As for household solar energy, maybe a lot of heat is known. Now many households in rural areas also use solar water heaters. So, what is the principle of the generator for household solar energy? What are its functions? Let's talk about the principle of the solar powered generators for homes and the role of each component of the system.
Principle of solar powered generators for homes
Household power generation system is generally composed of photovoltaic array composed of solar cell modules, solar charge and discharge controller, battery pack, off grid inverter, DC load and AC load. If the output power supply is AC 220V or 110V, an inverter is also required. The photovoltaic array converts solar energy into electric energy under the condition of light, and supplies power to the load through the solar charge and discharge controller, while charging the battery pack; When there is no light, the battery pack supplies power to the DC load through the solar charging and discharging controller, and the battery also supplies power directly to the independent inverter, which inverts the current to supply power to the AC load.
Compared with other energy utilization technologies, solar power generation has incomparable advantages, mainly in the following aspects:
1： The solar energy resources are not in danger of being exhausted, and the resources are widely distributed with little geographical restrictions; Therefore, solar energy is very rich in resources, which can be said to be the energy from nature. It is very powerful.
2： Silicon, the main material of solar cells, is rich in raw materials; No mechanical rotating parts, no noise, good stability; This makes people feel more comfortable in the process of use, and there is no need to worry about noise pollution, environmental protection and health.
3： The system is a component, which can be quickly installed anywhere without pollution, and is completely clean (except for the battery). The installation is also very convenient. Generally, we can learn to install by ourselves after we buy it.
4： The maintenance is simple and low. This is also the reason why people like to use solar energy. It can be seen that it brings more comfort and convenience to people's lives.
