At SUNation, you’re our neighbor.

To Big Solar companies, you’re just a number. Coordinates on a map. Kilowatts on a meter.  SUNation is a locally-owned Long Island solar installation company. Our kids go to the same schools yours do. Our sales people, engineers, and installers all live in your towns. Our only loyalty is to you – and the more than 1,800 Long Islanders who’ve trusted us with their solar installations since 2003.

You know where we live – and we’d love to know where you live, so we can show you how much you can save by running your own SUNation solar power system.

The Bright Side of Solar

There’s a bright side to solar – and it starts in your wallet. We’ll give you four big reasons to install a high-quality solar power system for your residential property.

  1. Immediately start saving money on your electric bill.
  2. Enjoy a low cash investment- about 96 percent of our customers have Zero Out Of Pocket (ZOOP) costs.
  3. “Lock in” your electric rate for the next 30 or 40 years, protecting your family from energy price hikes.
  4. Boost the value of your home (as long as you own – not lease – your solar power system) – by about $3 for each watt of power you install.
The SUNation Difference

SUNation makes it ultra-easy to go solar. From the paperwork to the installation and the certification (needed before you can reap the rewards of tax and energy credits) – we handle it all.

We address all issues with your warrantied installation (unlikely because our solar components are the best in the business), with a qualified crew to arrive on your property pronto and make things right. We believe in a high quality, hassle-free solar installation process – from start to finish.

Long Island’s #1 Solar Installer

We’re local Long Island people, just like you. We treat you as our neighbor, not a number, and that’s why we’re the #1 solar installer on Long Island. It’s the reason our customers give us such rave reviews!
