Double-glass photovoltaic module capable of melting snow

Abstract

The invention discloses a double-glass photovoltaic module capable of melting snow. The photovoltaic module comprises a battery piece formed by serially connecting multiple batteries through a tin-coated copper strip, and the battery piece is a generating unit of a module; high-transmittance glass is packaged at a front and a back of the battery piece through adhesive films, the battery piece andthe high-transmittance glass at the front and the back thereof form the double-glass photovoltaic module, and a lead line of the battery piece formed by serially connecting multiple batteries is usedas the module lead line; the photovoltaic module further comprises an electric-heating wire which is arranged on the high-transmittance glass at the back of the battery piece and connected with the module lead line through a junction box controller; the junction box controller controls the electric-heating wire to heat the double-glass photovoltaic module, thereby eliminating the molten snow. Thedouble-glass photovoltaic module disclosed by the invention is excellent in performance and has an automatic snow-melting function; the accumulated snow on the module surface can be molten at any timewhen snowing, the generating quantity of the module is increased, and the work of manually cleaning the accumulated snow is saved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic components, and relates to a double-glass photovoltaic component capable of melting snow. Background technique [0002] At present, single-glass modules are most commonly used in power stations. Such modules have the following problems in snowy days: 1) Snowmelt cannot be eliminated, especially in the Northeast, which is covered by snow throughout the winter, resulting in the failure of photovoltaic modules to generate electricity, and the power generation of the entire power station drops. Many; 2) At present, the power station uses manual snow removal on components, which is inefficient and difficult to completely remove snow. When the frequency of snowfall is high, the operation and maintenance cost of the power station will greatly increase. Contents of the invention [0003] In view of the defects or deficiencies in the above-mentioned prior art, the purpose of the present invention is...
