Conor Egan has been a Green Sun Energy Services client since August of 2021, when the roof and the solar array were bought on the same day. The roof was finished on 23 April 2022 and the array a month later.
Two layers off, 3,300 square feet on
This roof had been covered over once already, 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 before an array is fastened to it. Deck protection went over the exposed sheathing, then a GAF Timberline HDZ system in Charcoal carrying a 50-year warranty, aluminum drip edge along 198 feet of rakes and eaves, and a ridge vent along the peak.
A simple roof, which is the easy kind to work on
Three thousand three hundred square feet with only 198 feet of edge is a plain roof — long runs, few valleys, not much cut into it. It reads as an unremarkable detail and it is the difference between a straightforward array and an awkward one. Valleys and hips break a roof into small faces, and small faces mean short panel rows, more flashing, more penetrations and more places to get wrong. A roof like this one takes thirty-six panels in clean rows.
36 panels and 12.96 kW
Thirty-six Hanwha Q.PEAK DUO panels at 360 watts each came to 12.96 kW on Snap-N-Rack mounting, finished on 23 May 2022, running into a SolarEdge SE11400H HD Wave inverter with an optimizer on every panel. JCP&L is the utility and the first year was designed for about 15,185 kWh.
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 become a second job with a date already on them — panels off, roof on, panels back. A roof already carrying two layers has less time left than most. Doing it first, a month ahead of the array, put thirty-six panels onto a deck that had been stripped, seen and covered properly, under a 50-year system.

Questions from Brick homeowners
SolarHow is the number of panels for a Brick house decided?
It starts with the home's actual electricity use, then with how much usable roof or ground area there is. A proper design looks at twelve months of consumption, expected future use, roof orientation, shading, roof dimensions, code-required setbacks, module wattage and the limits the utility places on interconnection.
RoofingCan a skylight leak when the shingles are fine?
Yes. The source can be the skylight flashing, a failed seal, an improper earlier installation, condensation, or the transition between roof and skylight. Fogging between the panes is a failed glazing seal rather than a roof leak, and replacing the roofing around it will not restore the glass. If a skylight is near the end of its life, reroofing is the most economical moment to replace it, because the new unit, its flashing and the underlayment can be integrated from the start.
SolarDoes production have to match usage every month?
No. New Jersey net metering works over an annualised period rather than month by month, so credits accumulated in high-production months are available during the low-production ones.
