Susan from Matawan, NJ has been a Green Sun Energy Services client since March of 2022. It began with the generator – installed by another company and commissioned in August of 2021, with the servicing moving to us the following spring, alongside an extended warranty ordered at the same time. Three and a half years later came something much larger: 34 panels making 14.62 kW, each with its own Enphase IQ8 microinverter and a 25-year warranty, completed in November of 2025 and estimated at 18,204 kilowatt hours in the first year. JCP&L interconnected the system in January of 2026. The existing roof was sound enough to build on, so the work stayed with the array, and the generator remains on annual maintenance with monitoring we manage.

Standby generator questions from Matawan homeowners
How far from the property line does a generator need to be in Matawan?
There is no single statewide New Jersey property-line setback for a residential generator. Setbacks are set by the municipality's zoning ordinance, so the requirement is a Matawan question rather than a general one. A generator can meet every manufacturer clearance and still breach a side-yard or rear-yard setback, which is why the zoning review happens before the location is fixed.
Does a standby generator need a permit in Matawan?
A permanently installed generator normally requires New Jersey Uniform Construction Code permits, because it involves permanent electrical and fuel work. Depending on the property and the municipality, building, zoning, floodplain, utility or fire-code review can also apply.
What should a Matawan homeowner look for in a generator installer?
A contractor who can design, permit, install, commission, maintain and repair the whole system rather than one who sells the machine. That means generator sizing and transfer equipment, disconnect and shutdown requirements, grounding and bonding, the manufacturer's own installation requirements, gas or propane capacity and pressure, the model-specific clearances, the municipal zoning setbacks, windows and vents and carbon-monoxide entry points, flood requirements where they apply, permits and inspections, utility coordination, load management, commissioning, warranty registration, monitoring and long-term service. The lowest proposal is not necessarily the lowest cost over the life of the system.
