Research on optimal configuration of distributed photovoltaic energy storage system for profitability improvement

The abundant and idle roof resources in rural areas provide a good prerequisite for the promotion and construction of household photovoltaic (PV). Based on this background, this paper combs and analyzes the operation modes of rural household PV system, constructs a cost-benefit calculation model of household PV, calculates the economic benefits of four household PV operation modes through calculation examples. The research results can provide reference for economic evaluation and promotion of rural household PV system investment.
