Description

Self-cleaning photovoltaic panels and photovoltaic power generation systems

technical field

The utility model relates to a solar photovoltaic power generation panel, in particular to a photovoltaic power generation panel with a self-cleaning function.

Background technique

A solar panel module is a power generation device that collects heat when exposed to sunlight and converts light energy into direct current electricity. It is composed of thin solid photovoltaic cells almost entirely made of semiconductor materials (such as silicon). Since there are no moving parts, it can be operated for a long time without any wear and tear. Simple photovoltaic cells power watches and computers, and more complex photovoltaic systems light homes and power the grid. Solar panel components can be made into different shapes, and the components can be connected to generate more electricity. Solar panel components are used on roofs and building surfaces, and are even used as part of windows, skylights or shading devices. These photovoltaic facilities are usually called building-attached photovoltaic systems.

Solar cell modules are placed outdoors for a long time, full of wind, sand, ups and downs, and now the environment is seriously polluted, basically all of which are putty. These impurities prevent the solar panels from absorbing sunlight and reduce the working efficiency of the batteries. The absorption of solar energy gradually weakens, and it is easy to cause partial burnout, which affects the normal operation of the solar panels, so regular cleaning and cleaning are required. However, for the cleaning of solar panels, scrubbing with hard objects can easily scratch the surface glass, resulting in uneven refraction Occurs and affects power generation.

The existing cleaning methods are mainly wind sweeping or mechanical sweeping. The cleaning effect of wind sweeping is very poor for oily particles, or dust particles adhered to the surface of the battery panel by rain or snow fog. Mechanical dust removal can easily lead to scratches on the surface glass plate, which will affect the light transmittance and refractive index, and then have a negative impact on power generation.

In the prior art, the Chinese patent (application number: CN201620456597.5, announcement number: CN205792430U, titled "dust-proof self-cleaning protective cover applied to solar photovoltaic modules") discloses the following technical features: including protective covers, solar photovoltaic modules, Self-cleaning device, the protective cover is arranged above the solar photovoltaic module, and a self-cleaning device is arranged above the protective cover, and the self-cleaning device includes a cleaning strip, a brush, a motor, a telescopic rod, an in-position sensor, and a controller. The brush is arranged on the left side of the cleaning strip, the telescopic rod is connected to the right side of the cleaning strip, the left edge and the right edge of the protective cover are provided with in-position sensors, and the in-position sensors and the motor are connected with the controller. The design of the protective cover of the utility model reduces the adhesion of dust, and at the same time, a self-cleaning device is arranged on the top, which can realize regular cleaning of the dust on the cover plate of the protective cover, which is convenient to clean and avoids cleaning the tempered glass above the solar cell module.

This method is to use a mechanical cleaning device to clean the surface of the solar power generation panel. When the cleaning brush cleans the dust particles, it will drive the dust to rub against the surface of the glass plate, thereby forming scratches and affecting the light transmission and refractive index.
