Generator failed to start. Karen was able to set up a service appointment the next day. Michael arrived and knew what the problem was before inspecting the generator. Generator running again 10 minutes later. GreenSun installed our Generator app.11 years ago and has been performing serrvicing yearly. Glen,Karen And the entire staff are the best. They really care.

Green Sun installed an EV charger in my garage and were awesome to work with! Their team walked me through everything and helped me get my rebates and inspections without issue. Everything works great and I can not recommend them enough!

My husband and I were so thankful we used Green Sun for the installation of our new generator that a year later (when we decided to move) we used them again! Every member of the crew from first inquiry to final inspection was exceptional. Everyone was very professional, informative and friendly. The communication was amazing -- every step of the way. And their prices were more than fair. Green Sun made the entire process wonderfully easy for us. Special thanks to Glen, Karen and Jennifer who became like family.

From start to finish, Green Sun Energy was reliable, professional, and such a pleasure to work with. The thought of purchasing and installing a generator was very overwhelming to us, but the team at Green Sun made the entire process smooth and easy to understand, with very minimal effort on our end (which was a huge plus!). Every single person we worked with was so pleasant from the office staff to the electricians and plumbers - they gave us a lot of confidence that the job would be done correctly. We would 100% percent recommend Green Sun to friends and family. Thank you Glen and the whole Green Sun Team!

A wonderful experience for a complicated project! I would use Green Sun Energy again for any service they provide. They made the generator install as easy and painless as possible. The crew was kind and efficient. Lots to do for an install such as this but they did it quickly, efficiently and were extremely organized. Just how I like it! Thank you so much!! We feel protected for whatever comes our way.

Since I am working at home it was needed. Glen and Chris were awesome to deal with as they walked us through the process step by step and every time they said someone would be here that person was. It was seamless and very easy to work with them and I would Highly recommend them if you are looking for a generator install.

I was very happy with the job Green Sun has done and the communication they consistently provided. I met someone yesterday who was looking install Solar Panels and they mentioned how painful the sales presentation was (with a very high pressure approach). I told them I have had no issues with Green Sun and I have been very happy. Glen was very professional and informative in the presentation he gave. I also had a neighbor looking for Solar last year and tried to go with a competitor, but they kept delaying things with very inconsistent communication. The communication from both Glen and Chris was always consistent, keeping me in the loop all along the process as they pushed to finish my job before the end of 2020.

Glen and Chris were amazing from start to finish! They always made themselves available to answer any questions and concerns that I had. They are a no BS company, very straightforward and honest, never tried to upsale me on equipment I didn't need. The installers did a great job and made sure the install site was clean of any debris when they finished. We couldn't be happier.

Glen was very professional and answered all my questions and I had many. The installation was on time and professionally done. I signed up for yearly maintenance. The generator kicks in automatically when we lose power. After enduring 11 days without power during Sandy it’s definitely peace of mind! I can recommend Green Sun enthusiastically.

Glen and his team were prompt and professional during both installation and annual maintenance. We lost power during the last hurricane and the generator worked perfectly. Pricing was very good and Glen was even able to get me an extended warranty (promo from Generac). I would recommend Green Sun.

The services that Green Sun Energy have always provided for us have always been top-notch. I would highly recommend them to my family and friends. The power on our street was out during the past storm for about 24 hours. Our generator came on in less than a minute and didn't miss a beat.

Very professional. I installed a new roof and a new 20kw generator and everything went as planned. I am extremely happy with the process from start to finish. Every step was scheduled, and on time. I was kept informed throughout the entire process. Everything went so smooth from permits to installation and final testing. Glen explained each step and setup my expectations honestly and correctly. Glen guided me through the contract and was accommodating to my requests. The installers were excellent and kept a clean area. Karen guided me through appointments and inspections at each and every step. Always returned calls and spent as much time as needed to answer questions. I would highly recommend Green Sun Energy.

Glenn and his team were awesome. From start to finish they were very responsive and didn't treat you like you were just another customer in line. We went back and forth a few times on various options before settling on a final design. Then the township delays began, but they helped us navigate those problems before and after installation! They did things in the installation I didn't even think of, such as ensuring all of the wiring was as hidden as possible. Now we look at other installations and notice those things that we wouldn't have liked to see on our house! After all the township delays it was finally time to turn it on. As with just about any technology it didn't work at first. But that same night I received an email with photo instructions on how to troubleshoot. Unfortunately that didn't work either, but they had someone out the very next day. Anybody can do your install, but how you are treated after they have your money leaves a lasting impression. They don't ignore my emails and are very responsive. If someone is looking for Solar this is the company you want to hire!

Excellent company, excellent service! We've done a ton of research on solar, so we had lots of questions for every sales rep that stopped by our home. Unfortunately, many sales reps just followed a script and often did not know about the specifics of their equipment. We were willing to spend a little more money if we felt comfortable with the company or the sales rep, but none of the reps impressed us. Until we met Glen. He is one of the owners of the company--friendly and informative and knew all of the technical details that we wanted to know. Green Sun actually offered the best price, so it was a double win for us! Glen spent a lot of time going over things and tweaking our system until we were happy--we had researched many different panels used by different companies, so there were alot of questions on our side. He was very patient with us. After we signed the contract, things moved along quickly. Everything was very upfront and communicated well. Glen kept us constantly updated on when the panels would arrive, the workers, everything. Every contractor that showed up was very professional and neat. We paid after each portion was finished, as they had outlined in the beginning, so there was never any anxiety. The design of their system is very sleek--they move exhaust pipes so the panels line up nicely and the wires are hidden in our attic. It shows thoughtfulness and is extra work on their part to not have unsightly wires exposed to weather. We passed our inspection with flying colors and are very happy. It's been 6 months so far and we are still very happy with our system and with Green Sun's level of service to this day. Highly recommend!

The whole project could not have gone any smoother. The sales presentation was concise and informative. Very professional installation process, Green Sun took care of all aspects from municipal approvals to contractor scheduling, Along the way they kept us informed on every single step of the process via email and phone. They gave us the electrical and plumbing installation dates about three weeks in advance and everything came off just as they said it would. The contractors were courteous, friendly and very professional. All we had to do was sign the contract and they made everything happen. Couldn't be more pleased. Best of all, after installation about a month ago we've had the power go out twice in the last week and the Generac performed as advertised.

Sun Green did fantastic job on our new generator! They gave us details about each step and everything went as planned. Glen showed me how to use the system and everybody was super responsive. I’m so glad I went with them and now considering Solar panels for next project.

Great experience. Green Sun completed installation on schedule and had excellent communication throughout the entire process. An equipment issue did arise about a month after installation and they resolved it very quickly and had the system back up and running in no time. I highly recommend them.

Green Sun designed and installed my system 5 years ago. They were meticulous, professional, and did every last thing they said they would. My system is running in top shape because they monitor and maintain it - and they automatically send me checks when I get SRECs. I’m glad I chose Green Sun and I would not hesitate to use them again.

I was very pleased with the whole purchase and installation process. A generator installation requires both natural gas plumbing and electrical work and multiple Township inspections and approvals. Glenn Koedding is an excellent project manager. He kept the project on-track and kept me informed about the status of the installation. The gas and electric installers were very professional and completed their work on schedule. The Township electrical inspector remarked that the electrical work was well done. The price for the generator and installation was very competitive and the progress payments were documented and explained in advance. In short, I was very pleased with the whole purchase and installation process and would recommend Green Sun Energy.
