The requirements for distributed energy resources (DERs) are rapidly evolving, including those for DERs using solar photovoltaic (PV) systems. This second installment in a series on evolving standards details the code and additional safety requirements for the connection of direct current PV circuits to inverters.
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 ).
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.
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 ). PV systems have requirements that span multiple Code articles, so technicians need to navigate throughout the NEC to install code-compliant PV and ESS systems.
Outside of the NEC, technicians need to be cognizant of the fire codes their jurisdictions enforce and how PV systems are regulated within those codes. The most common fire codes are NFPA 1, Fire Code and ICC’s International Fire Code (IFC). These codes typically impact the physical layout of PV modules on the roof of a building.
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.
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.

Sometimes two is better than one. Coupling solar energy and storage technologies is one such case. The reason: Solar energy is not always produced at the time energy is needed most. Peak power usage often occurs on summer afternoons and evenings, when solar energy generation is falling. Temperatures can be hottest during these times, and people ...
High-Temperature Performance. The power temperature coefficient is the amount of power loss as cell temperature increases.
