Power Purchase Agreements - The Future of Solar?

Affordable Energy Alternatives

There are two PPA's or TPO(third party ownership) options available for new customers in 2026. This blog post is intended to educate the public on the differences between PPA's and PrePaid PPA's so you can make a confident decision in solar energy and battery storage at your home or business.


  • Solar Power Purchase Agreement (PPA): a developer builds, owns, and operates solar on-site; the host buys the electricity at a locked-in rate (no upfront capex). The developer claims tax credits and incentives.
  • Prepaid PPA (prepaid power purchase): the host prepays some or all expected future electricity payments up front in exchange for a deeper discount on the delivered energy. Ownership still typically remains with the developer, who claims the tax benefits unless the contract assigns them.
  • Why this is more feasible in 2026: tax-credit rules changed (direct pay and transferability under the Inflation Reduction Act), lowering need for tax-equity investors and improving project economics. That, plus lower hardware costs, cheaper financing, and additional bonus credits, makes developer-offered power rates more competitive vs. utilities.

How the tax credits work in practice (commercial projects, 2026)

  • Investment Tax Credit (ITC) baseline: the federal commercial solar ITC continues to provide a percentage-of-cost credit (subject to year-specific rules). In addition there are bonus adders (domestic content, energy community, low-income siting, storage pairing) that can increase the effective credit.
  • Transferability: project owners can sell the ITC to unrelated taxpayers for cash rather than use it themselves. That lets an owner monetize credits quickly without finding tax-equity partners.
  • Direct pay (available for certain entities/qualified projects): allows eligible owners to receive the credit as a refundable payment from the IRS rather than as a tax reduction, effectively converting tax credits into cash flow.
  • Result: developers can monetize credits faster, reduce their cost of capital, or pass savings through to hosts via lower PPA rates or larger prepaid discounts.

Who claims the credit in PPA / Prepaid PPA

  • Standard PPA: developer retains ownership and claims ITC/bonuses. Host gets low-cost electricity and no direct tax benefit.
  • Structured sale/transfer: agreements can allocate the right to transfer or receive the credit. Transferability lets a non-taxpayer host sell the credit to a buyer if the host is the owner and the deal supports it, but most hosts prefer a PPA to avoid ownership responsibilities.
  • Prepaid PPA nuance: prepayment changes developer cashflow and can justify a deeper discount, but typically does not transfer the ITC to the host unless explicitly structured.

Why costs are lower vs utilities now

  • Monetized tax credits reduce developer effective installed cost.
  • Transferability/direct pay reduce or eliminate the need for expensive tax-equity partners, lowering financing costs.
  • Large-scale deployment and manufacturing improvements have reduced equipment and BOS costs.
  • Developers offer long-term, inflation-hedged rates and often pass through some of the tax-driven savings, making PPA/prepaid rates below retail utility tariffs.
  • Prepaid structures allow developers to accelerate CAPEX recovery, enabling sharper immediate discounts for hosts.

How to capitalize step-by-step (practical checklist)


Bottom line

PPAs and prepaid PPAs let users access solar energy with no/low CAPEX and receive electricity at rates often below utility retail. Due to transferability and direct-pay options plus lower financing costs, developers can monetize 2026 commercial solar credits more cheaply and pass bigger savings to customers—making these arrangements a financially attractive route to lower-cost renewable energy. If you want, I can run a sample savings estimate for your specific site if you provide roof/land size, average monthly utility bill, and location.
