Moreover, used solar panels will soon outnumber other landfill debris if PV panel installations continue at the present rate. PV systems utilize 40 % of the world''s tellurium, 15 % of its silver, and a large amount of semiconductor-grade quartz, indium, zinc, tin, and gallium, although they produce just 3 % of the world''s power [9] .
In recent years, the average conversion efficiency of solar panels has increased from 15% to more than 21%. Since two main factors determining the efficiency of solar panels are: the efficiency of photovoltaic cells (based on silicon type and cell design), and total panel efficiency (based on configuration, panel size, and cell layout).
Intensity is determined by the angle and location of the sun in the sky. The inclination and intensity of the sun are influenced by your region also, which overall influences the efficiency of solar panels.
The effect of solar illuminance (or intensity) on a photovoltaic panel has been examined. Illuminance is synonymous to light intensity. Illuminance is directly proportional to light intensity per square of the distance between the source of light and object.
Operations like monitoring and controlling the performances of solar panels influence their efficiency and help in retaining it for longer periods. Also, carrying out operations to improve the overall conditions of solar panels positively influences efficiency at large. 7. Temperature
Five light intensity values are quickly measured each time, which are the light intensity values of four corners and their centers of the photovoltaic panel, and then, the average value is the light intensity of the photovoltaic panel surface.
The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity. Therefore, it can be known that the greater the light intensity, the better the power generation performance of the solar cell. 1. Introduction
