Thomas from Wall, NJ has been a Green Sun Energy Services client since October of 2021. Both jobs were booked on the same day in March of 2021 and finished three days apart that October, which is unusual — most houses take one and come back for the other.
A 14 kW standby generator
The Generac was commissioned on the fifteenth of October and is rated 14 kW on either fuel, so the natural gas it runs on takes nothing off the nameplate. The load survey came to 2,200 square feet and it is switched by a 200-amp automatic transfer switch, so the whole panel is backed.
6.08 kW of solar
Sixteen Hanwha Q.PEAK DUO all-black panels went up three days after the generator, 6.08 kW in total on rail-free mounting, with a first-year production estimate of 7,695 kWh. Sixteen panels is a small array by the standards of this set, and it is the roof that decides that rather than the appetite.
Buying both at once
Doing the two together is the arrangement that makes the most sense and the one fewest people reach on the first visit. The array does nothing in an outage, because a grid-tied system disconnects the moment the utility fails; the generator sits silent on an ordinary day. One crew, one set of permits and one electrical shutdown covered both, and the house came out of a single October with its daytime supply and its outage supply settled at the same time.

Questions from Wall homeowners
SolarWhat is hosting capacity, and can it affect a Wall property?
Hosting capacity is how much distributed generation a part of the grid can take without affecting safety or reliability. A neighborhood with a lot of existing solar can face interconnection limits even where the individual property is ideal for it -- which is why the utility review is not a formality.
Standby generatorCan the generator stay connected during a pressure test?
The machine has to be protected from test pressures beyond what its fuel controls are built to withstand. The fuel-gas code sets out when appliances are disconnected or isolated for testing, and the plumbing contractor follows both that code and the generator's installation instructions.
Standby generatorDoes the residential building code apply to a generator?
It can. For applicable one- and two-family dwellings New Jersey adopts the 2024 International Residential Code, subject to state amendments. Structural and flood-related generator installations may therefore need review under the residential subcode as well as the electrical and fuel requirements.
