Jhon Espin has been a Green Sun Energy Services client since October of 2023, when the roof and the solar array were bought on the same day. The roof was finished on 29 December 2023 and the array ten days later.
Two layers off, 3,000 square feet on
This roof had been covered over once before, so two layers of old shingle came off down to the sheathing rather than one — twice the tear-off, twice the disposal, and the only way anyone sees the deck an array is about to be fastened to. Deck protection went over the exposed sheathing, then a GAF Timberline HDZ system in Weathered Wood carrying a 50-year warranty, aluminum drip edge along 355 feet of rakes, eaves and valleys, and a ridge vent along the peak.
22 panels and 8.91 kW
Twenty-two Qcells 405 watt panels came to 8.91 kW on Snap-N-Rack mounting, finished on 8 January 2024, running into a SolarEdge SE7600H Energy Hub inverter with an optimizer on every panel. PSE&G is the utility and the first year was designed for about 11,773 kWh — a little over 1,300 kWh for every kilowatt installed, which is what a well-oriented and largely unshaded roof returns here.
A car charger wired to the inverter, not the panel
An EV charger went in with the array. It is its own unit, but it connects to the inverter rather than to the electrical service panel, which changes what it can do: through the day the car charges directly from what the roof is producing, and after dark it draws from the grid. A charger fed from the service panel has no idea whether the sun is up — it is simply another load on the house. This one sits on the solar side of the system, so the array’s daytime output has somewhere useful to go instead of being exported.
An Energy Hub inverter, and what it leaves open
The inverter is the Energy Hub version rather than the plain one. Nothing about the system today depends on that. What it means is that if this household ever adds a battery, the inverter it already owns is the one that runs it, rather than being the first thing that has to come out. It is a decision made once, at installation, and it cannot be made retrospectively.
Why the roof went first
An array is bolted to a roof for twenty-five years and more, so shingles at the end of their life underneath one are a second job with a date already on them — panels off, roof on, panels back. On a roof already carrying two layers, that job would have arrived sooner rather than later. Ten days of sequencing removed it.
Why Piscataway homeowners choose Green Sun Energy Services

Questions from Piscataway homeowners
RoofingHow important is attic ventilation in Piscataway, NJ?
Very important. Balanced intake and exhaust ventilation can reduce heat buildup in summer, control moisture in winter, and help shingles perform as intended. A roofer should evaluate soffit intake, ridge or other exhaust vents, blocked bays, and the attic's overall air path.
RoofingShould I shovel snow off my roof?
Most homeowners should not climb onto a snowy or icy roof. If exceptional accumulation or ice creates concern, use a qualified professional or a roof rake from the ground when appropriate, and avoid damaging shingles or gutters.
RoofingCan a roof warranty transfer to a new owner?
Certain warranties can, subject to that warranty's own conditions and a required notification procedure with its own time limit. It is worth knowing the process before the house goes on the market rather than during the sale, and a transferable warranty is a genuine selling point.
Solar and RoofingWhat happens when the roof under an existing solar array needs replacing?
The array is professionally removed before the roofing work and reinstalled once the new roof is complete — commonly called a remove and replace. New roof-interface and mounting components are usually advisable rather than reusing ageing penetrations and attachment hardware, though the mounting-system manufacturer's instructions decide what may be reused.
SolarDoes a bigger array always produce more?
Generally yes when everything else is equal, but size alone does not decide annual production. A smaller unshaded south-facing array can outproduce a larger one that is shaded or poorly oriented. Azimuth, tilt, shading, inverter efficiency and module characteristics all bear on it.
