Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a storage and charging device applied to photovoltaic building integrated power generation and grid connection. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of independent operation and grid-connected operation. At the same time, solar photovoltaic power generation systems are classified into two types: centralized, such as large-scale northwest ground photovoltaic power generation systems, and distributed (with >6MW as the boundary), such as photovoltaic power generation systems on the roofs of industrial and commercial enterprise factories and residential rooftop photovoltaic power generation systems.

[0003] Photovoltaic panels are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since they have no moving parts, they can operate for long periods of time without causing any loss. Simple photovoltaic cells can provide energy for watches and calculators, while more complex photovoltaic systems can provide lighting for houses and power the grid. Photovoltaic panels can be made into different shapes and the components can be connected to generate more electricity. In recent years, photovoltaic panels have been used on rooftops and building surfaces, and have even been used as part of windows, skylights or shading devices. These photovoltaic facilities are usually called building-attached photovoltaic systems;

[0004] Traditional photovoltaic building integrated power generation and grid-connected storage and charging equipment does not have the function of cleaning photovoltaic panels during use. In order to ensure working efficiency, photovoltaic panels are directly installed outdoors. However, when fallen leaves or dust accumulates on the top of the photovoltaic panels, it will affect the overall working quality of the photovoltaic panels. Moreover, since most photovoltaic panels are installed in high positions, it is inconvenient for staff to clean them, which brings trouble to the staff's use. Utility Model Content
