1. The composition of solar power supply system
The solar power generation system is composed of solar battery packs, solar controllers, and storage batteries (groups). If the output power is AC 220V or 110V and needs to be complementary to the mains, it is also necessary to configure an inverter and a smart switch for the mains.
1. Solar cell arrays are solar panels
This is the core part of the solar photovoltaic power generation system, and its main function is to convert solar photons into electrical energy to promote the work of the load. Solar cells are divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells. The monocrystalline silicon battery is more durable than the other two types, has a longer service life (generally up to 20 years), and has higher photoelectric conversion efficiency, which makes it the most commonly used battery.
2. Solar charge controller
Its main job is to control the state of the entire system, while protecting the battery from overcharging and overdischarging. In places where the temperature is particularly low, it also has a temperature compensation function. ?
3. Solar deep cycle battery pack
As the name implies, the battery stores electricity. It mainly stores the electric energy converted from solar panels. Generally, it is a lead-acid battery, which can be recycled for many times.
In the entire monitoring system. Some equipment needs to provide 220V, 110V AC power, and the direct output of solar energy is generally 12VDc, 24VDc, 48VDc. Therefore, in order to provide power to 22VAC and 11OVAc devices, a DC/AC inverter must be added to the system to convert the DC power generated in the solar photovoltaic power generation system into AC power.
2. The principle of solar power generation
The simplest principle of solar power generation is what we call a chemical reaction, that is, the conversion of solar energy into electrical energy. This conversion process is the process by which solar radiation energy photons are converted into electrical energy through semiconductor materials, usually called the "photovoltaic effect", and solar cells are made using this effect.
