  • "Sunation is excellent!"

    Reviewed Oct 19, 2021

    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 happy!

    They really promised alot and failed to keep their word and promise in multiple aspects I really dont recommend anyone go solar because it not worth getting in debt and having a system that does not function as promised and have damage done to your roof. The first person I spoke to pauline promised a solar panel instalation with a tesla battery I started the paper work and a few months went by then they changed Pauline as my rep to James he scheduled my instalation and I did not receive a tesla power bank with my instalation he told me that there must have Been a confusion cause they do not normally include them in their installs. I was promised 120 percent of my homes power production but the systems has never produced that much power for me it doing a little more than 70 percent so my 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 instalation I got about 7000 and now have have to pay the difference on top of the 15 year loan. That 5,700 that I have to immediately pay back 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 some one immediately. Today my roof started leaking and they told me the soonest they would have some one out here would be a week. Both of my reps Pauline and James no longer work at sun Nation I have no one to go to for assistance and their service is piss poor I am really not happy with the desicion 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.
