Joe from Chesterfield, NJ has been a Green Sun Energy Services client since July of 2024. Both jobs were signed on the same day in July and both were finished within a week of each other in September.
A 22 kW standby generator
A Generac 7042-2 rated 22 kW on propane and 19.5 kW on natural gas, running on natural gas, on a 200-amp transfer switch, commissioned in September of 2024. The house is about 3,200 square feet and the switch carries the whole panel. The machine reports to remote monitoring between service visits.
15.18 kW of solar
Thirty-three REC 460-watt panels, finished in September of 2024, with first-year production estimated at 17,971 kWh. Four hundred and sixty watts a panel is at the top of what a residential module delivers, which is why fifteen kilowatts fits on thirty-three of them. The array is held by an S-5! clamp system, which grips the roof’s own seams rather than being bolted through them, and the job took in 200 feet of critter guard.
Why both at once
An array and a generator answer two different questions and neither answers the other. A grid-tied array shuts down the moment the grid does, so it contributes nothing during an outage; the generator runs only during one. Bought together they get commissioned knowing about each other, which is the part that is awkward to arrange after the fact.

Can't say enough nice things about Green Sun. They took care of every little detail, answered every silly question and arranged everything. Had a big solar array installed and a Generac. I got multiple quotes and whilst they weren't the lowest price they were very competitive. They offered better warrantees and a better quality product.
Questions from Chesterfield homeowners
Standby generatorDoes a generator keep the well running during an outage in Chesterfield?
Yes, when the well pump is included in the design. A private well pump is electric, so without power there is no running water at all -- a different order of problem from losing the lights. Homes on a well are among the clearest cases for standby power, and the pump belongs on the load list from the start.
SolarHow does an optimizer system differ from microinverters?
An optimizer system puts DC power optimizers at the modules and a single central inverter elsewhere; a microinverter system puts a small inverter at each module. Both can provide module-level monitoring and rapid shutdown when properly designed -- they are different architectures rather than one being the upgrade of the other.
Standby generatorWhat is a sediment trap for?
It helps stop foreign material in the gas line from reaching the generator's fuel controls. Where the fuel-gas code and the system configuration call for one, it is fitted, and the maintenance schedule includes inspecting or cleaning it.
