At the present time, the average cost of a solar battery storage system ranges between $500 to $800 per usable kWh, depending on the product, region, and installation complexity.

The project integrates 87kWp solar panels, a 50kW hybrid inverter, a 100kWh all-in-one battery energy storage system (BESS), a 37kW water pump, and a 15kW residential load—creating a self-sufficient energy solution for the farm.
