What model building code years does SolarAPP+ enforce?

To satisfy the greatest number of jurisdictions, SolarAPP was initially built to the 2017 National Fire Protection Association (NFPA) 70 National Electrical Code (NEC) and the 2018 I-Codes (International Residential Code, and International Building Code) developed by the International Code Council (ICC). Updates are underway to accommodate jurisdictions that utilize the 2020 NEC. As additional code updates are made (such as the 2021 I-Codes and 2023 NEC), these will also be incorporated as options for jurisdictions to select.
