Hydrophobic sol-gel based self-cleaning coating for photovoltaic panels
Maintaining photovoltaic performance from soiling issues using manual cleaning is costly and tedious which has been a major concern in deploying this technology. Therefore, a soiling mitigation technique with self-cleaning properties such as hydrophobic coating is effective to minimize performance d...
