Cash, Loan, Lease, or PPA?

There isn't one financing option that's right for everyone. Understanding how each option works — and the trade-offs involved — can help you make a more confident decision before signing a contract.

There isn't one best financing option

The “best” option depends on your financial goals, how long you plan to stay in your home, and whether ownership matters to you. This guide explains each so you can decide which deserves closer attention.

Paying cash

Potential advantages:

  • Full system ownership
  • No loan payments
  • May maximize long-term financial benefits
  • Simpler ownership experience

Considerations:

  • Higher upfront investment
  • Opportunity cost of using savings
  • Not practical for every homeowner

Solar loans

Potential advantages:

  • Lower upfront cost
  • Ownership of the system
  • Ability to spread payments over time

Considerations:

  • Interest charges
  • Loan terms vary
  • Dealer fees may apply
  • Monthly payments should be understood before signing

Solar leases

Potential advantages:

  • Little or no upfront cost
  • Predictable monthly payments
  • Maintenance responsibilities may differ by agreement

Considerations:

  • Homeowner typically does not own the system
  • Contract terms vary
  • Potential considerations when selling the home

Power Purchase Agreements (PPAs)

A PPA allows homeowners to purchase the electricity produced rather than purchasing the solar equipment itself.

Potential advantages:

  • Minimal upfront investment
  • Electricity costs may be lower than utility rates depending on the agreement

Considerations:

  • Long-term contracts
  • Pricing structure varies
  • Review escalation clauses carefully
  • Ownership remains with the provider

Beware of financing marketing

Common phrases homeowners may hear:

  • “$0 Down”
  • “No Electric Bill”
  • “Free Solar”
  • “Government Program”

Financing offers should always be reviewed carefully before signing. If a phrase sounds too good to be true, ask exactly what it means.
