PvBenefit is an economic assessment tool based on the entire life cycle cost of various components in a photovoltaic system. Its advantage lies in calculating the full life cycle cost of each photovoltaic component for different component prices and service lives to obtain a more accurate present value of the total cost and investment payback period prediction. Users can customize input parameters such as interest rate, inflation rate, photovoltaic panel area, photovoltaic component price and service life, total service life of the grid-connected photovoltaic system, regional annual average radiation, electricity price, and photovoltaic panel conversion efficiency to obtain reliable prediction results. This figure shows a case study of input settings (this case uses the price unit of RMB), as well as the predicted total cost and investment payback period results. When users input information about components, please ensure that the input information is consistent with the format in the picture. Necessary information includes component name, total initial purchase price, and service life. You can increase or decrease the component types. Finally, please ensure to use the JSON string format and use double quotes instead of single quotes.
