Abstract

The invention provides a double-surface photovoltaic assembly system which comprises a plurality of photovoltaic assemblies. The double-surface photovoltaic assembly system is characterized in that the front surface and the back surface of the photovoltaic assembly are respectively provided with a front glass layer and a back glass layer; a cell panel is arranged between the front glass layer andthe back glass layer; the front glass layer is provided with a transparent reflecting layer; the photovoltaic assembly is obliquely arranged; the inclination angles of the photovoltaic assemblies aresame; and the distances between the photovoltaic assemblies are same. According to the double-surface photovoltaic assembly system, double glass layers are adopted; and sunlight can be simultaneouslyreflected to the back surface of another photovoltaic assembly, thereby improving sunlight utilization rate and power generation efficiency.

Description

technical field [0001] The invention belongs to the field of photovoltaics, in particular to a double-sided photovoltaic module system. Background technique [0002] Photovoltaic modules are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy and send it to the battery for storage, or to promote the load to work. Photovoltaic modules are composed of solar cells or a combination of solar cells of different specifications cut by a laser cutting machine or a steel wire cutting machine. Since the current and voltage of a single solar cell are very small, we first connect them in series to obtain a high voltage, and then connect them in parallel to obtain a high current, and then output it through a diode. And they are packaged on a stainless steel, aluminum or other non-metal frame, the glass on the top and the back plate on the back are installed, fil...
