Beneficial Effects of Nano Hydrophobic Coatings for Solar Photovoltaic Modules in Dusty Environment

摘要

In this paper, we propose and experiment the application of self-cleaning Nano coating on solar panels. We have measured an important increase of water droplet contact angle on a Nano coated surface. We found beneficial effects on light transmittance and Open Circuit Voltage (Voc) for the photovoltaic modules. Experimentally, we have shown a higher Transmission coefficient (T) in case of treated glass. In addition, from Thermal Camera analysis, we have shown that the Nano coated Photovoltaic module became cooler and cleaner comparatively to untreated module.
