Commercial Solar Financing Options for NJ Businesses: Capex vs PPA vs Lease vs Direct Pay

For NJ commercial property owners, choosing the right solar financing structure is often as important as choosing the right contractor. Each structure has materially different economics depending on your tax position. Four structures matter in 2026: capex, PPA, operating lease, and IRA Direct Pay.

Capex (Cash or Financed Purchase)

You own the system outright. You capture the federal ITC, MACRS depreciation, bonus depreciation, and NJ SuSI credits directly. Best long-term economics for taxable C-corps with strong tax position.

• Pros: Best total economics, full ownership, simplest accounting
• Cons: Requires upfront capital (or financing), only works for taxable entities that can use federal tax benefits
• Typical payback: 4 to 6 years for NJ commercial

Power Purchase Agreement (PPA)

A third-party developer owns the system and sells you electricity at a fixed rate below your current utility rate, typically with 1.5% to 2.9% annual escalator. The developer keeps the ITC and depreciation. Best for tax-exempt or cash-constrained entities.

• Pros: Zero upfront cost, cash flow positive from day 1, predictable rates
• Cons: You don’t own the asset, PPA developer captures the tax benefits, 15-25 year contracts
• Best for: Tax-exempt entities, credit-constrained owners

Operating Lease

A leasing company owns the system. You pay a fixed monthly lease payment. The lessor keeps the ITC. Middle ground option — predictable accounting without upfront capital.

• Pros: Predictable monthly cost, simple accounting, no upfront cash
• Cons: You don’t own the asset, lessor captures tax benefits, less favorable than capex for taxable entities
• Best for: Owners who want predictable accounting and don’t have strong tax appetite

IRA Direct Pay (Tax-Exempt Entities)

Introduced under the Inflation Reduction Act in 2023, Direct Pay lets eligible tax-exempt entities (501(c)(3) nonprofits, public schools, state/local governments, rural electric cooperatives, tribal entities) elect to receive the 30% federal ITC as a direct cash payment from the IRS — instead of as a tax credit they couldn’t use.

• Pros: Tax-exempt entities can capture federal ITC for the first time, you own the system
• Cons: Requires upfront capital, specific filing requirements, domestic content considerations may adjust credit amount
• Best for: NJ 501(c)(3) nonprofits, public school districts, municipal governments

How to Choose

The right structure depends on three questions:

1. Is your entity taxable, and does it have sufficient tax liability to absorb the federal ITC?
2. Do you have access to upfront capital (or are you willing to finance)?
3. What’s your facility ownership horizon — owned long-term, leased 10+ years, leased short-term?

For most NJ taxable C-corps with 10+ year facility commitments and strong tax position, capex wins. For tax-exempt entities, Direct Pay opens the door to federal ITC capture. For credit-constrained owners with strong cash flow, PPA may be the right fit. We model all relevant structures with your CPA before contracting.
