The process was real easy. Matt the sales person was very informative and kept me updated every step of the way. The company was neat, efficient and punctual. I even had my roof replaced with them. The roofing company was 5 stars as well. The best company to do business with. I wish all contractors were like this.

Great experience from start to finish. Carlos provided expert-level guidance and support. He saved me time and money while giving me 25 years of peace of mind in warranty coverage on both labor and materials by choosing the brands. Carlos took my calls while he was on vacation and made sure i was comfortable with ever step of the process. The install was completed in under 4 hours. Clean, neat and professional. Highly recommend!

I had a great experience with Long Island Power Solutions installing solar at my home. From the first consultation through installation, their team was professional, knowledgeable, and very easy to work with. They explained everything clearly, handled all the permits and paperwork, and kept me informed throughout the process. The installation crew was punctual, efficient, and did excellent work — the system looks great and the whole job was completed smoothly. Going solar can feel complicated, but they made the process simple and stress-free. I highly recommend Long Island Power Solutions to anyone on Long Island considering solar. Great company and great service.

We are extremely happy with our 14Kw, 34 panel solar system from New York Power Solutions. The system has been operating for about 3 months and is meeting our high expectations. Our salesman, David Kowalsky, was extremely helpful in analyzing, planning and (very importantly) expediting the installation of our system. David and Power Solutions were very flexible in providing plans, pricing and performance expectations as our system plans evolved as we learned more about residential solar systems in the NYSEG area. We settled on a larger system than initially planned due to anticipated increases in usage for an EV and heat pumps in the future. The installation was very smooth and much faster than I thought it would be. Very professional install team. I really appreciate that the electrician was very open to making changes based on my suggestions about wiring runs based on my knowledge about the attic and chimney chase structures. It made for a much cleaner and better looking installation, with much less exposed conduit. Overall very happy with the installation process and final results. I like the Enphase system and app, very helpful to have both generation and usage tracking. The only negative was that we were unable to get our preferred panels (REC or QTron) due to not being available within our installation timeframe. David was very open and honest about the change and pricing was adjusted without any issues. The supplied panels were similar in terms of specs and performance warranty. I would highly recommend New York Power Solutions and David Kowalsky. They worked very hard to make sure our system was planned, permitted and installed before the federal credits expired.

A+ service! David Kowalsky and his team at LI Power Solutions were amazing. David kept in communication with me throughout the whole process from design to getting permits and final installation. 32 solar panels installed in total. All my questions and concerns were addressed and I can not thank them enough. 5 Stars - Highly recommend!

We are extremely happy with the service. Joe Strzelecki was very professional and completely transparent. Our electric bill is a fraction of what it was less than 30$ that includes connection cost which we all have to pay.

I had 28 solar panels installed on 4/22- Earth Day by Adam and Team 6 from LI Solar Solutions. The team did an excellent job with the project with attention to detail ensuring that the solar and power panels were aesthetically pleasing, cleaned up afterwards. Thank you Adam!!!

A Great Example of Customer Service

Recently I've had solar panels installed by Power Solutions, and I couldn't be happier with the experience. Matt, the representative who helped me, was fantastic. From the very beginning, Matt and his team were incredibly helpful. They were patient and thorough and answering all my questions, no matter how big or small. Matt was always available to speak with me, even outside of regular business hours. This made a huge difference in my comfort level, as I was completely new to solar power. Matt's of the time to explain the entire process, from the initial consultation to the final installation. He broke down the technical aspects of the system into easy to understand terms, ensuring I fully grasp how the panels and the entire setup would work together. If you're considering solar panels, I highly recommend power solutions. They're commitment to customer service is truly unmatched, and Matt's expertise and patients were invaluable throughout the process.

Headache from the start.

I would not recommend this company. It’s been nothing more than a headache since having the panels installed. From not calculating enough panels and not even breaking even year over year, to leaks and having to threaten to sue for a minor repair. Now it’s 3 years into having their panels and I need my roof replaced and they want to charge to remove and reinstall when they had inspected the roof and said we were good to go for the install. It was nothing more than pushing the sale rather than doing the right thing and making sure we wouldn’t be in this situation only a few years in. Now whether it was the solar that is causing the damage or they assessed it wrong, they did a horrible job in one of those fields.

This company is unbelievable

If you looking to install solar just call Joe Galluzzo @ Power Solutions! I took the time and got estimates from 9 different companies and Power Solutions was FAR had the best prices and warranty. Joe Galluzzo was there for us through out the whole process to answer any questions. The company was incredible from start to finish. My production manager Joanie Okula kept me updated at every phase. The installation was fast and very neat. All wires were installed in the attic not running across the roof like most other houses that I see. Now we are enjoying free power and a $18 PSEG bill. I highly recommend calling Joe Galluzzo before you make a decision. Tim P.

Exceptional Experience!

We recently had solar panels installed on our home. Our salesman, Drew Divittorio, was outstanding every step of the way. He clearly explained all of our options and answered every question clearly and throughly. He was very knowledgeable and patient with our many inquiries.

Don't believe all that you read

We went through the whole process and were not impressed. Perhaps Sun Nation is better. The sales person was great, but it ended there, The installers were the B- team. They let a roll or wire fall on our car's rear window. Then they said Safelite was on the way only to find out that was not true. The manager arrived and said they could not come until Monday or Wednesday (this was Friday). Since I needed my car I said Monday. Then I found out that they could not get my window until Wednesday. I needed my car to get to work! They did clean my car, but there was glass all over my driveway that me and my wife were cleaning for days. The problem was that this was the Friday after Thanksgiving. Don't let them install on a day after a holiday. Even the manger said his team failed solar 101 by not telling us to move our car and they did not offer anything to make us whole. Stage two: we were looking to pay our bill they sent the bill and we gave them all our information but because apparently we needed to alert our bank that the amount would be okay it did not go through. Did they contact us - no! Instead they sent the same bill making us feel that we were at fault. We had to reach out to them and get this corrected. Last we had the final walk through and the young women that came was very nice and assured us that she was part of the service team and things would be different. Yes, two days later I had a problem with connection to the grid. So, I called the service team twice, and they never got back to me! I don't know where to turn. Definitely not LI Power Solutions. Not a good experience!!! Be forewarned, look elsewhere!

Satisfied customer!

Very happy with my solar project with Long Island Power solutions. Joe Galluzzo is a great guy and would absolutely recommend anyone interested in Solar to work with him. The roof itself came out beautifully and the crew did a great job cleaning up afterwards. The solar panels look great and the install team worked quickly and efficiently while making sure everything was done well and that it was all properly explained to me. Looking forward to some sunny days and free power.

I had the pleasure of working with Justin Roche through the whole process. He was patient (especially at the beginning when I was comparing several companies) and never felt pushy. They handled all the permitting and once that was done, install was quick and efficient. Panels have been running for just shy of a week and everything seems to be performing as expected. Not that I foresee any problems but everyone at their company has made me feel confident that they would help immediately. Very happy with their company and the whole process

I had very wonderful experience with Li power solutions. They are the best in town. I will mention Steve is so wonderful, he helped me from beginning till system was installed and started on. He was always available with answers whenever i had any issues. He took care of all the application and paperwork which kept me away from all kind of stress. Installation was smooth. I will also say about Brian , he took good amout of time to help me understand about how everything works and answered all my questions patiently. I love the monitoring app that they offer which i can use to keep track of my production. On top of everything going solar took away my electric bill expense which is best for anyone of us. I have alot to write but i would stop and just say they are the BEST solar providers around here. So Go guys !!! Go Solar!!!! .

Gold Standard for solar

I feel compelled to leave this review as I don't normally leave any as I hope my experience will give you cause to at least consider LI Power Solutions for your home or business. I am a financial advisor and always do my due diligence before committing to any significant purchase including my solar system for my home. I compared LI Power with other local solar companies as well as a well known national company for their warranties as well as the quality & performance of the panels being installed. After considering all of these factors I've decided LI Power was the best choice for my home. As for the installation, I had 46 panels installed in a matter of hours! There were (what seemed like) 3 crews dedicated to my installation which came out beautiful! We had one minor issue that was detected several days after the install, and the repair crew came right over and made the necessary adjustment. I am extremely pleased with the value of our purchase and was a pleasure to work with Tom Scala and all the back office support staff. You must meet with them if you are in the market for solar!

Honest and affordable

My reps name is Tom Scala 516-220-6147. This company was the fourth company I interviewed and Tom was spot on. I needed to cut down branches to some very large trees, put on a new roof and every other company told me I couldn’t use my own people to do the work. I also needed an electrical upgrade and had it priced out by other electricians and most of their pricing came in close to $6000 and Power Solutions did it for $3000. I was able to go to 125% in solar panels because I am getting a pool put in and Tom did a Load letter to PSEG to make that happen so we would be able to cover the electric heating of the pool in the summer. Very satisfied and highly recommend and by far the best quote.

My sales agent Justin Roche was wonderful experience made it easy for me to decide what was good for me. No B.S from Justin just the facts.

Our Solar Power Experience

We highly recommend Long Island Power Solution. From beginning to end our experience with everyone involved was pleasant and professional. Our sales person Justin Roche was knowledgeable, friendly, professional and patient. He always answered our calls, answered our questions and put our minds and anxieties at ease. He was with us through every step of the process. He connected us to Atlantic Exteriors for our new roof and gutters. We love our new roof and loved the stress free process as well. The installation team was amazing. They were all polite, respectful, quick, efficient, clean and organized. They left my lawn as if nothing had happened. After the installation we met with our Quality account manager Bill. He patiently showed us how to work the app so that we can be active participants and be able to look at our solar energy panels and energy production. Since then Melinda has answered all our calls and helped us making sure our Envoy is on line. She has been helpful and friendly and professional. Our entire experience with Long Island Power Solutions has been painless and stress free. it has been a pleasure to interact with everyone involved in this process. We would highly recommend Long Island Power Solutions to our friends, family and neighbors.

Don't look anywhere else for you solar needs

Justin Roche was an absolute pleasure to work. I have had more trouble getting cable installed than I did installing solar. He broke down the details step by step and was there to answer the numerous questions I had of the whole process. I thoroughly searched for over 2 years to find the right company and settled on Long Island Power Solutions based on the reviews on this site and my conversations with Justin. He was never pushy and I actually reached out to him a few months after our first conversation to get some more information. I decided on 41 panel system to maximize my solar output it took them less than half a day to complete the job and I could not be happier. I would recommend them to anyone looking to move to clean energy.
