Solar pricing is one of the most confusing parts of going solar — because companies quote different things in different ways. I’ve been installing in New Jersey for 15 years and I still get homeowners calling me who have no idea if the $38,000 quote they got is a ripoff or a fair deal. So let me break this down properly: what a typical NJ installation actually costs, what’s driving that number, and how to know if the quote in your hand is reasonable.

For New Jersey homeowners: NJ is one of the better states for solar economics right now. Our utility rates are high (PSE&G customers in Central NJ are paying around $0.18–$0.22/kWh in 2026), we have an active SuSI incentive program, and we have full retail net metering. That combination is what makes the math work even after the federal residential tax credit expired December 31, 2025.

What You’re Actually Paying Per Watt

The most honest way to compare solar quotes is price per watt installed — not the total system price. In New Jersey in 2026, I’m installing quality systems at $2.60 to $3.00 per watt for solar-only (no battery). A 10-kilowatt system at $2.80/watt comes out to $28,000 all-in — panels, microinverters, racking, permits, utility interconnection, everything.

If you add a battery — say a Tesla Powerwall 3 or an Enphase IQ Battery 10C — you’re looking at $3.85 to $4.40 per watt total. The battery itself adds roughly $12,500 to $14,000 to the installed cost. Same 10kW system with a battery runs $38,500 to $44,000 depending on battery choice and roof complexity.

If someone is quoting you $4.50/watt or higher for solar-only in NJ, ask them to itemize it. Either they’re using components you don’t need, their overhead is too high, or they’re building in a large sales commission. I see quotes over $40,000 for 10kW systems every week, and I do the same job for significantly less.

What a Typical NJ Home Actually Needs

Most New Jersey homes using 10,000 to 12,000 kilowatt-hours per year need a 7 to 10 kilowatt system. Here’s how to sanity-check that: look at your annual kWh on your PSE&G, JCP&L, or ACE bill. Divide by 1,100 — that’s roughly how many kilowatts of solar you need to offset 100% of your usage in NJ’s climate. A 10kW system producing about 11,000 kWh per year is typical.

The danger zone is installers who undersize the system to win the bid on a lower price. A 6kW system at $16,800 looks cheaper upfront — but if your home needs 10kW to offset your usage, you’re still buying 40% of your power from the utility every month. Over 25 years, that undersized choice costs you far more in electric bills than the upfront savings were worth.

What’s Inside the Price: Component Breakdown

Here’s roughly how a $28,000 10kW install breaks down in NJ:

• Panels (40 × 440W): $7,000–$11,000 depending on brand (budget tier vs. premium like REC or QCell)
• Inverters (40 Enphase IQ8 microinverters): $4,000–$5,000
• Racking and mounting hardware: $1,500–$2,500
• Electrical work (wiring, breaker panel updates if needed): $1,500–$3,000
• Permits and utility interconnection: $500–$1,500
• Labor: $4,000–$6,000
• Overhead, insurance, warranty reserve: remainder

If your electrical panel is older or only 100-amp service, budget for an upgrade — typically $1,500 to $3,000. Jon is also a GAF-certified roofer, so if your roof needs work we can assess and quote it at the same time. Removing and reinstalling solar panels to replace a roof after the fact costs $2,000–$5,000. It’s always better to deal with the roof first.

Panel Brand: Does It Matter?

Yes — but not for the reasons most salespeople tell you. Budget Chinese-brand panels and name-brand panels like REC or QCell both carry 25-year power production warranties. The difference is the labor warranty. Most panels only cover labor for 10 years. After that, if a panel fails, you’re paying $700+ to have it swapped out. REC Alpha panels through the ProTrust installer network carry a 25-year full labor warranty. That’s a meaningful difference over a 25-year product life.

I use REC and QCell on most of my installs. They’re more expensive upfront — maybe $1,500–$2,500 more for a full system — but the performance consistency and warranty coverage make them the right call for a 25-year investment. Budget panels save you money on day one and cost you more in year 12.

NJ Incentives That Reduce Your Real Cost

The 30% federal residential tax credit (Section 25D) expired December 31, 2025. It’s gone for homeowners. What NJ still has — and what makes the economics work:

NJ SuSI Program (Successor Solar Incentive): This is New Jersey’s main solar income program, which replaced the original SREC market. For every megawatt-hour (1,000 kWh) your system produces, you earn one SREC-II certificate. The current ADI (Administratively Determined Incentive) rate for residential net-metered systems is $85 per SREC-II — set by the NJ Board of Public Utilities. A 10kW system producing 12,500 kWh per year earns roughly 12.5 SRECs, about $1,062/year in income for the 15-year life of the program.

Note for commercial property owners and businesses: The 30% federal ITC (Section 48) is still available for commercial solar installations through December 31, 2027. Small commercial rooftop systems in NJ also earn $110/SREC-II (vs. $85 for residential). Non-profits, houses of worship, and tax-exempt organizations can receive an equivalent 30% direct pay grant under the Inflation Reduction Act elective payment provisions through end of 2027.

Full retail net metering: When your panels overproduce, your meter runs backwards. PSE&G, JCP&L, and ACE all offer full retail rate net metering — so every kWh you export earns you the same credit as what you’d pay to buy it. At $0.20/kWh, that’s real money.

NJ property tax exemption: Solar installations are exempt from property tax increases in NJ. A system that adds $20,000–$30,000 in appraised home value doesn’t raise your annual tax bill.

NJ sales tax exemption: Solar equipment is exempt from NJ’s 6.625% sales tax. On a $28,000 system, that’s roughly $1,855 you’re not paying.

A Real NJ Customer Example

I quoted a homeowner in Marlboro last month. PSE&G customer, bill averaging $240 a month — $2,880 a year. She needed a 10kW system. Total installed cost: $26,500. Here’s her math:

• SuSI income year 1: ~$1,062 (12.5 SRECs × $85)
• Electric bill savings year 1: ~$2,600 (covers ~90% of her bill)
• Total year-one financial return: ~$3,662
• Simple payback period: about 7.2 years

After year 7–8, she’s got 17+ years of electricity that costs her almost nothing — maybe a $15/month grid connection fee. Over 25 years, total savings run $80,000 to $90,000 depending on how much PSE&G rates climb. They’ve gone up an average of 4–5% per year over the last decade.

Financing vs. Paying Cash

Paying cash gives you the lowest total cost and the cleanest payback math. But not everyone has $28,000 sitting around, and that’s fine — solar loans are a reasonable choice when the math works.

A solar loan at 4.99% over 20 years on a $26,500 system comes out to about $175/month. If your current electric bill is $240/month, you’re cash-flow positive from month one. You’re paying $175 instead of $240 — even during the loan period. After the loan is paid off, you’ve got essentially free electricity.

The loans to avoid: anything with a dealer fee over 15% baked into the principal, or any loan that promises $0/month payments by hiding the fee in a balloon payment at year 18. Ask for the full loan terms in writing before you sign anything.

Leases and PPAs are different from loans. With a lease, you don’t own the panels. The leasing company keeps the SuSI SREC-II income — at $85/SREC, that’s roughly $956/year you’re handing them for 15 years, or about $14,000 total. Own the system. Cash or loan.

How to Vet Any Quote You Get

1. Ask for price per watt installed. In NJ in 2026, $2.60–$3.20/watt is fair for quality equipment. Above $3.50/watt with no battery, ask why.
2. Confirm system sizing against your actual usage. Get 12 months of kWh from your utility bill. Divide by 1,100. That’s the system size that covers you.
3. Ask who is physically installing your system. Large national companies often subcontract. I do every install myself with my own crew.
4. Get the workmanship warranty in writing. Minimum 10 years on roof penetrations. No verbal promises.
5. Confirm SuSI/SREC-II registration is included. Your installer should register your system in NJ’s GATS system as part of the job.
6. Check their license. NJ requires an EEA (Electrical Contractor) license and a Home Improvement Contractor registration.

Frequently Asked Questions

Is solar still worth it in NJ without the federal tax credit?

Yes — though payback stretched from about 5–6 years to 7–8 years when the residential ITC expired December 31, 2025. NJ’s SuSI program, full retail net metering, and high utility rates still make the math work well. Commercial customers and non-profits still have the 30% federal ITC available through 2027. For residential homeowners, NJ SRECs and net metering carry the financial case.

What is the price per watt for solar in NJ in 2026?

For a quality solar-only system with Enphase microinverters and name-brand panels, $2.60–$3.10/watt installed is the fair range in 2026. Add a battery and you’re at $3.85–$4.40/watt total. Anything above $3.50/watt for solar-only deserves a detailed explanation from the installer.

What is the NJ SuSI program and what does it pay?

SuSI stands for Successor Solar Incentive — NJ’s current solar income program that replaced the original SREC market in 2021. Residential homeowners earn SREC-II certificates at $85/MWh (set by the NJ BPU, reduced from $85 in March 2026). Commercial rooftop systems earn $110/MWh. Certificates are earned for 15 years from installation date and sold through a broker for quarterly income. Small commercial rooftop systems earn $110/MWh.

How does a solar loan compare to just paying cash?

Cash gives you the best total-cost outcome — no interest. A solar loan makes sense when monthly payments are lower than your current electric bill, which is often the case in NJ at today’s rates. The key is to avoid loans with large dealer fees embedded in the principal, which inflate the effective interest rate significantly.

Should I include a battery in my NJ solar install?

With NJ’s full retail net metering still in place, a battery isn’t financially necessary for most NJ homeowners — unlike California where exports earn only 5–8 cents/kWh. A battery makes sense if you have frequent outages, have a medical device that requires continuous power, or want energy independence. For pure financial return in NJ, solar-only still has the faster payback.
