“Excellent service, follow-up, and an outstanding experience throughout the entire process! We were extremely happy with Green Sun Energy Services from the first day through the final Township approvals. They even coordinated with the gas company to install a larger gas meter for our new generator. A special thank-you to Jennifer for her…”
Gus · Farmingdale, NJ · 2026
Green Sun Energy Services replied
Gus and Joan, thank you for the kind words and for trusting us with your Generac 22 kW standby generator installation. We're glad the process went smoothly from start to final Township approval, and that Jennifer was able to keep things moving along the way — including getting the gas meter upgrade coordinated. Enjoy the peace of mind that comes with full-house coverage, and don't hesitate to…

“John and Auston were a stellar team, their attention to detail was amazing. Thank you!”
Holmdel, NJ · 2026
Green Sun Energy Services replied
Desiree, thank you for taking the time to leave a review. John and Auston were glad to tackle the full exterior soft wash on your Holmdel home — over 10,000 square feet of stucco, columns, driveway, and pool deck is a serious day's work, and we're pleased the results showed. We look forward to continuing to take care of your property.

“GSES is very professional and the work was exceptional. They did everything they said they would and they were pleasant to work with. No hidden fees, no nonsense, just the great solar system I was looking for. - Ray B. in Howell, NJ | Angie's List”
Raymond and Allison · Howell, NJ · 2026
Green Sun Energy Services replied
Ray, thank you for taking the time to leave this review. It's great to hear that the 21-panel system came together the way you hoped, and we're glad the process was straightforward from start to finish. Enjoy the energy production — it's been a solid array.

“On-time, they did all paperwork with town, the electrical company and oversight agencies. Work was neat, efficient, and timely. The system and warranties explained in detail. Work and system far exceeded our expectations." - Van W. from Hammonton, NJ Angie's List”
Van · Hammonton, NJ · 2026
Green Sun Energy Services replied
Van, thank you for taking the time to leave this review. It was a pleasure getting your 32-panel system up and running back in 2012, and we're glad the installation and everything that came with it — the permitting, the utility coordination, the warranty walk-through — met the mark. We hope the system continues to serve you well.

“Considering solar? Why not have the pros from Green Sun Energy Services provide a free analysis? That's what I did. Made the decision easy for me and my wife and convinced us of the benefits! The whole process from conception through installation went perfectly!”
Gerald · Middletown, NJ · 2026
Green Sun Energy Services replied
Gerald, thank you for sharing this. Thirty-four Jinko panels pulling 14.62 kW is a serious system, and we're glad the process from that first analysis through the November installation on Tanglewood Road went the way it should. Enjoy the production.

“Everything they said was true and accurate. I generated almost a 1000 kWh more than my estimate [in the first year]. The entire year cost me 26 dollars for electric. With the SRECs and the electric savings I should recoup my investment in 4 years.”
Ryan · Tinton Falls, NJ · 2026
Green Sun Energy Services replied
Thank you, Ryan. Production modeling is a promise, and the only honest way to make one is to be conservative about it. The 32 LG panels at your home in Tinton Falls sit across two roof planes, which is a harder array to model than a single slope, so beating the first-year estimate is a good result. Glad the figures have held up.

“We purchased a generator last October and it was installed by Green Sun Energy Services. There were a few delays beyond their control (snow, town permits, technical problem with the actual generator), but I was so pleased with the professionalism of everyone I dealt with Glen, Karen, Jennifer, Chris and all the technicians who worked to…”
Jeannie · Morganville, NJ · 2026
Green Sun Energy Services replied
Thank you, Jeannie. Snow, township permits and a fault in the machine itself is an unlucky run, and none of it is a reason to go quiet. The 17 kW standby at your home in Morganville uses load management to work inside a 100-amp service, which is a neater answer than upgrading the service. Glad the team made the wait bearable.
“Austin visited for the yearly maintenance on our generator. He was courteous, pleasant, and professional. He explained everything he did in detail. I appreciate that Green Sun keeps track of the maintenance schedule so I don't have to. Great service.”
Barry · Lambertville, NJ · 2026
Green Sun Energy Services replied
Barry, thank you for the kind words about Austin — glad to hear the visit went smoothly. You're right that we track the intervals so you don't have to, and we're happy to keep doing that. Your 16 kW unit is in good shape heading into fall, and we'll see you again as scheduled.

“It can be confusing listening to all the companies coming after you to go solar. We chose Green Sun because their installations are the best and because they do not promise anything they cannot deliver. It is easy for people to tell you how much you will save but Green Sun is honest about everything. They have been taking great care of…”
Lon · Farmingdale, NJ · 2026
Green Sun Energy Services replied
Thank you, Lon. Not promising what cannot be delivered is the only sustainable way to sell solar, because the numbers arrive on a bill whether or not anybody was honest about them. Your array has been producing in Farmingdale since 2012, with a generator following in 2013. Two systems and one long relationship.

“You have to go solar and use Green Sun to do it! They were amazing from start to finish. Glen and Chris made sure we understood everything every step of the way. The installers were great as well. They treated our house like it was their own. We are enjoying watching our meter spin backwards!" - Eileen B. from Middletown, NJ. Solar Panel…”
Michael · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Michael. Twenty-four panels have been producing on your roof in Middletown since 2011, which makes yours one of the longest-running arrays we have. Understanding every step is the point of the conversations beforehand, and treating a house like your own is what we ask of every crew that works on one.

“Mike serviced and installed a new battery for my generator.He did a great job and was very helpful with all my questions.Thank You.”
Thomas · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Thomas, and Mike will be pleased. A battery is the single most common reason a standby generator fails to start, so replacing one during a service visit is routine work that heads off a bad surprise later. The 16 kW machine at your home in Middletown is in good order, and questions are always welcome.

“As an engineer, I appreciate and recognize what it takes to plan and execute an excellent job, and thats what Green Sun Energy did for us with the installation, and now ongoing maintenance, of our stand-by generator.”
Ronald and Robin · Fair Haven, NJ · 2026
Green Sun Energy Services replied
Thank you, Ronald. Coming from an engineer that means a good deal. Essential-circuits backup at your home in Fair Haven is a design decision rather than a compromise: the transfer switch carries the circuits that actually matter, which keeps the machine right-sized and the install clean. Planning it properly is where most of the work sits.

“Everything went as planned - we are extremely happy with the process from start to finish. Every step was scheduled and on time. We were kept informed throughout the entire process which made everything go so smooth from the permits, installation and final testing with Glen. We would highly recommend Green Sun Energy Services.”
Mary · Cranford, NJ · 2026
Green Sun Energy Services replied
Thank you, Mary. Permits, installation and final inspection each run on their own clock, and the only way a project feels smooth is if somebody is watching all three. The 20 kW whole-house backup at your home in Cranford went in on that basis. Glad it came together as planned.

“Deciding to install solar electric to our home was an important decision. However, using Green Sun Energy Services was definitely the right decision. The team of installers were superior workers as well as courteous, professional and efficient. The job was completed in 1 1/2 days, and our electric meter immediately started spinning…”
Linda · Farmingdale, NJ · 2026
Green Sun Energy Services replied
Thank you, Linda. Solar is a decision people take seriously and should, which is why the installers matter as much as the equipment: they are on your roof and in your yard for days. A 6.58 kW array and a 17 kW standby generator at the same house in Farmingdale is two crews held to one standard.

“Amazing work - John and his team were excellent and our backyard looks new again. Highly recommend!”
Jessica · Marlboro, NJ · 2026
Green Sun Energy Services replied
Jason, thanks for the kind words about John and the team. Glad the softwash made such a visible difference in your backyard. We appreciate you taking the time to share your experience.

“Our annual service was done yesterday by John he was amazing and has been serving our generator for a few years now, the whole team is amazing!”
Annamaria · Red Bank, NJ · 2026
Green Sun Energy Services replied
Thank you, Annamaria, and John will be glad to hear it. Sending the same technician back year after year is deliberate: the generator at your home in Red Bank has a history, and the person who knows it spots a change faster than a stranger would. Good to hear the whole team came through as well.

“Mike was great! Thorough and professional!! Took the time to explain what he did/replaced.”
Steve and Lisa · Scotch Plains, NJ · 2026
Green Sun Energy Services replied
Thank you, Steve, and Mike will be pleased. The 16 kW Generac at your home in Scotch Plains was sized with two sump pumps in the picture, which is exactly the kind of load that decides a number: a sump that stops during a storm is how a basement floods. Explaining what was replaced and why is part of the visit.
“Great generator service and troubleshooting by Auston. Highly recommend the company.”
Marcin · Parlin, NJ · 2026
Green Sun Energy Services replied
Marcin, thank you for the kind words about Auston — we're glad he was able to take good care of the generator service and troubleshooting for you. It's great to hear from a client who's been with us as long as you have, and we appreciate you taking the time to leave a review.

“Auston Davis Did a great job servicing our generator.”
Middletown, NJ · 2026
Green Sun Energy Services replied
We’re glad to hear Auston Davis did a great job servicing your generator. Since becoming Green Sun Energy Services clients back in January 2013, we truly appreciate the trust you’ve placed in our team over the years. Your service plan, including the Generac extended warranty and scheduled maintenance, is designed to help keep your backup power system reliable and ready whenever you need it most…

“5 stars”
Marilyn · Holmdel, NJ · 2026
Green Sun Energy Services replied
Thank you so much for the 5-star review! ⭐⭐⭐⭐⭐ We’re glad to hear you had a great experience with both your installation and ongoing service. Our team takes pride in delivering a smooth install and dependable support afterward, so it’s great to know that came through. We truly appreciate your trust in Green Sun Energy Services and look forward to being here for you whenever you need us!

“Our house, patio, walkways and driveway was recently soft washed. Very pleased with the result.”
Farmingdale, NJ · 2026
Green Sun Energy Services replied
Thank you, Richard. Soft washing a house, patio, walkways and driveway in Farmingdale is low-pressure work by design: the cleaning is done by the solution rather than by force, which is what keeps siding, mortar and plantings intact. Glad the result was worth waiting for a dry week.

“Mike was very efficient and the service went smoothly.”
Chris · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Chris, and Mike will be pleased. Your Generac standby generator in Middletown was installed by our own crews and is serviced by them too, which is why a visit tends to be efficient: nobody has to work out how the system was put together first. Thank you for the review.

“Mike was awesome and serviced our generator in frigid temperatures!”
Greg · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Greg, and Mike deserves that one. Generators get serviced in whatever weather the calendar hands us, and a cold morning in Middletown is when the machine is most worth proving. Better a hard test in February than an easy one in June and a surprise later.

“A pleasure!!”
Benjamin and Celeste · Holmdel, NJ · 2026
Green Sun Energy Services replied
Thank you so much, Celeste, for your 5-star review! We truly appreciate your trust in us since April 2020. It’s been our pleasure to provide your Generac Service Contract, including scheduled maintenance and your warranty coverage. Knowing that you feel confident and protected with your generator system means everything to our team. Thank you for being valued clients and part of the Green Sun…

“Mike was very polite, quick and efficient. He explained exactly what he would be doing.”
Dave · Highlands, NJ · 2026
Green Sun Energy Services replied
Thank you, Dave, and Mike will appreciate that. Saying what is about to happen before it happens is a small thing that makes a service visit much easier to sit through. The generator at your home in Highlands is on an annual plan, so the same checks happen every year and nothing is skipped for time.

“Michael”
Suzanne · Long Branch, NJ · 2026
Green Sun Energy Services replied
Thank you so much for the 5-star review! We truly appreciate your support and are grateful you chose us for your generator service needs. Our team works hard to provide reliable service, clear communication, and peace of mind with every visit. If you ever need anything in the future, we’re always here to help. Thanks again for your trust in us!

“The young man (Mike) was very competent and nice. He informed me of everything he did during the service call. He spent quite a lot of time and I am very satisfied.”
Carolanne · Bridgewater, NJ · 2026
Green Sun Energy Services replied
Thank you, Carolanne, and Mike will be pleased. Taking the time is the point: the generator at your home in Bridgewater has been serviced by us since 2019, and a visit that is rushed is a visit that finds nothing. Saying what was done as it was done is how the record stays useful to both of us.

“Mike came for a routine maintenance service and did an excellent job. He was very courteous and polite.”
Dominic · Farmingdale, NJ · 2026
Green Sun Energy Services replied
Thank you, Dominic, and Mike will be glad to hear it. Routine is the right word for what an annual generator service should feel like from the homeowner's side: the 22 kW machine in Farmingdale gets the same checks every year, and courtesy on the doorstep is in the job description rather than a bonus.

“Generator service handled by Mike. Courteous.”
Sandra · Red Bank, NJ · 2026
Green Sun Energy Services replied
Thank you, Sandra, and Mike will be glad to hear it. Annual generator service in Red Bank covers the plugs, filters, oil and battery, a full load test and a diagnostics check, and the part that is not on the list is explaining what was found. Courteous and thorough is exactly the pairing we ask for.

“My generator was tuned up by Mike today. Quick and easy. Thanks!”
Tim · Belford, NJ · 2026
Green Sun Energy Services replied
Thank you, Tim, and Mike will be glad it was painless. An annual tune-up on the generator in Belford is plugs, filters, oil, battery and a full load test, done in a morning and logged so that next year starts from a known position. Quick and easy is the intended experience.

“Green Sun Energy installed our Generac generator. It was a flawless project and we were made aware of exactly how it worked. We highly recommend Green Sun Energy”
Tim · Hazlet, NJ · 2026
Green Sun Energy Services replied
Thank you, Tim. Being told exactly how it works is deliberate: a standby generator in Hazlet only earns its keep if the household knows what it will and will not do. Yours went in and has been serviced by us since 2017. Flawless is a generous word and we will try to keep deserving it.

“Mike did a great job servicing our generator.”
David · Belford, NJ · 2026
Green Sun Energy Services replied
Thank you, David, and Mike will appreciate that. The standby generator at your home in Belford is serviced annually, which is less about fixing anything and more about proving the machine will run on the day the grid stops. Quick, thorough and no surprises is what a good service visit looks like.

“I contacted Green Sun after receiving several error messages and interruptions of service of my Generac generator, which Green Sun installed several years ago. As usual, they responded immediately, and service technician John was here exactly when scheduled. He explained what the possible problem might be and proceeded to fix the issue…”
Nadine · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Nadine, and John will be glad to hear it. Error messages are the machine doing its job: a generator that reports a fault is one you can put right before you need it. The Generac at your home in Middletown was ours from the start, which is why a call about it gets an immediate answer rather than a diagnosis from scratch.

“Good company. Great Tech.”
Michael · Belford, NJ · 2026
Green Sun Energy Services replied
Thank you for the positive feedback, Michael! We're glad to hear that you had a great experience with our team and technology. We appreciate your support!

“Very nice, efficient”
Chris · Freehold, NJ · 2026
Green Sun Energy Services replied
We truly appreciate your support and are glad to hear you had a great experience with our team. Providing reliable service and making sure your generator is always ready when you need it is our top priority. Thanks again for choosing Green Sun Energy Services—we’re always here if you need us!

“Mike at Green Sun did a fantastic job with my generator. We’ve trusted them for year to do maintenance on it and haven’t had a single issue. It starts right up whenever is needed. When Mike came this year to service it, he had great attention to detail, replacing/refreshing all necessary components. I hardly even noticed he was there…”
Alexander · Atlantic Highlands, NJ · 2026
Green Sun Energy Services replied
Thank you, Alexander, and Mike will be glad to hear it. Starting right up whenever it is needed is the only thing a standby generator has to do, and it does that because somebody looks at it every year. The machine at your home in Atlantic Highlands is also monitored remotely, so a fault between visits reaches us rather than waiting for the next one.

“Explained everything clearly, good value, and great product.”
Doug · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Doug. Explaining it clearly is the part we care most about. The 22 kW Generac at your home in Middletown was sized from a survey of what the house actually runs rather than from a rule of thumb, and knowing why the number is what it is makes the whole thing easier to live with. Glad the machine has earned its place.

“I have been using this company for years. They always do a great job. The technician Michael made everything super easy. I highly recommend using them for all your generator needs.”
Bryan · Holmdel, NJ · 2026
Green Sun Energy Services replied
Thank you, Bryan, and Michael will be glad to hear it. The generator at your home in Holmdel is on an annual service plan, and the reason a visit feels easy is that nothing has been allowed to drift since the last one. Thank you for the recommendation.

“We had the soft power washing done. The guys were great and did an amazing job. I will definitely use this service again and recommend.”
Anne · Ship Bottom, NJ · 2026
Green Sun Energy Services replied
Thank you, Anne. Soft washing a house on the island means salt air as well as the usual growth, and Ship Bottom exteriors take more of a beating than most. Low pressure and the right solution do the work, which is why the finish lasts rather than simply looking clean for a fortnight. Glad the crew did you proud.

“Mike did a great job. Quick, efficient and friendly. I highly recommend Green Sun”
Ed · Middletown, NJ · 2026
Green Sun Energy Services replied
Thank you, Ed, and Mike will be pleased. Annual generator service in Middletown should be quick, because the machine has been kept in a known condition rather than left to drift between visits. Friendly comes free. Thank you for the recommendation.
