To amend the Internal Revenue Code of 1986 to provide an increased tax credit for combined photovoltaic and thermal technology.

This bill increases tax credits for solar energy systems that generate both electricity and heat from a single panel (combined photovoltaic and thermal technology). It directly affects homeowners and businesses installing qualifying systems certified to meet specific efficiency standards (65% combined peak efficiency under IEC/UL 61730 and ISO 9806 standards). The key change adjusts the tax credit percentages: raising the maximum credit from 30% to 45% for the first tier, 26% to 41% for the second, and 22% to 37% for the third tier. These higher credits apply to systems installed after June 1, 2022.
