Abstract

An economic evaluation tool for solar power selfconsumption system with battery storage was implemented. This tool calculates output power of solar system and battery storage system to evaluate reduced purchased electric power by installing self-consumption system. System control methods can also be evaluated with this tool to confirm the value it claims. As a result, indexes like Return of Investment and self-consumption rate can be calculated according to system conditions and system control candidates. It is expected that a balanced system design can be obtained, in the phase of system planning, by using this tool to address concerns of equipment investor and solution provider. In this paper, several evaluation results were presented as use cases of this tool, where a self-consumption system with system control methods was tested for a system of 250 kW load consumption.
