Residential photovoltaic systems are easy to deploy and can reduce electricity costs while also serving as an on-site power source during disasters; however, the number of installations has fallen to about half of its peak level. In snowy regions, reduced power generation efficiency in winter and potential damage and degradation due to snow loads are of concern. Snow-melting by heating and mechanical snow removal increase maintenance costs. Therefore, this study aims to improve winter conversion efficiency and reduce maintenance costs by using a snow-accretion-prevention structure with a hydrophobic surface treatment. As a fundamental evaluation, ice adhesion strength was measured using a vertical pull-off apparatus, and its temperature dependence was investigated.
