Double-sided photovoltaic power generation device

Abstract

The invention provides a two-sided photovoltaic power generator, comprising a two-sided photovoltaic power generating component and a light reflecting element; one side of the two-sided photovoltaic power generating component facing to sunshine is positive face while the other side is back face; the light reflecting element is arranged at the back face of the two-sided photovoltaic power generating component, and the light reflecting element is provided with a light reflecting face to reflect sunray to the back face of the two-sided photovoltaic power generating component; the light reflecting face is a convex face towards the two-sided photovoltaic power generating component. Through arranging the light reflecting element at the back face of the two-sided photovoltaic power generating component and reflecting sunray to the back face of the two-sided photovoltaic power generating component by the light reflecting face of the light reflecting element, the light utilization efficiency is improved, the power generation efficiency is improved, and the economic benefit is further increased.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a double-sided photovoltaic power generation device. Background technique [0002] Conventional photovoltaic power generation modules are single-sided crystalline silicon modules, which can only receive sunlight on one side for power generation. The same installation area has low light utilization efficiency and low power generation efficiency. The double-sided photovoltaic power generation module can receive sunlight on the front and back to generate electricity on both sides, but the power generation on the back of the existing double-sided photovoltaic power generation module depends on the natural ground reflection light for power generation, the ground will absorb most of the light, and the light utilization efficiency Low, poor power generation efficiency, and poor economy. Contents of the invention [0003] The object of the present invention is to solve the above...
