I highly recommend Sunation for your Home Solar needs. Extremely thorough and professional. Everything they said prior to delivery of the system has been spot on. I am happy to say that my Solar system is producing more than we estimated. Go with Sunation, you wont regret.

The team at SUNation helped us through every step of the process. They gave us all the details on the cost and the size of the installation. They helped us through the financing. The install was done promptly and with the least impact on our our house. Even when we had an issue with squirrels two years later, they were very prompt and repaired the damage. The employees were very courteous and meticulous! I highly recommend them!

The team was professional, courteous, knowledgeable and neat. They answered questions all my questions even after the installation. They did a professional installation. They go the extra mile for their customers. They left my yard clean when they were finished.

SUNation made our overall experience painless and simple. They explained every step of the process in a clear and thorough manner. They cross ever t and dot every I, you very rarely see customer service like this anymore. I have referred them to a few of my family and friends and will continue to do so. Thank you SUNation for making us a part of the SUNation family! I urge everyone to contact these guys, especially if you think Solar is out of reach for you like we did. They will prove otherwise!

Sunation made going solar painless. From permits to installation everything went like clockwork. Everyone at Sunation Knows their job, from the office staff and sales department to the installation crews. It is a pleasure to deal with a company that really knows it's business and knows how to treat it's customers.

SUNation back office support is excellent. They kept me updated on every step of the process. On installation day, the mechanics were very professional. Very neat. No unnecessary roof penetrations. The system works flawlessly.

From start to finish the process went smoothly. The system that was sold to me not only met, but exceeded my expectations. My PSEG bill is a thing of the past and the system looks great on my house.

They offer many options for inverters and panels to fit my needs. They kept me included in the design process as well as supporting documents for estimated production. Installation was smooth and took about 6 hours for 17 panels. Very easy to get in touch with the office staff to ask questions and the permit process closed out easily.

I researched multiple Solar companies for nearly a month before settling on SUNation. I chose SUNation because their sales representant, John, went above and beyond to answer all our questions (he came to my house on three separate occasions). Even after contracts were signed John was extremely attentive and continued to answer my questions as we moved throughout the process. In addition to John the guys that came out for the field assessment, the women in the office, and the guys that installed the system were AMAZING. Everyone was so kind, patient, and helpful from start to finish. They communicate with you throughout the whole process. I highly recommend SUNation.

I have been using Sunation since 2009. Our original solar system, which was installed by another company, had design flaws in the battery back up system. Sunation helped us fix those flaws. When we remodeled our home, we needed to remove our existing system. The only company we called was Sunation to remove and then replace our system with an updated system was Sunation. The experience and professionalism of Sunation mechanics are outstanding. I would not use any other Solar Co in the Nassau/Suffolk NY area.

We have met with multiple solar companies and we chose SUNation over them all. The sales consultant, Frederica, was honest and informative. The installation team were just as excellent. Any questions we had were promptly answered; Frederica even followed up after the install to make sure we were happy (and she arrived with homemade cookies!) This team went above and beyond our expectations. Definitely would recommend this company!
