Photovoltaic energy

Photovoltaic energy is based on photovoltaic effect to convert solar radiation energy into electric energy. Photovoltaic energy has the advantages of no pollution, no noise, low maintenance cost and long service life, and has developed rapidly in recent years.

system composition

Photovoltaic energy system generally includes solar cells or components, charge and discharge control system (or inverter) and load control. Solar cells are devices that convert solar radiation energy into electric energy based on photovoltaic effect.

Affected by weather, load and other factors, it is difficult for solar cells to obtain stable DC output, so most solar systems need to store energy through storage batteries before supplying power to the outside world. The main function of the charge-discharge controller is to control the charge-discharge process of the battery in the system and prevent the battery from being damaged due to overcharge or overdischarge. The function of the inverter is to convert the low-voltage DC output by the battery into the alternating current required by the electrical appliance.

Grid-connected power generation mode is to convert DC power generated by solar cell array into AC power through inverter and transmit it to power grid without battery. Comparatively speaking, grid-connected power generation is cheaper and completely pollution-free. The grid-connected inverter used in grid-connected power generation system has automatic phase and voltage tracking device, which can well cooperate with the tiny phase and voltage fluctuation of the power grid and will not affect the power grid.
