Standards, codes, and implementation have been cited as major impediments to widespread use of photovoltaics (PV) within electric power systems. Effectively interconnecting the high penetration of solar electricity envisioned by the DOE SunShot Initiative requires careful technical attention to ensuring compatibility with the grid.
The following codes and standards relate to high penetration PV.
UL 1741 requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems.
Adopted in all 50 states, the National Electrical Code (NEC) is the benchmark for safe electrical design, installation, and inspection to protect people and property from electrical hazards.
The IEEE SCC21 1547 Series of Interconnection Standards is a benchmark milestone for both the IEEE standards consensus process and a model for developing further national standards dedicated to the ongoing success of our nation's electric power system.
Published by IEEE, the National Electrical Safety Code (NESC) sets the ground rules for practical safeguarding of persons during the installation, operation, or maintenance of electric supply and communication lines and associated equipment.
