Implication

Randomized trial compares cleaning methods to improve photovoltaic efficiency in dusty environments, indicating optimal maintenance strategies.

Key Points

The study aims to evaluate the effectiveness of different cleaning methods on the efficiency of photovoltaic modules under varying dust conditions.
Conducted a field-based experiment with 15 monocrystalline silicon PV modules arranged in a triplicate design.
Applied controlled laterite dust at densities of 10, 20, and 30 g/m2 to simulate different soiling conditions.
Monitored module performance using calibrated systems and analyzed data with two-way ANOVA and regression modeling.
PV efficiency decreased systematically with increased dust density, with uncleaned modules showing significant performance degradation.
Automated robotic cleaning achieved the highest efficiency and energy yield across all dust levels (p < 0.001).
Regression analysis confirmed a strong linear relationship between dust density and efficiency loss (R² > 0.99).
