Michael and Christin from Monroe Township, NJ have been Green Sun Energy Services clients since December of 2017. Two jobs booked together and installed six weeks apart, one to lower what the house draws and one to carry it when the grid stops.
A 16 kW standby generator
Commissioned in February of 2018, on natural gas, behind a 150-amp transfer switch. The load survey recorded 3,300 square feet and a sump pump.
7.25 kW of solar
Twenty-five Jinko JKM290M-60 panels followed in March, on Ecolibrium mounting with a SolarEdge inverter. The design estimate is 9,336 kWh in the first year.
124 feet of critter guard
Mesh was run around the array perimeter at installation rather than added later, which is the only time it can be done without lifting panels that are already producing.
The two systems answer different questions and are often bought together for that reason. The array works every day the sun is up; the generator does nothing at all until the day it is the only thing working.

Questions from Monroe Township homeowners
Standby generatorCan the existing natural-gas service in a Monroe Township home supply a generator?
Often yes, but the gas system has to be evaluated first. The review covers the generator's BTU demand, meter capacity, available pressure, regulator capacity, pipe diameter and length, and every other gas appliance in the house -- furnace, boiler, water heater, range and fireplace among them.
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 generatorHow can a whole house be carried on a smaller electrical service?
Through load management. One or more large loads are controlled so they do not start at the same moment, or shut down briefly if generator demand climbs too high. That is what allows whole-house coverage where the raw sum of every connected load would otherwise exceed the machine.
