Remove photovoltaic support

Technical Field

The utility model belongs to the technical field of new energy power generation equipment, and particularly relates to a movable photovoltaic bracket.

Background

Photovoltaic power generation is a technology that uses the photovoltaic effect of a semiconductor interface to directly convert light energy into electrical energy. The solar energy power generation system mainly comprises three parts of a solar panel (assembly), a controller and an inverter, wherein the main parts are composed of electronic components. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then the solar cell module is matched with components such as a power controller and the like to form the photovoltaic power generation device. The single solar cell cannot be directly used as a power supply, and a plurality of single cells must be connected in series and parallel and tightly packaged into a component as the power supply. Solar cell modules (also called solar panels) are the core part of and the most important part of a solar power generation system. The solar energy is converted into electric energy, or is sent to a storage battery for storage, or the load is pushed to work.

And photovoltaic panel assemblies are power generation devices that generate direct current when exposed to sunlight, and consist of thin solid photovoltaic cells made almost entirely of semiconductor materials (e.g., silicon). The existing photovoltaic panel assembly is generally fixed outdoors through a fixed frame body, and proper inclination angles and setting intervals are set according to local illumination conditions, so that optimal power generation efficiency is obtained.
