English Abstract
This study aims to practically verify the effect of some environmental factors on the efficiency of solar cells, these factors that affect the performance of the cells have been tested, including the accumulation of dust on the cell surfaces, water droplets, remnants of birds, in addition to the shadow caused by surrounding buildings or trees or so.
This study was done on the roof of building, by putting two solar panels fixed on an iron stand then used the necessary equipment to carry out the measurements.
The results of the study showed that the accumulation of dust and dirt on the surface of PV modules had a significant impact on reducing the electrical power generated by solar cells, the percentage of reduction in output power equal (8.80%).
so the solar cells should be cleaned regularly (daily or weekly) depending on the severity of the weather conditions.
Also the water droplets had a positive impact on the efficiency of solar cells, where it reduced the temperature of cells and thus generating more power affecting the efficiency in terms of power generation.
The improvement that notice in power output equal to (5.9%).
The shading factor that partially blocked the sunlight from reaching the surface of the panels facing the sun had the highest influence of the efficiency of the PV cells and therefore the cells have to be placed in appropriate locations to allow for maximum efficiency.
The highest percentage of reduction in power by three-quarters shading equal to ( 92.6%).
One of the environmental factors that affected the performance of the PV cells are remnants of birds that partially blocked radiation from the sun.
The power reduction equal to ( 7.4%).
The results suggests that end users of the PV panels should not overlook the importance of periodic cleaning of the solar cells to obtain the desired efficiency.
