34-panel 10.2 kW solar array in Lacey Township, NJ by Green Sun Energy Services.
Alan Jefferys has been a Green Sun Energy Services client since March of 2017, when the roof and the solar array were bought on the same day. The roof was finished on 6 July 2017 and the array eight days later.
Two layers off, 1,700 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 and twice the disposal on a compact roof. What went back on is GAF Timberline American Harvest rather than the standard line used on most of the roofs described here, carrying the same 50-year warranty, over deck protection on the exposed sheathing, with aluminum drip edge along 142 feet of rakes and eaves.
34 panels and 10.2 kW
Thirty-four Hanwha Q.PEAK panels at 300 watts each came to 10.2 kW on Ecolibrium Solar mounting, finished on 14 July 2017, running into a SolarEdge SE10000A inverter with an optimizer on every panel. JCP&L is the utility and the first year was designed for about 14,317 kWh.
The number worth noticing here
Ten point two kilowatts designed for 14,317 kWh works out at roughly 1,400 kWh for every kilowatt installed, which is at the strong end of anything on this site. Thirty-four panels on 1,700 square feet is also dense coverage — this array uses a great deal of the available roof, and the roof it is using happens to be well placed. Those two things together are why a modest house carries a system this size.
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. With thirty-four panels covering most of a 1,700 square foot roof, that job would effectively be the whole array and the whole roof at once. Eight days of sequencing removed it, and the panels went down onto a deck that had been stripped, seen and covered properly for the first time in two roof generations.

"Glen and his team were great from start to finish. They truly value their costumers and remember who you are long after they've finished installation. He was straight forward and ensured we had a system that met my needs. High quality installation looks great, better than other systems in my neighborhood. It's met and exceeded my expectations." - Robert R: Google
Green Sun Energy Services replied
Thank you. Two layers of shingle off and thirty-four panels on at the same house in Lacey Township is a job with two crews and one deadline, and remembering who you are afterwards is the part that keeps a company honest. Being straightforward about what the system needed to do is how it should start.
Questions from Lacey Township homeowners
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.
RoofingWhat building code applies to residential roofing in Lacey Township, NJ?
New Jersey adopts statewide construction codes through the Uniform Construction Code. Local officials enforce the State-adopted code, so project-specific details should be confirmed with the municipal construction office.
RoofingCan gutters cause roof leaks?
Yes. Clogged, undersized, improperly pitched, or detached gutters can overflow and keep water against fascia and roof edges. Ice buildup in gutters can also worsen winter water problems.
