Modeling and Simulation of Output Characteristics of Photovoltaic Cells Under the Ecological Environment of Hainan
Investigating output characteristics of photovoltaic(PV)cells in different environments is of great significance for determining maximum power point and improving PV systems efficiencies.In this work a modified mathematical model for PV cells was established and used to simulate output characteristics of PV cells under different light intensities and temperatures,as well as at different irradiation angles according to the specific environment in Haikou area.the depend-ence law of PV cells with light intensity and temperature and the optimal installation angle for PV panels in Haikou were then determined based on the simulation results.
