How To On-grid Solar System Work?
On-grid solar system is a system that converts solar energy into electrical energy and transmits this electrical energy directly to the power grid. The following is its detailed working principle:
On-grid solar system is mainly composed of solar cell modules, On-grid inverters, data acquisition systems, data exchange equipment, operation display equipment, and monitoring equipment. These components work together to achieve efficient solar energy conversion and On-grid power generation.
(1) Solar energy conversion: Solar cell modules are the core of a On-grid solar system. They convert sunlight into DC power through the photoelectric effect.
(2) DC to AC: Since the power grid uses AC, the DC power generated by the solar cell modules needs to be converted into AC power through a On-grid inverter. The On-grid inverter not only has a conversion function, but also has an automatic phase and voltage tracking device that can perfectly cooperate with the tiny phase and voltage fluctuations of the power grid to ensure the stability and safety of On-grid power generation.
(3) On-grid power generation: The converted AC power is transmitted to the power grid through the grid access point to provide electricity for end users. When solar power generation is insufficient, the power grid will provide power to support the operation of the system and ensure the stability of power supply.
On-grid solar energy systems can be divided into two types: reversible On-grid and irreversible On-grid, depending on whether the photovoltaic system transmits power to the high-voltage grid through the transformer in the power supply area. According to the different grid access points, it can be divided into two types: user low-voltage side grid-connected (mainly for self-use) and boosted On-grid (power can be sold online).
In summary, the On-grid solar energy system converts solar energy into DC power through solar cell modules, and then converts DC power into AC power through On-grid inverters and transmits it to the grid. This system not only has the advantages of no pollution, no noise, and no consumption of fossil energy, but also has low cost and broad application prospects.
