Buying, a monthly lease or PPA, and a prepaid agreement can each put rooftop solar on a suitable New Jersey home. They differ in when you pay, who owns the equipment, who maintains it and what happens later. Compare actual offers using the same assumptions.
The three common paths
Buy: Pay cash or use financing and own the system from day one. Monthly lease or PPA: A provider owns the system while you make payments under the agreement. Prepaid lease or PPA: Make an upfront payment while the provider initially owns the equipment. A future purchase option may be available.
| Question | Buy | Monthly lease / PPA | Prepaid lease / PPA |
|---|---|---|---|
| When do you pay? | At purchase or through a loan | Regular payments | Agreed upfront amount; check fees |
| Who owns the system first? | Homeowner | Third party | Third party |
| Who maintains it? | Generally homeowner, subject to warranties | As specified in agreement | As specified in agreement |
| Can ownership change later? | Already owned | Depends on agreement | May be an option; terms vary |
Compare total costs, not just a first payment
For a purchase, compare cash price or total loan payments. For a monthly plan, review every scheduled payment or per-kWh rate, annual escalators and end-of-term costs. For a prepaid plan, review the upfront amount plus any service, transfer or other charges. Use conservative production and utility-price assumptions across all three proposals.
Ownership affects control and service
Owners generally control their equipment and handle maintenance, subject to warranties and service plans. In a lease or PPA, the provider initially owns the system; the contract governs monitoring, repairs, roof work, insurance and changes to the equipment. A prepaid amount does not by itself make the homeowner the owner.
Check who receives incentives
New Jersey incentive allocation depends on program rules, system registration and contract terms. The federal Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. A third-party owner may qualify for a business credit only if applicable requirements are met; its value is not automatically passed through to the homeowner.

Plan for a home sale
With a purchased system, a loan may need to be resolved as part of the sale. With a monthly or prepaid agreement, review buyer assumption, transfer requirements, buyout price and timing. Even an agreement with no regular payments may carry transfer conditions. Read the home-sale guide.
A useful side-by-side checklist
- Total payments and expected electricity value over the same period
- Initial and future equipment ownership
- Monitoring, maintenance, warranty and roof-work responsibilities
- Allocation of state incentives and any business tax benefits
- Home-sale, transfer, purchase and end-of-term terms
Pricing, production, eligibility and agreement terms vary by home and provider. Ask for all assumptions and commitments in writing.
