  • "Regret going solar"

    Reviewed Feb 08, 2021

    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.

    I dealt with Scott Simons and the purchase of the solar panels (which are also of the highest quality) could not have been easier. Scott was available and helpful every step of the way answering any and all questions I had throughout the process which was so simple since almost everything can be done online. I would recommend this company highly if you are considering getting solar panels for your home.

    "Extremely Disappointing and dangerous experience"

    Reviewed Jun 22, 2020

    Sunation 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 that this company 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 up sick which prompted me to run to get tested for Covid-19 thus losing more time from work. It was hellish ordeal for me, my family and co-workers. This company does NOT understand we’re living in dangerous times and their install crew needs to receive better training on how to follow proper protocol according to NYS mandated guidelines. Their license should be revoked for putting customers at risk!

    Our staff and teams at SUNation take our actions seriously. The SUNation team has followed and is continuing to follow all NY State guidelines for working during the Coronavirus. Our team members wear masks and our trucks are santized and have sanitizing equipment installed inside. One team member had stomach pains on the jobsite, possibly from bad food. That team member was at work the next day and was not sick nor did any other members of his crew become sick. Our crews have been trained to follow the NY State guidelines and we are continually monitoring them on a daily basis. We are sorry for your illness but we do not believe it is related to SUNation.

    Very happy with the staff and the installation of my solar system. I have had the system a little more than a year and it's performing exactly as they predicted. Very nice people to deal with, I am glad to recommend them to others considering a solar system for their homes.

    Government tax credits, that SunNation explained to me were received, but you still have to consider this an investment for the future due to the remaining cost of the system. I wish the government tax credits were even more generous, It would help people who are on the fence about going solar, make the decision easier.... But I am still happy with my decision to go solar.

  • "Solar panel installation"

    Reviewed Sep 25, 2019

    The process from beginning to end was quite easy and absolutely worth it. I no longer receive an electric bill, except for the $0.40 per day line usage fee. I had the system up since August 8th 2019 and it has produced 2.63 Mwh of electricity, exporting back to the grid 1.09 Mwh as a credit for future use in case of cloudy, snow and shorter sun days in the winter. There was only one day so far that they produced less than I used. It was 85 deg's cloud rainy and very humid.
    I understand each application of the panels will be different for everyone, but not having to pay PSEG $233 per month, which is a lot more than what I am paying for the panels, is great. I really encourage everyone to at least see if this is for you. They do not employ high pressure sales tactics and really do understand the needs of New Yorkers. Also they are a local Long Island business, not some company from out west that has been in business for 6 months.

    I researched multiple Solar companies for nearly a month before settling on SuNation. I chose SuNation because their sales rep, 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 LOVE my new soalr panels and highly recommend SuNation.

    While going through the process of selecting a solar provider I was bouncing around between three companies. It was a very complicated process because it also involved getting my roof done.

    The sales rep from SUNation was simply too aggressive for me. I felt that at every touchpoint he was trying to get me to commit when I was still in the fact-gathering stage. In the end, the products and prices seemed comparable to competitors but I don't feel that I was given the space to seriously consider SUNation.

    We had our solar panels installed in November 2017, and we are so happy we did! We shopped around a bit and had several salespeople come to give their pitch, but none were able to give us the facts and statistics about our needs except for Steve Foley at Sunation. The installation went very smoothly and they were neat and clean. For the past couple of months we have only paid PSEG about $12 for the line into the house. We are currently working on a negative electric usage, which means we are producing more electricity than what we are using. We are so satisfied with the whole process from beginning to end. We are saving money AND we are helping the environment. WIN, WIN !!

The day of installation, the guys worked quickly and cleaned up everything, so that you'd never know they'd been there. The installation looks so good - no pipes are visible and since I have the panels on the front and back, SUNation put nice black ones on the front (no gridlines) so it would look nice on my front roof. I've been very happy with the performance, and also being able to monitor everything on the app. I highly recommend this company. They're knowledgeable and trustworthy.
