The bandgap of the PV reduces as the temperature of the solar cell rises, increasing short-circuit current and a drop in open-circuit voltage. The performance of a photovoltaic module is mainly influenced by the cell's semiconductor material, irradiation intensity, operating temperature, and wind velocity.
Most of the correlations usually include a reference state and the corresponding values of the pertinent variables. The electrical performance is primarily influenced by the type of PV used. A typical PV module converts 6-20% of the incident solar radiation into electricity, depending upon the type of solar cells and climatic conditions.
Dust accumulation lowers the performance efficiency of the photovoltaic (PV) module by up to 40 %. The power and efficiency of the PV module are reduced by 0.5 % and 0.05 % for every 1 °C rise in ambient temperature. The optimum tilt angle of the module is determined by mathematical analysis and empirical correlations.
Photovoltaic modules (Figure 2) are interconnected solar cells designed to generate a specific voltage and current. The module's current output depends on the surface area of the solar cells in the modules. Figure 2. A flat-plate PV module. This module has several PV cells wired in series to produce the desired voltage and current.
The correlation coefficient (R) value for ambient temperature was 96 % with a confidence interval of 95 %, indicating that the module efficiency of the solar PV linearly varies with ambient temperature. Yadav and Bajpai evaluated the performance of a 5 kW rooftop solar PV plant located in Northern India.
