ЭЛЕКТРОТЕПЛОВАЯ СИСТЕМА ПРОТИВООБЛЕДЕНЕНИЯ СОЛНЕЧНОГО МОДУЛЯ

The paper describes and demonstrates the electro-thermal de-icing system using the thermal conductivity effect in solids and designed to remove snow and ice from the front surface of the solar panel both at low temperatures (below zero degrees centigrades) and heavy mixed precipitations. We show the known and being developed alternative approaches for cleaning the operating surface of solar panels from ice and snow and considered the significant need for the proposed system application. The location and functions of key components of the presented de-icing system are practically optimized to increase the efficiency in case of precipitation fallout on its front surface. The design of the multilayer structure of de-icing system is shown and described in details. We present a computer simulation model with building graphs with showing the efficiency of the proposed electro-thermal system in various environmental conditions. We also demonstrate the successful experimental field testing data of operating electro-thermal de-icing system of solar panel in South Ural climatic conditions. We also show that the electro-thermal de-icing system of solar panel powered from batteries, may increase the time of uninterrupted operation of solar panel during the mixed precipitations.
