22 kW Generac standby generator in Lawrenceville, NJ by Green Sun Energy Services.
Lap from Lawrenceville, NJ has been a Green Sun Energy Services client since April of 2024. The load survey came to 2,394 square feet, and the Generac commissioned in July of that year is rated 22 kW on propane and 19.5 kW on the natural gas it runs on here. A 200-amp automatic transfer switch backs the whole panel, so the house never had to be divided into circuits that matter and circuits that do not. Remote monitoring is part of the service cover, and its scheduled maintenance was completed in June of 2025 and April of 2026.
Why Lap chose Green Sun Energy Services
Complete backup power, from sizing and installation to the service that keeps it ready.

Standby generator questions from Lawrenceville homeowners
Can a generator go in the side yard of a Lawrenceville property?
Often yes, provided the side yard satisfies both the manufacturer's clearances and the municipality's zoning requirements. The site review covers the property-line setback, windows and doors, the gas and electric meters, the air conditioner, neighboring structures, flood conditions, service access and any local screening requirement.
What gas pressure does a generator need?
It is model-specific and has to be read off the specification sheet rather than assumed. A current 22 kW model, for instance, specifies a minimum natural-gas pressure of 3.5 inches water column. Different models carry different requirements.
Does a generator need a concrete pad?
Not universally. Approved alternative support systems are permitted for applicable models. Concrete or an engineered platform may still be required because of the site conditions, flood requirements, anchoring, municipal requirements or structural design -- but it is not automatic.
