What is a solar PPA
A Solar Power Purchase Agreement (PPA) is a contract where a business uses solar energy without owning the system, and pays only for the electricity generated.
In this model, a solar provider installs, owns, and maintains the system, while the business purchases electricity at a fixed or predictable rate.
This allows companies to switch to solar with no upfront investment.
How solar PPAs work
The structure of a solar PPA is simple:
- A provider installs the solar system on-site
- The provider owns and operates the system
- The business consumes the generated electricity
- The business pays per kWh at an agreed rate
The contract typically runs for 10 to 25 years.
Advantages of solar PPA for businesses
Solar PPAs offer several benefits:
- No upfront capital investment
- Immediate reduction in electricity costs
- Predictable long-term energy pricing
- No maintenance responsibility
- Improved sustainability profile
This makes PPAs one of the most attractive models for commercial solar adoption.
PPA vs buying a solar system
Businesses often compare PPAs with direct ownership.
PPA model:
- No upfront cost
- Lower risk
- Slightly lower long-term savings
Ownership model:
- Higher upfront investment
- Maximum long-term savings
- Full control over the system
The right choice depends on financial strategy and risk tolerance.
Typical PPA contract terms
Key terms in a solar PPA include:
- Contract duration (usually 10–25 years)
- Electricity tariff structure
- Performance guarantees
- Maintenance responsibilities
- Exit or buyout options
Understanding these terms is critical before signing a PPA.
For many businesses, the biggest barrier to solar is capital investment.
PPA removes that barrier completely and turns solar into an operational expense instead of a capital expense.
