The act excludes solar pool heating systems from that definition."

# California AB 2249 (20112012) — Solar Water Heating and Efficiency Act of 2007.

The Solar Water Heating and Efficiency Act of 2007 makes findings and declarations of the Legislature relating to the promotion of solar water heating systems and other technologies that reduce natural gas demand and defines terms for purposes of the act. The act requires the Public Utilities Commission (PUC) to evaluate data available from a specified pilot program, and, if it makes a specified determination, to design and implement a program of incentives for the installation of 200,000 solar water heating systems, as defined, in homes and businesses throughout the state by 2017. The act requires the PUC, in consultation with the State Energy Resources and Conservation Commission and interested members of the public, to establish eligibility criteria for the solar water heating systems receiving gas customer funded incentives. The act requires the PUC to establish conditions on those incentives. The act defines a solar water heating system as a solar energy device that has the primary purpose of reducing demand for natural gas through water heating, space heating, or other methods of capturing energy from the sun to reduce natural gas consumption in a home, business, or any building receiving natural gas sold or transported for consumption in this state and that meets or exceeds the eligibility criteria. The act excludes solar pool heating systems from that definition.
