Latest bad review thumbs down

Christina | Lindenhurst, New York | 03/04/2021

Severe Delay with Minimal Communication

We were told that we would get the system installed by 2020 and receive the 2020 credit. Fast forward to March, still waiting for installation. After we paid the deposit in September, pretty much radio silent through February. We would have gone with a different company who told us they would write off the difference if not installed in time, now we have to eat the cost. Unless you get the promised work/timeline in writing, otherwise do not make any payment.

An Amazing Customer Experience From Start To Finish!

I had my second install with Sunation yesterday at my new house. The team during and before the install were very helpful, professional and courteous. Gina was great! She was always there to answer my questions in detail through out the entire process. Anytime I emailed her I always received a professional and courteous response! During the install Joe did a great job! Joe was also at my first install and I knew I was in good hands when I saw he was part of the crew! Everyone in this company from Rohan my sales representative to Gina to Joe to Tammy truly appreciates their customers! They make the process of going solar as stress free as possible! If you are thinking of going solar go with Sunation! You will defiantly appreciate their quality of work and attention to Customer Service! Thank you Sunation for your attention to quality work and excellent Customer Service!

Rollstone Ave Install

What they promised was delivered. They developed a schedule that they kept to. They explained all of the components and all of the steps to get this project done and how long they will take. The Installers were fast and efficient cleaning up after themselves. The entire install took less that 5 yours. Very happy so far.

Awesome Experience

Very professional - install went very smooth. Install techs walked us through the install process and when finished they gave us a basic run down of how system operates. Highly recommend. Very happy!

SunNation is a superb company! I chose them last year after evaluating multiple bids. They were informed, patient and very professional through the entire process. They dropped the wires into the attic so there is no ugly conduit running over the roof and siding. The installation was done in one day and job site was left spotless. Thank you Marques for all the time you spent with me to design and explaining all my questions!! Fantastic experience with the best company around.

We highly recommend

We recommend using Kevin from Sun nation. Kevin Jaramillo was very knowledgeable and informative. He answered all our questions. It was a quick quiet install that went very smoothly. The installers were very neat ,clean and polite. We highly recommend Kevin and Sun Nation.

Sunation is EXCELLENT! Recommended.

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 happ

Very positive experience working with SUNation. From the sales process to the various logistical efforts (local permissions, array layout, frequent communication, installation), it was really a 1st class effort. Really excited to be joining the 21st century, thanks to SUNation!

Sunation Experience A+

Everyone we had contact with from sales to installation were extremely friendly and helpful. Due to issue with our existing roof we had to postpone the installation 1yr and Sunation honored the original quote, no questions asked. Due to Covid-19 supply shortages they had to substitute panels to a different manufacturer which required additional panels which they provided at no extra charge, increasing my total output an extra 400 watts. Sunation handled all the paperwork and made for a smooth and speedy process from start to finish. 100% satisfied.
