6 FAQs about [New Standards for Photovoltaic Energy Storage]
Are photovoltaic solar energy systems safe?
The safe and reliable installation of photovoltaic (PV) solar energy systems and their integration with the nation’s electric grid requires timely development of the foundational codes and standards governing solar deployment.
Does California need a photovoltaic system?
With many factors increasing the need for reduced energy usage, lower emissions, and less dependency on fossil fuels, California’s latest energy code has implemented stronger requirements for photovoltaic (PV) systems, with a large percentage of new buildings now requiring not only PV but also battery storage.
Are there exceptions to PV and battery storage requirements?
Exceptions There are exceptions to these PV and battery storage requirements. Sometimes even code writers can see that a requirement just doesn’t make sense or that another code, due to safety requirements, may take precedence. These are the types of exceptions you will see here.
Should a building have a larger PV system?
There could be a benefit to provide a larger PV system, since there is available roof area, if it is cost effective to power more of the building using PV, or there could be benefits to selling power back to the utility. Providing more battery storage may also provide the facility with more flexibility in how they use it.
Do rooftop solar PV array circuits need to be controlled?
Rooftop solar PV array circuits must be controlled to reduce potential shock hazards to firefighters. To meet this requirement, the rapid shutdown section of the NEC provides multiple ways to meet the requirements based on the location of the circuit in relation to the PV array.
What are the cost parameters for a commercial Li-ion energy storage system?
Commercial Li-ion Energy Storage System: Modeled Cost Parameters in Intrinsic Units Min. state of charge (SOC) and max. SOC a Note that, for all values given in per square meter (m2) terms, the denominator refers to square meters of battery pack footprint. The representative system has 80 kWh/m2.
