Generator, Solar and Soft Washing in Piscataway

Piscataway, NJ · Client since August 2025

Francis from Piscataway, NJ has been a Green Sun Energy Services client since August of 2025, and took three trades inside twelve months.

A 14 kW Generac on a 100-amp service

Running by 24 October 2025. The calculation asked for a minimum of 12 kW under NEC Article 220 Part IV and a 14 kW Generac went in on natural gas, on a composite pad, behind a 100-amp service-rated managed whole-house transfer switch with a load-management module and whole-house surge protection. Everything here is scaled to a compact house: 1,548 square feet, a refrigerator, a dishwasher, a washer and a gas dryer, on a 100-amp service. A service-rated switch matched to 100 amps rather than the more common 200 is the right answer rather than a lesser one – the switch is sized to the service the house actually has. The machine is on our Diamond plan: annual maintenance, extended parts-and-labor cover and remote monitoring that Green Sun runs directly.

12 panels and 5.16 kW

A month later, on 21 November: 12 Jinko 430-watt modules with Enphase IQ8PLUS microinverters, rail-mounted, 5.16 kW rated and estimated at 5,345 kilowatt hours in the first year. Seventy-two feet of critter guard runs the full perimeter, which it would whatever the array’s size – a small array leaves exactly the same inviting gap underneath as a large one, and the wiring up there costs the same to repair either way. The roof needed nothing. The monitoring gateway is mounted outdoors, immediately beside the generator’s transfer switch.

5,747 square feet of soft washing

May of 2026. Soft washing is low pressure and a cleaning solution rather than a pressure washer, which lifts algae and mildew off siding without driving water in behind it.

Two systems, a few feet apart, doing opposite jobs

The array and the generator ended up on the same wall, and the pairing is worth more on a service this size than on a large one. On an ordinary day the panels reduce what a 100-amp service has to deliver to the house. During an outage they contribute nothing at all – a grid-tied array shuts down with the grid, so that no house is feeding power into lines somebody may be working on – and the generator supplies the house instead. Neither substitutes for the other. On 100 amps there is simply less headroom to waste, so the thing that lowers demand and the thing that replaces supply are both working against a tighter number, and both were specified by people who knew the other was coming.

Glen and his team did a Generac generator and a Solar System installation for me. The team did an absolutely fantastic job throughout the entire process. They are very reliable, walk you through all the details step by step, communicated clearly, and completed the work on time. They will help you through design, permits, inspections, various registrations. If you need it, they can help with financing and suggest best options. They are in for the long haul and are more interested in maintaining a relationship with their customers. They are easy to work with. I highly recommended that you consider Green Sun Energy for your generator and solar system acquisition, deployment and ongoing support.

Questions from Piscataway homeowners

Standby generatorCan the existing natural-gas service in a Piscataway 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.

Standby generatorWhich fuel-gas code applies?

New Jersey currently adopts the 2024 International Fuel Gas Code as its Fuel Gas Subcode, which is what governs the piping, testing and shutoff arrangements on a natural-gas generator installation.

Standby generatorWhat actually gets done at a service visit?

It depends on the model, the age and the interval, but typically engine oil and filter, air filter, spark plug inspection or replacement, battery inspection, a fuel-system leak check, sediment-trap inspection, valve clearance where applicable, and inspection of the enclosure and intakes.

Soft washingWill the roof look completely clean the same day?

Algae staining can improve rapidly, but moss and lichen may take longer to weather away after treatment. The objective is to clean the roof safely, not to achieve an instant cosmetic result by damaging the shingles.

Soft washingCan composite decking be cleaned?

Yes, but the decking manufacturer's own cleaning instructions govern. Composite products differ considerably in what cleaning products, pressures and nozzles they permit, and in how they should be treated for stains. The instructions for the actual product are the authority, not a general rule about composites.

SolarWhich direction should the panels face?

South-facing roof planes generally give excellent annual production, but east and west can be very productive too. The design should compare the modelled annual production of each available plane rather than rejecting anything that is not due south.

SolarDo unused credits carry from month to month?

Yes. Eligible excess kWh credits generally carry through the customer's annualised net-metering period, which is what allows strong spring and summer production to offset consumption in the darker months.
