Description

Photovoltaic module concentrating device

Technical Field

The invention relates to the technical field of photovoltaic components, in particular to a photovoltaic component light concentrating device.

Background technique

Single solar cells cannot be used directly as power sources. To use them as power sources, several single cells must be connected in series or parallel and tightly sealed into modules. Solar cell modules (also called solar panels) are the core and most important part of solar power generation systems. Their function is to convert solar energy into electrical energy, or to store it in batteries, or to drive loads. Since the output voltage of single solar cells is low, and the electrodes of unpackaged batteries are easily detached due to environmental influences, a certain number of single cells must be sealed into solar cell modules in series or parallel to avoid corrosion of battery electrodes and interconnects. In addition, packaging also avoids battery fragmentation and facilitates outdoor installation. The quality of packaging determines the service life and reliability of solar cell modules. Solar cell modules are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. They have the characteristics of long service life and strong mechanical resistance to external pressure. The structural forms of conventional solar cell modules are as follows: glass shell structure, bottom box module, flat module, and full-glue sealed module without cover.

The existing device cannot use the concentrator to increase the concentrating area, cannot maximize the absorption of solar energy by the photovoltaic panel, has low efficiency, and cannot remove dust adhering to the concentrator. Excessive dust affects the concentrating effect of the concentrator, and the practicability of the device is poor.
