A solar lease generally charges for use of provider-owned solar equipment, while a PPA generally charges for the electricity that provider-owned equipment produces. Both are commonly forms of third-party ownership. The most meaningful differences are how payments are calculated and how the agreement handles production.
Fixed-style payment versus production payment
A lease payment is commonly a recurring amount defined by the lease schedule. A PPA payment is usually calculated from solar production multiplied by a per-kilowatt-hour rate. Read the actual contract because products and terminology can vary by provider and market.
Escalation can appear in either structure
A lease or PPA may include an annual increase. Ask for the complete payment or rate schedule rather than focusing only on year one. Compare that schedule with a realistic view of utility charges and remember that future utility rates cannot be guaranteed.
Shared questions still matter
Ownership, monitoring, maintenance, insurance, roof work, home-sale transfers, purchase timing and end-of-term choices matter under both structures. A payment label does not replace a complete contract review.
What to confirm before you move forward
- ✓Determine whether payment is fixed or production-based
- ✓Request the full payment schedule
- ✓Review any production guarantee
