In this article, we have studied the variation of the electrical performance characteristics of photovoltaic modules under the effect of dust. We have installed four modules of different technologies on the CERER site (Centre for Study and Research on Renewable Energies) for a year without being cleaned and each month we note their characteristics. The four technologies used are mono crystalline, polycrystalline, amorphous and thin film CdTe.
The results showed that dust has more impact on thin film technology with a degradation of 68% of its power and less impact on amorphous which experienced a 29% loss in power.
