"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

Founded in 2010, Green Sun Energy Services has helped thousands of New Jersey homeowners become more energy independent. We are a leading provider of solar panel installation programs, EV charging stations, GAF Timberline roofing systems, Generac generator installations and maintenance, as well as seasonal services like soft washing and professional Christmas light installation. Headquartered in Middletown, NJ, our local team proudly serves clients throughout Monmouth, Ocean, Middlesex, Somerset, Mercer, and Union counties.
"It’s been just shy of year since we had Green Sun Energy Services design and install a solar array and a standby generator at our home. I’d been thinking about “going solar” for some time. I spoke with one or two other solar-install companies before speaking with Green Sun. Glen, Green Sun head-honcho, came to my home and discussed the technical and economic aspects of the solar array. In addition to being very personable, I found Glen to be professional and exceedingly knowledgeable. I liked that fact that rather speaking with a sales rep, I was speaking with an owner of the company. And I took comfort in the fact that Green Sun is local (at least to me) and has been around for a number of years, has done many solar installs, and has several regular crews of installers. After surveying the attic and taking some measurements of the roof, Glen worked up an estimate for a solar array and standby generator. The estimate detailed what the system would look like, what it could do, and what it would cost. A further and very important consideration for me was what the solar array would look like. Having just completed a significant renovation to the exterior of our home, including a nice new roof, I didn’t want to compromise the look we achieved. In fact, I didn’t want to see the panels at all, at least from the front or sides of my home. Glen assured me that I wouldn’t. In fact, unlike some other solar-install companies, it turns out that Green Sun always sets the panels back at least four feet or so from the side edges of the roof. They “get” it. Since the payout looked good and I was very comfortable with Green Sun and Glen, we decided to proceed. Since part of my project was a standby generator, the electrical work was a bit more involved. Glen’s electrical contractor was amazing. He was easy to work with and really sweated the details. He showed up when we he said he would, and did all the prep work he could in anticipation of the actual solar-panel install and generator delivery. He obviously took great pride in his work, making sure everything was neat and expertly done. No less impressive were the solar-panel installers. Per the layout, they moved a roof vent and took the time necessary to line-up everything in accordance with Greg’s plan. The install proceeded without a hitch and looked great. Inspecting the attic, I couldn’t find a single fastener penetrating the roof deck; every screw/nail was sunk into the rafters. As promised, no part of the array is visible from the front or sides of the house. In fact, in my situation, the solar panels aren’t visible until I stand quite a distance away from the house in the backyard. Glen’s plumbing contractor showed up to plumb the stand-by generator as scheduled. Like the electrical, everything was done professionally and very neatly. In fact, when the inspector came by to perform his inspection, he commented on how neatly the unit was plumbed. As noted at the outset, my system has been operating for about a year. Everything started up without issue. My monthly electric bill is just under $3.00 per month; that’s not for usage –it’s a minimum that must be paid─ I have actually been banking electricity every month, for which I will receive a check/credit from my electric company at some point. I have cashed in the solar credits (SRECs) that I receive every few months. Between the SRECs, my $3-a-month electric bill, and the 30% federal tax credit, I’m on track for a 6-year or so payout. Just a couple of weeks ago, during the April Nor’easters, the power in my neighborhood went out for 4-5 hours. But not at my house; the generator kicked on in a few seconds. My only continuing awareness of the outage was how dark things were outside and the audible, but inoffensive drone of the generator. Bottom line, I couldn’t be more satisfied. The few questions I’ve had have been answered promptly and cheerfully by Glen or his business partner Chris. If you are thinking about “going solar,” or even just getting a standby generator, you really ought to give Glen at Green Sun a call. By the way, I understand that the federal tax credit is being phased out over the next 4-5 years, so if you are interested, you probably should move on it. I realize that this might sound like an “ad,” not a review, but it isn’t. I have no connection with Glen or Green Sun other than being an extremely satisfied customer; this review is simply my way of saying “thank you” to Green Sun."

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
