Electric Bills Exploding? Here’s What’s Happening
May 9, 2026Solar Loans — The Pitfalls Nobody Warns You About
May 9, 2026Three ways to finance solar — three very different outcomes. Jon breaks down exactly what each option means for your wallet over 25 years.
Cash Purchase
Best financial outcome. You own the system, you get all the savings, you get the SRECs, and you get the home value increase. Payback typically 7–8 years in NJ, after which electricity is essentially free for 15+ more years. Not everyone has $25,000–$35,000 available.
To understand why cash is the benchmark, run the full 25-year math. A 10 kW NJ system at $2.80/watt costs $28,000. Add SREC income: $85/SREC × 10–11 SRECs/year × 15 years = $12,750–$14,025. Add electricity savings: roughly $2,000/year × 25 years = $50,000. Total 25-year benefit: approximately $62,000–$64,000. Net gain after the $28,000 cost: $34,000–$36,000. Every other financing option gets measured against that number.
Solar Loan
You own the system from day one. You get SRECs, full savings, and home value benefits. Monthly loan payments (typically $120–$200/month for a NJ system) are often lower than the electric bill they replace. Loan paid off in 10–12 years, then free electricity. Best option for most homeowners who don’t pay cash.
The interest cost is real but manageable. On a $28,000 loan at 6.99% over 15 years, total interest is approximately $15,700 — making your effective system cost $43,700. Still a strong return given the $62,000+ in 25-year benefits. The key is keeping the loan term short. A 25-year loan on the same amount at the same rate costs $31,200 in interest — nearly double. Short term wins in the long run.
Solar Lease
The leasing company owns the panels. They collect SRECs. Your payment typically escalates 2–3% per year. No home value increase from owned solar. Home sale complications. You get cheaper electricity, not solar ownership. Rarely the best financial outcome for NJ homeowners.
The hidden cost in NJ is the SREC transfer. A 10 kW system generates 10–11 SRECs per year at $85 each. Over 15 years at the fixed SuSI rate, that’s $12,750–$14,025 in program income that goes to the leasing company, not you. Add the payment escalator and the absence of any home value benefit, and the 25-year cost-benefit of a NJ solar lease typically runs $15,000–$25,000 worse than ownership. That gap is real money that you hand over for the convenience of not having a loan.
Power Purchase Agreement (PPA)
Similar to a lease — you pay per kWh produced rather than a fixed monthly fee. Company owns the system, keeps SRECs. Can make sense if your credit doesn’t qualify for a solar loan, but compare the 25-year cost carefully. PPAs typically start 10–15% below your current retail rate with 2–3% annual escalators. Run the math: by year 15, your PPA rate may have escalated past the grid retail rate — at which point the “savings” disappear entirely.
The NJ SREC Factor — Run the Numbers
NJ SRECs are the single biggest reason ownership beats leasing in this state. Under the SuSI ADI program, residential systems earn $85 per SREC-II for 15 years. One SREC-II is generated for every 1,000 kWh of production. A 10 kW NJ system produces 10,500–11,500 kWh/year, generating 10–11 SRECs worth $850–$935 annually — and this is a fixed, guaranteed rate for the program term, not a market-traded commodity.
When a solar salesperson shows you a lease comparison and says it’s “just as good,” ask them specifically: where is the SREC income in your 25-year model? A legitimate comparison accounts for all revenue streams. If the model they’re showing you doesn’t include SREC income for the ownership scenario, the comparison is incomplete and almost certainly misleading.
What Happens When You Sell Your Home
Owned solar — whether you paid cash or used a loan — adds value to your NJ home. Studies consistently show a $3,000–$5,000 premium per kW of owned solar in home sales. A 10 kW owned system adds $30,000–$50,000 in appraised value.
Leased solar complicates home sales. The buyer must either qualify to assume the lease (their lender’s approval required) or you must buy out the lease — which often costs $8,000–$20,000 at mid-contract. Some NJ buyers walk away from homes with solar leases because of the complexity. Jon has talked to sellers who thought the solar was an asset until they listed the house and found out the lease was a liability.
The Simple Rule
If you can qualify for a solar loan, own the system. The loan is almost always a better financial outcome than a lease or PPA in New Jersey.
The Lease Fine Print That Trips Homeowners Up at Resale
Jon has talked to NJ homeowners who were surprised at closing when their buyer’s attorney flagged the solar lease. Here’s what typically happens. The buyer’s lender requires that the lease either be paid off (bought out by the seller) or assumed by the buyer. Lease buyout at mid-contract usually means paying the net present value of remaining payments — often $8,000–$20,000 at the 5–10 year mark. Lease assumption requires the buyer to qualify separately with the leasing company, which is a separate credit process from the mortgage qualification, and some lenders won’t close with a lease assumption in place.
The practical result: some NJ sellers with solar leases have to reduce their asking price to compensate the buyer for assuming the lease, or pay it off at closing out of their proceeds. In a competitive market, a home with an owned solar system commands a premium. In a soft market, a home with a solar lease can be at a disadvantage. This is a 25-year decision — think about where you’ll be in 10 or 15 years before signing a lease.
Running the Real 25-Year Comparison
The most honest way to compare financing options is a 25-year total cost and benefit analysis. It should show, for each option: total amount paid (cash, loan payments, or lease payments) over 25 years, total electricity savings at current rates with a modest escalator, total SREC income under NJ’s SuSI program for owner-financed options, estimated home value contribution, and net 25-year financial position. This is the calculation Jon runs for every NJ homeowner who asks for it. The lease and PPA look competitive in the first year because of lower upfront cost. The ownership options — cash or loan — usually look substantially better by year 10 and dramatically better by year 25 in NJ, specifically because of SREC income.
What to Do If You Already Have a Lease
Some NJ homeowners who call Jon already have a solar lease on their home — usually one signed 5–8 years ago during the national lease-push that dominated the solar industry in that era. If that’s your situation, a few things to know. First, you can usually request a buyout price from the leasing company — this is the lump sum that would transfer ownership of the system to you. Get that number and compare it to the 25-year remaining value of owning the system (SREC income + electricity savings). Second, if you’re refinancing your mortgage, flag the solar lease to your lender early — some lenders have specific requirements around solar leases that can complicate the refinancing process if not addressed upfront. Third, if your system is more than 10 years old and the lease is near term, evaluate whether the buyout makes sense or whether the system will reach end-of-life before you recover the buyout cost.
NJ SuSI Program: What Ownership Gets You
New Jersey’s SuSI ADI program is one of the strongest solar incentives in the country and it’s available exclusively to system owners — not leaseholders. The Adjustable Block Incentive pays $85 per SREC-II for residential systems, fixed for the full 15-year program term from your interconnection date. The block pricing is set when you apply and lock in — so even if NJ adjusts the program in future years, your rate stays at $85/SREC for your full term. This is income that flows quarterly or annually through your SREC aggregator, deposited to your bank account, with no additional work on your part after registration. It is one of the clearest financial arguments for solar ownership over leasing in any US state.
In New Jersey, the solar ownership economics are strong enough that the right financing question is rarely lease vs. loan — it’s which loan, at what rate, for what term. That’s where the real analysis should happen. The lease comparison is mostly useful for understanding what you’d be giving up.
