Utility rules and programs for Plainfield
Public Service Elec & Gas serves homes in Plainfield.
| Utility | Type | Solar export rule |
|---|---|---|
| Public Service Elec & Gas Co | investor-owned | PSE&G follows the state net metering rule: monthly extra kWh are credited to your next bill and carried to the end of your 12-month period, when leftover kWh are paid at the wholesale avoided-cost price. Your installer applies through PSE&G’s interconnection process, and you cannot switch on until PSE&G gives permission to operate (we could not open PSE&G’s page from our server, so fees and timing are not confirmed). |
Program details are from each utility’s own pages (read October 2026). See the New Jersey incentives table for statewide credits and a status for every program.

Solar Panel Installation in Plainfield FAQs
Is solar worth it in Plainfield?
The sun is strong (about 1,140 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the New Jersey incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. New Jersey has no state solar income tax credit that we found; the state’s help is the sales tax exemption, the property tax rule and the SuSI production incentive ($77 per MWh for 15 years on new residential registrations).
Do I need a permit for solar panels in Plainfield?
Usually yes, and the utility may need to approve solar and batteries. Building & Construction Division handles permits in Plainfield; see the permit information above.
