| Summary: | <p><em>A novel experimental method for power efficiency loss is presented in this paper. It is used to quantitatively determine the impact of dust deposition on the PV power generation panel. To determine the selection range of unknown parameters in the </em><em>experiment process</em><em>, a photovoltaic </em><em>panel</em><em> </em><em>with </em><em>five</em><em> </em><em>collected</em><em> dust </em><em>samples</em><em> (</em><em>Toner (C)</em><em>, Soil,</em><em> Cement</em><em> </em><em>(</em><em>Ca</em><em>O</em><em>,</em><em> </em><em>SiO<sub>4</sub></em><em>)</em><em>, </em><em>Gypsum (</em><em>Ca<sub>2</sub>SO<sub>4</sub>.2H<sub>2</sub>O</em><em>)</em><em>, and</em><em> Sand (</em><em>AL<sub>2</sub>O<sub>3</sub>, SiO<sub>4</sub></em><em>)</em><em>) is designed. According to experimental </em><em>results</em><em>, the </em><em>extinction</em><em> coefficient for the </em><em>five</em><em> pollutants are </em><em>recorded</em><em>. Eventually, the </em><em>impact</em><em> of</em><em> dusts on</em><em> the </em><em>results </em><em>is </em><em>proofed</em><em> by </em><em>repeating in two continuous days of same</em><em> conditions. </em><em>The results show that the proposed process has a high effect on the reduction of output power (62% to 96%), decrease of irradiance (34% to 93%) and increase of output power due to increase of tilt angle as a doubling of power except toner. </em><em></em><em>The experimental and calculated results are in agreement. The results show that non-uniform distribution of dust deposit pollutants on the photovoltaic panel significantly reduces the power output.</em></p><p><em><br /></em></p><p><strong>Received: 09 January 2023 </strong></p><p><strong>Accepted: 06 February 2023</strong></p><p><strong>Published: 16 February 2023</strong></p> |
