What are the requirements for large PV power plants?

Large PV power plants (i.e., greater than 20 MW at the utility interconnection) that provide power into the bulk power system must comply with standards related to reliability and adequacy promulgated by authorities such as NERC and the Federal Energy Regulatory Commission (FERC).

Are solar PV systems electrical equipment?

See NEC Articles 100, 690, 691, 705 and other applicable articles for all pertinent definitions. Accordingly, solar PV systems, including the placement, positioning and securement of photovoltaic modules, panels and arrays, and their associated components and all electrical wiring, are electrical equipment under the State Electrical Code.

Do I need to meter a photovoltaic system?

It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.

Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

Are PV storage systems safe?

Storage systems in PV plus storage settings call for many overlapping safety standards and precautions, particularly those that apply to working on DC wiring, and bring a set of technology-specific new considerations.

Do I need a license to install solar photovoltaic systems in Minnesota?

Answer: Yes. A new law effective July 1, 2023, requires companies that contract with residential homeowners to install solar photovoltaic (PV) systems on homes in Minnesota be licensed as a residential building contractor or remodeler.
