company. That gives us unique insights as to how your solar panels can best function as a part of your home’s total energy usage.

For example, if your solar panels aren’t producing enough energy to completely power your home with solar, we can help lower your home’s energy usage. Or, if your solar system is producing excess energy, we can help you transition to electric heating, saving you even more in monthly energy bills.

Go SunPower with GTLI and Save for Years to Come on Solar

The benefits of working with a solar installation team who are also expert home efficiency contractors will pay off for decades to come. And, because of the many tax incentives and New York-sponsored low-interest financing, upgrading to SunPower solar is an affordable way for Long Island homeowners to add value to their house and lower their energy costs.
