A Method to Develop Web-Based Performance Estimation for Grid-Connected Photovoltaic Systems: A Case Study in Dong Nai Province, Vietnam

This article presents a method to develop a web-based performance estimation for grid-connected photovoltaic system in Vietnam. It's called PVcall. The solar radiation data and simulation models are linked to the web interface. In addition, a yield model of a web-based performance model based on the parameters of the commercial PV module (PV) and the performance rate (PR) was developed. All data including solar radiation, PV parameters and PR were input into the yield model to estimate the final yield of a photovoltaic system. In addition, the solar radiation and the final yield of the PV system are visually displayed in the form of a dashboard in the web interface. The result also shows the number of PV modules and areas required for the installed system. In addition, the accuracy of the system has been proven by comparing it with the commercial software.
