California Is Putting Solar Water Heating Back on the Incentive Map
Nov 04, 2026SoCalGas currently offers rebates for qualifying OG-100 solar thermal collectors used in multifamily and commercial water-heating applications, while South Coast AQMD has expanded its GO ZERO Phase 2 program to include zero-emission solar water heating. For California property owners, contractors, engineers, and developers, these programs create new reasons to evaluate solar thermal as part of a broader hot-water and energy strategy. SunEarth can help project teams review system requirements, collector…
