What is NHSP and CSI?
The California Solar Initiative is the general name for the governmental support on the solar projects. However, CSI is also used to distinguish between existing home programs and new home programs, which are slightly different. The CSI programs (PBI and EPBB) are for existing homes and commercial projects and are currently (May ’07) handled by the utility companies. The program for new homes is called New Solar Homes Partnership Program (NHSP), and is handled personally by CEC. Why? That is not something we can answer.
