Solar and Storage Conversations From the Field

Insights and experiences from solar PV, energy storage, and building and safety professionals, offering valuable lessons from the field.

As solar PV and energy storage installations surge across jurisdictions throughout the country, all stakeholders involved are responsible for ensuring that these systems are installed in a safe and code-compliant manner. The landscape of clean energy adoption is undergoing a profound and transformative shift, and this growth underscores the vital importance of a shared understanding and education among our authorities having jurisdiction (AHJs) and clean energy practitioners. 

In late 2023, IREC gathered a panel of seasoned professionals to share their insights and experiences and describe what is really happening in the field of solar PV and battery energy storage systems (BESS). During this dynamic discussion, we explored critical aspects of safe installations, from system disconnects and labeling to roof setbacks and safety requirements for BESS. While not an exhaustive list, these topics represent critical components of safe installation where significant confusion remains. The candid conversation highlights the importance of continued communication and trust between the solar and energy storage industry and AHJs. 

As you listen in, you’ll gain a wealth of inspiring insights and knowledge which will enable you to better navigate the dynamic clean energy landscape and shape the future in your jurisdiction. It’s where expertise, collaboration, and innovation converge to redefine safety, sustainability, and progress.
