C-PACE financing lets commercial property owners fund HVAC, solar, and resiliency upgrades with 100% financing repaid through the property tax bill at 5.5%-9.5% fixed rates over 20-30 years, though the senior-lien structure requires existing mortgage lender consent, which is the most common closing bottleneck.

How residential and commercial solar EPCs should structure ASC 606 performance obligations, document the Section 48E domestic content and energy community adders, reserve for workmanship warranty per kilowatt, and survive the post-Section 25D residential market in 2026.
