Battery energy storage and solar systems are revolutionizing the nation’s electrical infrastructure and creating a strong commercial and consumer interest, with the number of residential battery energy storage system (ESS) installs during the first quarter of 2018 increasing nine-fold over 2017 Q1 figures, according to PV Magazine. That number equaled totals from the previous three quarters.

This means that first responders may well encounter emergency calls involving ESS or photovoltaics (PV).
