From the press release (emphasis added):
Moving to cut energy use in new homes by more than 50 percent, the California Energy Commission [CEC] today adopted building standards that require solar photovoltaic systems starting in 2020. The building energy efficiency standards, which are the first in the nation to require solar, will reduce greenhouse gas emissions by an amount equivalent to taking 115,000 fossil fuel cars off the road.
I've read a few different articles about the new standards, and spent some time reviewing the standard itself, but I have one big question:
For a specific home, how will the builder determine the exact capacity of solar system that must be installed?
An infographic from the CEC gives a figure of $9,500 for the initial cost, but what is this based on? Will the amount of solar required vary depending on the size of the house, number of bedrooms, location or location type (urban, rural, etc), or some other factor?
