NEC Solar and Storage Regulations Explained
Innovative and brand new solar markets have changed the photovoltaic (PV) systems across the country in recent decades. Technological advancements and fire protection objectives
This article highlights the key codes and some of the top sections contractors working with solar PV and battery storage should be familiar with. The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code (NEC).
The National Electrical Code (NEC) has been updated every three years to align with the changes in the photovoltaic (PV) industry, which has been significantly impacted by technological advancements and fire protection objectives. Innovative and brand new solar markets have led to these changes in PV systems across the country. The new NEC regulations are published in a book format.
Another Code article that will be nearly universally referred to during the design and installation of PV systems is Article 705, Interconnected Electric Power Production Sources. This article covers the requirements for all power production sources interconnecting together, so it isn't unique to solar.
Additional Code articles that impact PV installations include 691, Large-Scale Photovoltaic (PV) Electric Supply Stations; Article 706, Energy Storage Systems; Article 480, Storage Batteries; and the entirety of Chapters 1 through 4, with Article 250 and Article 300 being commonly referenced.
