New Jersey solar guide
DIY solar in New Jersey: incentives, sizing, and the off-grid angle
New Jersey has one of the most economically attractive solar markets in the country despite middling peak sun hours (4.2/day). The combination of full retail net metering, sales tax exemption on equipment, property tax exemption on PV, and the active SREC market means New Jersey residential solar generates real recurring income beyond just electricity offset.
The SREC market is the differentiator. Every megawatt-hour of solar generation produces one SREC, which you can sell to utilities required to meet NJ's renewable portfolio standard. As of 2026, SRECs trade around $200–$220 each. A typical 7 kW residential system generates ~8 SRECs/year = $1,600–$1,800 in additional annual income.

You can sell Solar Renewable Energy Credits — meaningful additional income.
Used to size your array — more sun hours = fewer panels needed for the same output.
NJ has an active SREC market — even small residential systems can sell solar credits monthly through SREC traders.
DIY install angle in New Jersey
New Jersey allows homeowner electrical permits in most municipalities, but the actual permit process is more involved than in many states. Most townships require stamped electrical drawings for grid-tie systems and a licensed electrician to sign off on the utility interconnection — even if the homeowner did most of the work.
NJ interconnection paperwork: PSE&G, JCP&L, and ACE all require interconnection applications before energizing a grid-tie system. Plan for 30-60 days of paperwork between install completion and actual grid synchronization. Off-grid and behind-the-meter (no export) systems skip this entirely.
SREC registration: after install, register your system with PJM-EIS Generation Attribute Tracking System (GATS) to start receiving SREC credits. Most NJ solar installers help with this; for DIY, the GATS website has a homeowner self-service path that takes about 2 hours to complete.
Sizing for New Jersey sun
New Jersey averages 4.2 peak sun hours/day. Southern NJ (Cape May, Atlantic City) gets slightly more sun than northern NJ (Sussex, Bergen). The variability is small compared to other states.
Sizing strategy in NJ: because of SREC revenue, the optimal residential system size is typically larger than pure electricity offset would suggest. Sizing to slightly over annual home consumption (110-120% offset) maximizes SREC generation without exceeding net metering limits. Some homeowners install up to 150% of consumption when SREC prices are high.
The off-grid question in NJ: off-grid systems don't generate SRECs (SRECs require grid connection and certified metering). For pure off-grid use cases, the NJ math is fine but no different from any other Mid-Atlantic state. The state's solar economics shine brightest for grid-tied homeowners.
