研究目的
To investigate the optimum cleaning frequency of PV modules cleaning through monitoring the soiling loss and to compare between the Annual Cleaning Cost and the Annual Energy Losses Cost to meet the optimized Cleaning rate with the minimum Energy Losses and Cost.
研究成果
The optimum cleaning interval is found to be approximately 8 days, which minimizes the total annual cost by balancing the cleaning cost and energy losses cost. The study recommends considering tilted angle, site altitude, and environmental conditions for individual cases.
研究不足
The study's findings are based on simulations and may vary with actual environmental conditions, tilt angles, and site altitudes. The cleaning cost and energy tariff assumptions may also affect the applicability of the results.
1：Experimental Design and Method Selection:
The study uses PV*SOL software for dynamic simulation of photovoltaic systems and curve fitting to model the relationship between cleaning intervals and energy losses.
2：Sample Selection and Data Sources:
The study simulates the system without and with soiling effects at different intervals (3, 10, 15, 23, and 30 days).
3：List of Experimental Equipment and Materials:
PV*SOL software is used for simulation.
4：Experimental Procedures and Operational Workflow:
The system is simulated without soiling to get maximum annual generated energy, then with soiling at different intervals to calculate energy losses.
5：Data Analysis Methods:
Curve fitting is used to model the relationship between cleaning intervals and energy losses, and optimization is performed to find the optimum cleaning interval.
