The answer is no, off grid solar power plant require batteries to store electricity. If the grid power isn't available and batteries are out of equation too.
[pdf] Battery Energy Storage Systems, or BESS, are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries and can be used to balance the electric grid, provide backup power and improve grid stability.
[pdf] In Mongolia, the National Power Transmission Grid has secured a loan from the Asian Development Bank (ADB) to install the country’s first large-scale advanced battery energy storage system (BESS).
[pdf] Self-contained and incredibly easy to deploy, they use proven vanadium redox flow technology to store energy in an aqueous solution that never degrades, even under continuous maximum power and depth of discharge cycling. Our technology is non-flammable, and requires little maintenance and upkeep.
[pdf] In Tārgale, Latvia's largest wind energy producer SIA "Utilitas Wind" opens the first large-scale electricity storage battery system in Latvia with a total power of 10 MW and a capacity of 20 MWh.
[pdf] Sila Nanotechnologies, Inc. is an American battery manufacturer that produces using nanoengineered silicon particles. The company creates battery materials to replace traditional graphite with a silicon-dominant composite material, in order to increase energy density. The company is building a factory in in state.
