Battery Cabinet Photovoltaic Technical Requirements

Which building types require a photovoltaic (PV) system?

All newly constructed building types specified in Table 140.10-A, or mixed occupancy buildings where one or more of these building types constitute at least 80 percent of the floor area of the building, shall have a newly installed photovoltaic (PV) system meeting the minimum qualification requirements of Reference Joint Appendix JA11.

What are the solar PV requirements for mixed occupancy buildings?

The solar PV requirements apply to buildings where at least 80 percent of the total floor area (conditioned or not) is made up of building types listed in Table 140.10-B, including mixed occupancy buildings. These include: What are the Requirements for Battery Storage Systems?

Can a nonresidential building be excluded from a battery storage system?

Four exceptions can exclude nonresidential buildings from the battery storage system requirements: Single-tenant buildings with < 5,000 square feet of conditioned floor area (CFA). For multi-tenant buildings, the battery storage system energy and power capacities are based on tenant spaces > 5,000 square feet of CFA

What is the required battery storage system size?

The required battery storage system size is based on the solar PV system size determined for building types listed in Table 140.10-B, including mixed-occupancy buildings. The total capacities of a battery storage system shall be no less than those calculated from the equations above.

Does a battery storage system need a rated usable energy capacity?

No. For compliance with the Energy Code the rated usable energy capacity of the battery storage system in kWh must be used for Equation 140.10-B - PDF. The usable capacity is the battery energy storage capacity in kWh that a manufacturer allows to be used for charging and discharging.

Does a building need a battery storage system?

All buildings that are required by Section 140.10 (a) to have a PV system shall also have a battery storage system meeting the minimum qualification requirements of Reference Joint Appendix JA12. The rated energy capacity and the rated power capacity shall be not less than the values determined by Equation 140.10-B and Equation 140.10-C.
