International Code Council releases 2021 solar energy provisions

The International Code Council worked with the National Association for Fire Protection (NFPA) to publish the 2021 International Solar Power Supply (ISEP)† The document brings together all the solar energy provisions of the 2021 International Codes (I-Codes) and the NFPA 70 National Electrical Code (NEC)2020, making it streamlined and easy to use in the field.

“The 2021 ISEP consolidates current solar system code requirements into a single, comprehensive, cost-effective publication,” said Mark Johnson, executive VP and director of business development at the Code Council. “All building, electrical, fire, plumbing, energy and mechanical requirements related to solar are at your fingertips.”

The ISEP was created to provide a comprehensive tool for the design, installation and management of both solar thermal (or solar heating and cooling) and photovoltaic (PV) systems. The document provides information on relevant standards and provides additional resources such as solar permitting forms, checklists, solar site entry points, and links to the U.S. Department of Energy’s solar site. With the growing demand for energy efficiency and sustainability, the ISEP will greatly benefit the industry by providing a single, organized source of solar thermal and photovoltaic safety codes in one publication.

“The 2020 edition of NFPA 70, National Electrical Code (NEC), plays a key role in the design and installation of solar photovoltaic systems. This proud partnership with the Code Council allows NFPA to continue to provide key information and knowledge that designers, installers and operators need to deliver safe solar projects,” said Erik Hohengasser, electrical engineering chief at NFPA.

“One of the key aspects of the 2021 ISEP is that it brings together key code sources for both photovoltaic and solar thermal systems,” said Shawn Martin, VP of technical services at ICC Evaluation Service. “Users benefit from the latest code provisions and the latest reference standards – all in one book.”
