Cleaning frequency of the solar PV power plant for maximum energy harvesting and financial profit

Cleaning frequency of the solar PV power system plays a major role in energy harvesting. This paper proposed an optimized cleaning for plants. The objective is to maximize harvesting and increase financial profit. technique tested roof top grid connected 20 kW plant Cairo, Egypt. Experimental results are collected one year throw period from January 2021 December based on real time monitoring under regular every fifteen days. data used deriving formula find optimal cells. can be any different operating conditions. Therefore, detect losses due dust accumulated surfaces panels. model this research verified by comparison between generated photovoltaic cost (water workers) case manual cleaning, taking into consideration various conditions though whole study.
