What is a solar photovoltaic roof?
Typical solar photovoltaic (PV) panel or thermal systems consist of the solar or thermal panels and their BOS equipment. Building-integrated photovoltaic (BIPV) roof covering systems consist of solar elements integrated into the roofing material.
What is the minimum array area requirement for a solar PV inverter?
Although the RERH specification does not set a minimum array area requirement, builders should minimally specify an area of 50 square feet in order to operate the smallest grid-tied solar PV inverters on the market.
What is a photovoltaic module?
A photovoltaic (PV) module is a packaged, and connected photovoltaic solar cells assembled in an array of various sizes. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.
What CEC provisions apply to a PV system?
