New Jersey Solar Guide 2026
Everything New Jersey homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.

Quick answer
New Jersey solar economics depend on your roof, utility and quote. This page uses illustrative assumptions of 4.2 peak sun hours, $3/W and 17.0 cents/kWh; these are not verified current market averages or account rates.

- Best for
- New Jersey homeowners comparing solar costs, incentives, and payback assumptions.
- Inputs needed
- annual kWh usage, utility rate, installed $/W, net-metering policy
- Formula used
- Planning production = system kW x peak sun hours x 365 x (1 - 14.08% losses). Retail-value ceiling = production x assumed retail price; actual export value can be lower.
- Method references
- state incentive data, utility tariff checks, Wattcrunch price benchmarks
NJ SuSI: separate the incentive certificate from your utility bill credit
SuSI is the Successor Solar Incentive program. Its two structures are the Administratively Determined Incentive (ADI) and Competitive Solar Incentive (CSI). Small eligible projects commonly look to ADI; project size and category determine the applicable enrollment route.
Certificate income and net-metering credits are separate revenue streams. Do not apply an advertised incentive to every new system without checking the project category, registration date, capacity allocation and issued approval. Earlier SREC and transition-program registrations are not interchangeable with a new ADI application.
Ask the installer who will own and sell the incentive certificates and whether proceeds go to you, a lessor or another party. A fixed program term does not guarantee that an installer's example payment applies to your registration.
Worked example, not an account quote
Illustrative certificate arithmetic, not an offered ADI rate: if an approved project generates 9,000 eligible kWh, that is 9 MWh. An assumed $75/MWh payment would produce $675 before fees. Replace $75 with the incentive in the project approval; do not substitute a legacy SREC price or assume approval is automatic.
Documents to request before deciding
- Request the exact ADI or CSI category and registration documentation.
- Verify the applicable incentive and term with the administrator before subtracting income from cost.
- Separate certificates, export credits, utility charges and financing payments in the proposal.

SuSI certificate income is separate from utility bill credits. Confirm the ADI or CSI enrollment route, project approval and certificate ownership before counting incentive income.

Illustrative 8 kW system in New Jersey
Annual production
10,537 kWh
Retail-value ceiling, not savings
$1,791
System cost (est.)
$24,000
Includes 14.08% planning losses. Valuing all production at retail is a ceiling, not a net-billing savings estimate; actual self-use, export rates and ownership costs change the result. No new Section 25D homeowner credit in 2026.

New Jersey Net Metering Policy
Full retail net metering
New Jersey offers full retail net metering. The Successor Solar Incentive (SuSI) program provides additional compensation for both residential and community solar.
New Jersey Solar Incentives
Programs require eligibility checks and cannot always be combined. Federal 25D credit is $0 for new homeowner-owned systems in 2026.
- ✓SuSI ADI or CSI incentives: confirm project category, registration and approved rate
- ✓Sales tax exemption: confirm eligible purchases
- ✓Property tax exemption: confirm local application
- ✓Earlier SREC or transition registrations have separate eligibility terms

State-specific decision guide
What to verify before signing a New Jersey solar quote
In New Jersey, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–10 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
