Solar photovoltaic panels performance improvement using active self-cleaning nanotechnology of SurfaShield G

摘要

Solar cleaning techniques were used to improve the performance of photovoltaic panels. A new nano material SurfaShield G, TiO2 based, was used as innovative solution for effective photovoltaic panel surface cleaning by spraying onto the 150 W photovoltaic panel, the results were compared to the uncoated panel with the same features. The properties of the material were tested in a specialized laboratory and showed excellent photocatalytic and resistivity for dust and super-hydrophilicity, the transmittance of the coated surface was improved even without any dust accumulation. In the harsh climate conditions at the Levant area, the Kingdom of Jordan, the output of the coated and uncoated panels was monitored for three months to show the performance improvement by calculate the additional power produced from the coating, the findings showed a 20% and 2.3% improvement in the maximum power and efficiency, respectively.(c) 2021 Elsevier Ltd.
