Solar Batteries

Solar batteries are energy storage components designed to operate as part of an integrated solar power system, storing locally generated solar energy for later use rather than functioning as standalone grid-scale storage assets. Solar batteries are examined in the context of electrification systems where solar generation, power conversion, and storage work together to support electrified facilities, fleet depots, charging infrastructure, and microgrid-enabled sites.

Most solar batteries today use advanced lithium-ion chemistries - particularly lithium iron phosphate (LFP) - which provide high cycle life, safety, and efficiency. These systems enable daily self-consumption, backup power during outages, and cost savings through time-of-use energy management. They also play a role in emerging virtual power plants (VPPs), where distributed batteries are aggregated to provide grid services.

While distinct from the larger BESS systems used at solar farms and substations, solar batteries are part of the same energy storage continuum -scaling from residential to utility level. Together, they represent a cornerstone of electrification, grid modernization, and energy resilience.
