  Thank you. Quoting the relevant section below: 14. Photovoltaic Requirements. All low-rise residential buildings shall have a photovoltaic (PV) system meeting the minimum qualification requirements as specified in Joint Appendix JA11, with annual electrical output equal to or greater than the dwelling’s annual electrical usage as determined by Equation 150.1-C: kWPV = (CFA * A) / 1000 + (NDwell * B) Where: kWPV = kWdc size of the PV system CFA = Conditioned floor area NDwell = Number of dwelling units A = Adjustment factor from Table 150.1-C B = Dwelling adjustment factor from Table 150.1-C (I'm not going to try to copy the table into this comment.) I also found this document digging around recent additions to the public docket site: http://docketpublic.energy.ca.gov/PublicDocuments/18-BSTD-01/TN222679_20180222T142828_Initial_Study_and_Proposed_Negative_Declaration_for_the_2019_En.pdf http://docketpublic.energy.ca.gov/PublicDocuments/18-BSTD-01... It says "The specific minimum size of the system is based on the size of the building and number of dwellings and can vary between 2 and 7 kilowatts output per dwelling..." Which is less specific, but it's nice to see upper and lower minimum capacity requirements without having to consult a table.
