A Toms River homeowner got a solar proposal in June with the SuSI incentive penciled in at $85 a megawatt-hour. She spent six weeks comparing three installers, waiting on an HOA sign-off, and shopping financing rates. By the time she signed in early August, her installer quietly updated the incentive line to $77/MWh and never explained why. She called us confused, thinking it was a clerical error. It wasn't. The New Jersey Board of Public Utilities cut the residential SuSI rate on July 27, 2026, and every system registering after that date — hers included — locked in the lower number for the next 15 years.
This isn't the general incentive primer we've already published (that one's here if you want the full federal-plus-state stack). This is about one specific thing: what changed on July 27, why it changed, and what it actually costs a homeowner in Monmouth, Ocean, or anywhere else in the state's solar market to register today versus six months ago, or six months from now.
The short version: NJ's residential SuSI/ADI rate dropped $8, from $85 to $77 per MWh, for any system registered on or after July 27, 2026, per a Board of Public Utilities order from its required three-year program review. Whatever rate is in effect when your registration is received locks in for 15 years. Systems that already registered aren't affected. There's no published date for the next adjustment, and the federal tax credit that used to cushion incentive changes like this one is gone entirely for 2026 installs.
What actually happened on July 27
The Successor Solar Incentive program pays New Jersey solar owners a fixed dollar amount per megawatt-hour of energy their system produces, for 15 years from activation. Residential systems participate through the Administratively Determined Incentive sub-program — ADI, the number that shows up on your installer's proposal as the "SuSI rate." On May 21, 2026, the BPU voted on an order tied to the program's mandated three-year review, docketed under QO20020184 and QO26030096. The order directed Board staff to cut the residential ADI rate by $8 per MWh, from $85.00 down to $77.00, effective for any registration received on or after July 27, 2026.
The stated reason wasn't a budget shortfall or a policy retreat on solar — it was the opposite problem. The order cites residential demand "significantly exceeding available program capacity," with homeowners registering new systems at approximately 5.2 megawatts a week during Energy Year 2026. When adoption outpaces the program's capacity targets, the BPU's standard response under the ADI structure is to trim the per-MWh rate rather than cap enrollment outright. It's a demand-based throttle, not a program shutdown.
The full rate history — and why it matters more than one cut
The July adjustment is the third downward step since ADI launched, not the first. Here's the complete residential rate history:
| Period | Residential ADI rate | Change |
|---|---|---|
| Energy Year 2023–24 (program launch) | $100.45/MWh | — |
| Energy Year 2024–25 | $90.91/MWh | −9.5% |
| Through July 26, 2026 | $85.00/MWh | −6.5% |
| July 27, 2026 onward | $77.00/MWh | −9.4% |
That's a 23% decline in the per-MWh rate over roughly three years, entirely driven by NJ's own solar market outperforming the program's capacity assumptions. It's a good problem for the state to have and a real cost for the next homeowner in line. Every one of those step-downs only touched new registrations going forward — a system that registered in Energy Year 2023-24 is still collecting $100.45/MWh today and will keep collecting it through 2038 or 2039, regardless of what the BPU does next.
What $8/MWh actually costs you, in dollars
SuSI math is straightforward once you know your system's expected annual production. A typical New Jersey residential system produces roughly 1.2 MWh per year for every kilowatt of installed DC capacity — so an 8 kW system produces about 9.6 MWh annually. Here's what that means at each rate tier:
| System size | Annual production | Annual SuSI @ $85 | Annual SuSI @ $77 | 15-yr difference |
|---|---|---|---|---|
| 6 kW | 7.2 MWh | $612 | $554 | −$864 |
| 8 kW | 9.6 MWh | $816 | $739 | −$1,152 |
| 10 kW | 12.0 MWh | $1,020 | $924 | −$1,440 |
Those numbers only compare the last two tiers. Stack the full history and the gap gets more dramatic: an 8 kW system registering today at $77/MWh earns $739 a year, or $11,088 over 15 years. The same system registering back in Energy Year 2023-24 at $100.45/MWh would have earned $964 a year, or $14,463 over 15 years — a $3,375 difference on an identically sized system, purely because of when the paperwork went in. None of this is a reason to panic-sign a contract you haven't vetted. It's a reason to know the number before you sign, and to ask your installer to show it to you in writing rather than take a verbal "around $80-ish" estimate at face value.
The registration lock-in mechanic, and why timing is entirely in your installer's hands
Your SuSI/ADI rate is set by the date your system's registration is received by the NJ Clean Energy Program — not the date you sign your contract, not the date panels go on the roof, and not the date your system is activated. In practice, your installer files that registration once your final contract, interconnection application, and permitting are all in order, which typically happens weeks to a couple of months after you sign. That gap is exactly where a homeowner in our opening example got caught: her contract was effectively priced in June, but nothing was actually registered until August, after the rate had already moved.
Two things follow from that. First, an installer quoting you a SuSI number today should be quoting $77/MWh, not $85 or the older $90.91 figure that might still be sitting in last year's marketing PDF. Second, if your own timeline slips — financing approval, HOA review, a permitting backlog at your local building department — that delay can push your actual registration date later without anyone telling you the number changed underneath you. Ask directly: "What rate will actually be on my registration, and when do you expect to file it?" A installer who can't answer that in writing hasn't thought about it either.
What still hasn't changed — and what has, federally
SuSI isn't NJ's only solar incentive, and the ADI rate cut doesn't touch the rest of the stack. Full retail-rate net metering through PSE&G, JCP&L, Atlantic City Electric, and Rockland Electric is untouched. The state sales tax exemption on solar equipment is untouched. The property tax exemption that keeps your assessment from rising because you added panels is untouched. Those three benefits don't have a rate that steps down — they're structural, not administered like ADI.
What has changed, and what makes the July cut sting more than it would have two years ago, is the federal side. The Section 25D residential solar tax credit — the 30% federal credit that used to apply against installed cost — ended for any system placed in service after December 31, 2025, under the One Big Beautiful Bill Act. There's no phase-down, no partial credit, nothing to file on a 2026 return. For the homeowner locking in a lower SuSI rate today, there's no federal credit sitting underneath to absorb part of the difference the way there was in 2023 or 2024. The state incentive is now carrying more of the total-value weight than it used to, which is exactly why the per-MWh number on your proposal deserves more scrutiny than it might have gotten a couple of years ago.
Should you wait for the next cut, or lock in now?
There's no honest way to time this precisely, because the BPU hasn't published a schedule. The July 2026 order came out of a mandated three-year program review, not an annual recurring date — the prior move, from $90.91 to $85, followed a different review cycle. What we do know is that registration pace was still running around 5.2 MW a week heading into the July order, which is the same kind of demand pressure that triggered the last three cuts. If that pace holds, another downward adjustment at some future review point is a reasonable bet, but nobody can tell you if that's six months out or two years out. Waiting on the hope of a rate increase isn't supported by the program's three-year trend; waiting on the hope of exact timing for the next cut isn't supported by anything the BPU has published. The only number you can control is the one attached to your own registration date.

Frequently asked questions
What is New Jersey's current SuSI/ADI rate for residential solar?
$77 per megawatt-hour for any residential system whose registration is received on or after July 27, 2026. Systems registered before that date locked in the prior $85/MWh rate for their full 15-year term.
Why did the NJ Board of Public Utilities cut the rate?
The BPU's May 21, 2026 order (Docket Nos. QO20020184 and QO26030096), part of the program's required three-year review, cited residential demand significantly exceeding available capacity — roughly 5.2 MW a week of new registrations during Energy Year 2026 — and directed an $8/MWh reduction.
Does the rate cut affect systems that already registered?
No. Whatever ADI rate is in effect when your registration is received locks in for the full 15-year SuSI term. Future BPU changes only apply going forward, never retroactively.
How much does the $8/MWh cut actually cost a homeowner?
For a typical 8 kW system producing about 9.6 MWh a year, the difference between $85 and $77/MWh is about $77 a year, or roughly $1,150 over 15 years. A 10 kW system loses closer to $1,440 over the same term.
Is there still a federal tax credit to offset the lower state rate?
No. The federal Section 25D residential solar credit ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act. There's no partial or phased-down version for 2026 installs.
When will the NJ ADI rate change again?
There's no published date. The July 2026 cut came from a scheduled three-year review, not an annual calendar. Given ongoing demand pressure, another adjustment at a future review is plausible, but the BPU hasn't announced when.
How do I make sure my installer registers me at today's rate?
Ask, in writing, what SuSI rate is on your proposal and when they plan to file your registration. Confirm it reflects the current $77/MWh figure, not an older number carried over from stale marketing material, and understand that delays on your end (financing, HOA, permitting) can push your actual registration date later.
