Photovoltaic cell panel capable of removing accumulated snow and ice

Abstract

The invention discloses a photovoltaic cell panel capable of removing accumulated snow and ice. The photovoltaic cell panel comprises a plurality of photovoltaic cells, which are arranged in the sameplane and are adjacent to each other; a first glass plate covering the photovoltaic cells, wherein the first glass plate has a first side facing to the photovoltaic cells and a second side having an anti-reflection coating extending along the whole second side to prevent sunlight from being reflected so as to improve photovoltaic property of the photovoltaic cell panel; and an electric heating network array, which is arranged between the first glass plate and the photovoltaic cells and extends along the first side of the first glass plate, wherein electric heating networks are arranged in parallel in the array, and the electric heating networks are thermally coupled to the first glass plate. The problems to be solved and the beneficial effects are that when the photovoltaic cell panel forms an angle with the level, the electric heating networks heat the first glass plate to enable snow and ice to slide off the photovoltaic cell panel; the electric heating networks are thermally separated from the photovoltaic cells through a low-thermal-conductivity transparent layer; and the photovoltaic cell panel is high in yield rate.

Description

technical field [0001] The invention relates to a photovoltaic cell panel capable of clearing accumulated ice and snow. Background technique [0002] Photovoltaic solar panels have been developed to convert sunlight directly into electricity. Even in cold climates, photovoltaic solar panels are effective as long as they are exposed to sunlight, but they do not produce much electricity when they are covered with ice and snow, so in In cold climates, when snow and ice accumulate on top of the solar panels, the overall efficiency of the solar panels is reduced and snow and ice must be cleared, but using electric heating elements placed directly on top of the solar panels to help melt off all the snow and ice takes a lot energy, the overall efficiency is very low. Contents of the invention [0003] The technical problem to be solved by the present invention is that when the photovoltaic solar cell panel is at an angle to the horizontal, the electric heating grid heats the fir...
