The Direct Answer

A power purchase agreement for solar allows you to use solar energy without upfront costs, but be cautious of the contract terms, including the payment structure, system maintenance, and potential exit fees. For example, a 20-year PPA might have a monthly payment of $150, with an annual escalation of 2.5%.

Before signing a PPA, review the contract carefully, and consider factors like the system's warranty, maintenance responsibilities, and your options for terminating the agreement. It's also important to understand the implications of a PPA on your property value and potential resale.

How Power Purchase Agreements Work

A PPA is a financing option that allows you to use solar energy without upfront costs. The solar company installs and maintains the system, and you pay a fixed monthly fee for the energy generated. The fee is typically lower than your current utility bill, and the agreement can last from 15 to 25 years.

Key Benefits

Costs and Savings
