What are the key codes for solar PV & battery storage?

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 ).

How do you classify a solar power kit?

In determining the classification of the solar power kit (SKU# 96535), we are guided by General Rule of Interpretation (GRI) 3 in determining its classification because the items within the solar power kit are classifiable under two or more separate headings.

What tax credits are required for solar projects?

This relates to both the Section 48/48E Investment Tax Credit (ITC) and the Section 45/45Y Production Tax Credit (PTC). IRS requires that structural construction components like steel and rebar foundation posts for solar projects are 100% U.S. manufactured.

What is the rate of import duty on wind generators?

In the United States, wind powered generator sets (HT SUS 8502.31) attract 2.5 % rate of import duty. Gear boxes used for such sets (HT SUS 8483.40.70) are levied with 3.9 % rate of import duty, whereas ball bearings without integral shafts (HT SUS 8482.10.50) attract 9 %.

How do fire codes affect energy storage systems?

Fire codes also regulate the use and location of energy storage systems (ESS). Chapter 15 of NFPA 855 provides requirements for residential systems. In particular, ESS spacing, unit capacity limitations, and maximum allowable quantities (MAQ) depending on location. PV systems also have structural requirements and codes associated with them.

Are PV systems regulated by fire codes?

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.
