Property Assessed Clean Energy

Last updated: March 11, 2026

Property Assessed Clean Energy (PACE) is a financing mechanism that enables property owners to fund renewable energy and energy efficiency projects through long-term loans repaid via property tax assessments. This approach combines environmental goals with accessible financing for residential and commercial properties.

Program Structure

PACE programs operate at the county or municipal level, with funding provided through municipal bonds or private lenders. Property owners can finance 100% of qualified solar, wind, weatherization, and HVAC improvements. Loan terms typically range from 10 to 30 years with fixed interest rates between 4% and 8%. The assessment obligation runs with the property and transfers to subsequent owners.

Advantages and Limitations

PACE financing eliminates personal credit requirements and enables energy improvements with zero upfront costs. However, the senior lien position can complicate mortgage refinancing and future property sales. Borrowers must verify adequate energy savings to justify annual PACE payments. Due diligence is essential, as some programs charge high fees or aggressive marketing tactics.
