PVT roof snow melting system with heat transfer fluid

Abstract

The invention relates to a PVT roof snow melting system with heat transfer fluid (10), which enables the melting of snow and / or ice accumulated on the surface of photovoltaic panels by heating the panel surface through the heat generated either from the sunlight absorbed by the panels or from the resistance element (15) powered by the electricity produced from solar photons The system transfers the high heat collected by heat transfer pipes (13) located at the back of the panel to a heating element (30) through an intermediate transfer pipe (14), thereby providing ambient heating. Invention is characterized in that the PV (12) surface is heated either directly by solar energy or by a hating element (15) powered by the electrical energy generated from solar energy, thus melting the snow or ice accumulated or likely to accumulate on the PV (12) surface. The excess heat on the PV (12) surface is transferred through the heat transfer pipes (13) and the intermediate transfer pipe (14) to the indoor heating element (30), enabling indoor temperature rise. Electrical energy produced by the PV (12) is transmitted from the junction box (16) through connection cables (70) to the charge controller (40), power converter (50), and energy storage unit (60) for storage and / or grid use. The system contains a phase‐changeable heat transfer fluid with solid particles sized between 10 and 200 nanometers, including colemanite, borax, Al₂O₃, SiO₃, CuO, TiO₂, SiL, boron carbide, szaybelite, and boron, which enable rapid heat transfer through evaporation in combination with the absorbed heat.
