Sunation is EXCELLENT! Recommended.

Sunation was an absolute pleasure to work with! From our initial consultation with Cameron, to agreeing on the perfect system and layout for our needs, to contract and financing, through install and post-install service, Sunation has delivered on what they promised, and did the work on time. The system was installed neatly (everything is labeled, and actually blends in with the roof and siding) and is leak-free (a few storms this summer helped us confirm this, LOL). Sunation walked us through every step of the process - permitting, PSEG net metering, permits, town electrical and building inspections, and our Certificate of Compliance - and was excellent in communicating the process and next steps. Our system has been in service for several months now, and is performing exactly as expected! Our electric bill has been between $12 - $14 per month (for the backup connection to the grid), and we have already developed a bank of kw credits from our system's production in excess of our use. We recommend Sunation to family and friends!!If you are interested in going solar, check out Sunation! They did right by my family, and we are very happ

Latest bad review thumbs down

Christina | Lindenhurst, New York | 03/04/2021

Severe Delay with Minimal Communication

We were told that we would get the system installed by 2020 and receive the 2020 credit. Fast forward to March, still waiting for installation. After we paid the deposit in September, pretty much radio silent through February. We would have gone with a different company who told us they would write off the difference if not installed in time, now we have to eat the cost. Unless you get the promised work/timeline in writing, otherwise do not make any payment.

Very positive experience working with SUNation. From the sales process to the various logistical efforts (local permissions, array layout, frequent communication, installation), it was really a 1st class effort. Really excited to be joining the 21st century, thanks to SUNation!

Sunation Experience A+

Everyone we had contact with from sales to installation were extremely friendly and helpful. Due to issue with our existing roof we had to postpone the installation 1yr and Sunation honored the original quote, no questions asked. Due to Covid-19 supply shortages they had to substitute panels to a different manufacturer which required additional panels which they provided at no extra charge, increasing my total output an extra 400 watts. Sunation handled all the paperwork and made for a smooth and speedy process from start to finish. 100% satisfied.

Community solar program is great

Sunation's community solar program on Long Island is an excellent program for anyone who wants to do the right thing and/or save money. Large-scale installations are more efficient and easier to maintain. Great program.

SUNation Solar is an AWESOME Company!!! Our salesman Johnny Leach is a gentleman and is very informative on Solar Systems. It was easy to understand what he was saying to my wife and I, which made our decision easy to male and have SUNation install the Solar Panels. The company then made the process easier by doing all the leg work for us contacting PSE&G and Babylon Township for the permits needed to install our Solar System!! The office staff were great, always in contact with us every step of the way throughout the whole process to the end!! Thank you SUNation!!!! You are a well oiled machine!! Never experienced this kind of friendliness with any other company in my entire life!!! You're the BEST!! Stephen Aponte

Great Job!

Chose them as recommended by a co-worker. Detailed analysis conducted for where placement/amount would go back to accommodate usage comparable with to my previous years’ consumption. Works great, bills are pretty much a connection fee.

Best Solar

I chose SUNation because it’s the greatest solar company in the nation. The service was great and I have loved my panels since day 1. I am glad I was convinced to go with them sooner than later. No negative issues, just absorbing energy everyday.
