The future of solar PV array is to attach them to battery storage to deliver greater energy resilience, energy security and energy savings.
Battery Storage Technology
Overview of Technology: Storage batteries are the heart of all off-grid and back-up wind/PV or inverter electrical systems. Their function is to balance the outgoing electrical requirements with the incoming power supply. They offer a reliable source of electricity which can be used when solar or wind power is not available. Batteries are able to provide short term power output many times higher than the charging source output.
