1. Photovoltaic modules (solar photovoltaic panels): a certain number of single-chip cells are sealed into solar cell modules in series and parallel. The quality of module packaging determines the service life and reliability of solar cell modules. Components need regular maintenance and cleaning to improve photoelectric conversion efficiency.
2. Inverter: the current generated by the module is DC current, which needs to be converted into AC for use. This function is what the inverter does. Inverters can be divided into single-phase and three-phase, which need to match with the actual power generated by components. Generally, the power of three-phase is greater than that of single-phase. If 15kw components are installed, a 17kw three-phase inverter shall be installed correspondingly.
PV benefits:
The clean and low-carbon of the whole photovoltaic power generation industry chain has further amplified this repair effect.

With the continuous progress of technology, the energy consumption of battery, module production and power station construction has become lower and lower, only about 1.3kwh per watt. That is to say, in an area with sufficient light in Northern Shaanxi, enough clean electricity can be generated to "offset" the energy consumption in the early stage in only about one year, and then continue to contribute to low-carbon sustainable development for more than 20 years.
