Solar power generation has been supported by the state, which provides paving and regional subsidies. Of course, it has also attracted the attention of countless people. To understand the details of solar power system, we must first understand which equipment the solar power system is composed of, and then explain the details of which equipment the solar power system is composed of.
There are two types of solar power systems, usually with energy storage devices. One is to generate electricity directly on the Internet. At present, 99% of the most popular is the direct power sales to the grid, and 1% is the power generation system with energy storage equipment.
The following is the content introduction
Solar panel
Solar controller
Solar inverter
Solar grid connection and solar off-grid
Solar panel is the core component of solar power system. The purpose of solar panels is to convert the light energy of the sun into electric energy. Solar panel is one of the most important components of solar power system. Its efficiency and service life depend on whether the solar cell has service value.
The solar controller is composed of special processor CPU, electronic components, display screen, control switch power tube, etc. The most popular controller is MPPT and PWM controllers.
Solar system output voltage is usually 12VDC, 24VDC and 48VDC. In order to supply power to 220VAC appliances, the DC generated by the solar power system must be converted into AC energy, so DC-AC inverter must be used
Solar grid connection refers to the direct access of solar panel array + combiner box + inverter to the grid and solar off-grid refers to solar panel array + combiner box + controller + Battery + inverter (controller and inverter can be said to be an integrated machine). The difference is whether there is an energy storage part. Generally speaking, grid connection means selling electricity to make money, while energy storage is standby electricity, or the main power equipment in urban power areas cannot be installed, such as border posts, forest monitoring and some industrial and commercial roofs. Banks and hospitals have corresponding requirements for solar power generation, so they can install power generation and energy storage equipment.
