They really promised a lot and failed to keep their word and promise in multiple aspects. I really do not recommend anyone go solar because it is not worth getting in debt and having a system that does not function as promised and has damage done to your roof. The first person I spoke to, Pauline promised a solar panel installation with a tesla battery. I started the paperwork and a few months went by then they changed Pauline as my rep to James, he scheduled my installation, and I did not receive a tesla power bank with my installation he told me that there must have Been confusion cause they do not normally include them in their installs. I was promised 120 percent of my home power production, but the system has never produced that much power for me, it did a little more than 70 percent, so I still pay around 60 dollars of electricity on top of the solar panels. They told me I would get exactly 12700 dollars of tax reimbursement so that I can pay off half of the installation. I got about 7000 and now have had to pay the difference on top of the 15-year loan. That 5,700 that I have to immediately payback, so there really is no saving as expected, and the 0 money out of pocket cost is a lie. They told me that if my ceiling ever had a leak that I would need to call right away and that they would send someone immediately. Today my roof started leaking, and they told me the soonest they would have someone out here would be a week. Both of my reps Pauline and James no longer work at sunNation. I have no one to go to for assistance, and their service is poor. I am really not happy with the decision I made with this company to go solar.

Scott, I would like to say what a fantastic job Greg and the crew did today with my installation. All of them each and every one of them were very kind, curious and enjoyed my olde English bulldogge puppy. He misses them already. Two of my neighbors just came over to see what a great job was done, one of which has solar and is pissed he didn't go with Sunation. Greg knows who I'm talking about lol.

This company came highly recommended to us as one the premier solar panel installers in Long Island so my husband and I put our trust that during these times of the pandemic, Sunation would do the right thing by following all protocols mandated by NYS. Unfortunately, on the day of the install, all but 1 of the 5 installers that showed up at my home ignored the mandate to wear a mask. One of the installers got sick with a stomach virus and instead of being sent home immediately by the supervisor, remained at my home, used my bathroom several times and while going in and out of my home, did NOT wear a mask or gloves. I ended getting sick and running to get tested for Covid-19 which resulted in being quarantined for 2 weeks after having gone back to work! My life was turned upside down because of Sunations inability to properly train its crew during these times....not a good experience at all. Their install crew needs to receive better training so they learn how to follow OSHA and Dept of Health guidelines during these challenging times. I have been reaching out to the company but they do not accept the fact that they did any wrong.

The entire crew was efficient and professional. Customer service is SO EASY to contact! get a live person every time! And they really made me feel like I was their only customer. Other customers have come together to become a huge family with the company! I always recommend SUNation. When I retire, I'm working for them just for fun!

Dealing with Contractors can be a nightmare but this Company does everything they said they would do and more . My solar was installed about 4 years ago and I still brag about Sunation and their employees. They did the work on time showed up everyday until the job was complete. They are a great company to deal with and remain friendly with. Iâ ve called them twice and each time I was treated like a brand new customer .

Fredericka, our saleswoman, was knowledgeable and helpful in configuring the system. She was accessible for any questions we had. Install took 1 day. Had questions about notifications on my solar app at 10pm , and they got back to me immediately. I recommend this company.

Sunation installed solar panels for us 9 years ago which included installation of a lifetime roof. Several years ago squirrels gnawed on some of the wires. They were quick to repair and provided a solution to eliminate the problem. Our electric bills after installation are around $400 a year versus what I estimate with inflation would be $4,000 per year had we not installed the panels. Our 10,000 KWH system still produces about $12,000 KWH per year.

The transition from Level Solar to SUNation Solar Systems was seamless. I was very happy and relieved that such a great company took over where another dissolved. One of the great things is their customer service. They make you feel happy and like you are part of a family no matter what you are calling them about and that is a good feeling to have. Their referral program and other countless ways that they give back to others is a great thing to see. It's a no-brainer why they won 10 years in a row for the best solar business on Long Island!

Kevin Stafford was excellent in describing what the process would be and provided an estimate on the number of panels as well as the location and alignment on my roof. He explained the tax credits very well. His knowledge of the various panel types was helpful. The office support folks were very helpful with scheduling the appointment for the engineer and in filing the permit. The technician who came to measure was professional and very thorough. He asked many good questions and answered all of mine completely. Kevinâ s follow up has been terrific. Iâ m looking forward to continued professionalism as the installation begins. I selected SUNation after getting bids from four other companies.

The solar panel system installed by SUNation was top quality, it has performed as advertised and has significantly reduced my energy bill to almost ZERO. I still have to pay a few dollars a month for connection service but otherwise no bill. From sales to installation it was a smooth process and would recommend them to anyone interested.
