What got put on the roof
| Item | Detail |
|---|---|
| System size | 11.2 kW DC |
| Panel count (est.) | 28 panels — assuming 400 W modules |
| Installed | August 2025 |
| Utility | PSE&G |
| Location | ZIP 088xx (New Jersey) |
Predicted vs actual production
The PVWatts number is what we used pre-install. The observed number is what the meter actually counted.
| Source | Annual production |
|---|---|
| NREL PVWatts prediction | 14,112 kWh |
| Observed (utility data) | 14,567 kWh |
| Delta | +3.2% — over the prediction |
What the SRECs paid out
NJ SREC-II / ADI in PSE&G territory — each MWh produced earns one SREC, sold quarterly into the NJ market.
14.57 MWh
SRECs registered through the homeowner’s NJ GATS account for the trailing 12-month window. One MWh = one SREC.
$1,140
First-year SREC-II payout. NJ’s administratively determined incentive currently sets $76–95/MWh for 15 years — this study’s number reflects what cleared.
Before vs after the install
| Window | Average monthly bill |
|---|---|
| Before solar | $380 |
| After solar (est.) | $50 — baseline service + non-offset usage |
| Monthly savings | $330 — before SREC income |
Post-solar bill is a conservative $50/month estimate covering the utility delivery charge and seasonal non-offset usage. Real-life results vary month to month with weather and household load.
Homeowner quote
“I went solar because the math worked. Chris's quote came in $4,400 lower than the lead-gen platform's 'partner' that called me 7 times.”
Notes from the project
James came in with three competing quotes — one from a national lead-gen portal and two from local NJ installers. After my walkthrough we re-bid one of the locals on a cleaner spec, took the $4,400 savings, and routed the SREC-II registration through GATS the week of PTO. Edison sits in a circuit that has been heavily quoted lately so I had him confirm interconnection capacity before signing.
How I measure these numbers
- Production: pulled from the homeowner’s utility net-metering portal (export kWh out of the meter back to the grid + self-consumed kWh from a Sense / inverter API where available). Partial-year installs are annualized in 12-month windows starting at permission-to-operate (PTO).
- SREC payout: the homeowner’s NJ GATS account quarterly statement. Reported figure is the first full 12-month window post-registration. NJ SREC-II / ADI in PSE&G territory.
- Predicted production: the NREL PVWatts v8 number we used in the original quote — same azimuth, tilt, and system loss inputs your installer would file with the utility.
- Before-bill: 12-month average from the utility account history pulled at intake. After-bill is an illustrative $50/month estimate covering delivery charges and non-offset usage; actual months vary with weather and household load.
- Privacy: ZIP3 only (never ZIP+4), first name only, photo only with the homeowner’s written permission.
