Long Island Solar Power Pioneers


GreenLogic was founded in 2005, making us one of the longest standing solar power providers on Long Island. Since then, we’ve helped our customers save millions in energy bills. Our quality, reliability and high level of performance have made us one of the most referred solar panel companies on the Island. The longevity we’ve enjoyed is thanks to our talented team of energy consultants, designers, installers and customer service representatives, all of whom are some of the most educated and experienced solar power professionals in the area.

Here are just a few of the things that make us unique: 
  • GreenLogic approaches each customer as a lifetime engagement, starting with our commitment to system output, reliable performance, and return on investment. Whether your system is 20 days old or 20 years old, we’ll provide the support you need.

  • We developed proprietary tools and methodologies to accurately predict and track system performance. These tools ensure our custom-designed systems produce the most power and savings at the lowest cost.

  • We partner with world leading solar, wind, and geothermal technology providers so that we can offer best-of-breed materials.

  • GreenLogic has won numerous industry awards for leadership, quality, and customer service including several utility Trade Ally Awards and SunPower's Residential Dealer of the Year Award.

  • GreenLogic is an active supporter of the Long Island communities that we live and work in. Each year we donate a solar power system and sponsor fundraisers as a way to give back.

Your Questions, Answered

Get answers to the questions you didn't even know you needed to ask! There's a lot of information out there about basic solar power system questions, but not much about the small details that can really have an impact on the performance of your system. Our Infrequently Asked Questions section (IAQ) will shed some light on the things you need to know when considering going solar. 


Happy Customers


Read what our customers have to say about working with GreenLogic.

"WOW! Got my system 2 months ago and couldn't be happier. The entire experience was so much better than expected. From being educated about solar (not sold) and if I could benefit. Installers were clean, courteous and respectful of property. Only took about 3 days total. Bryan and all of your support staff was top notch. Best part of it all was my $12 electric bill in January. Can't wait to see bills for May, June, July. Thanks again."
