What is solar photovoltaic power generation
Solar photovoltaic power generation is a new type of energy generation using photovoltaic effect. Using the absorption of sunlight to generate electricity, photovoltaic panels absorb solar energy into direct current, which is then converted by an inverter into usable alternating current for home use. The current period into the commercial solar energy, refers to solar photovoltaic power generation.
Whether it is used independently or grid-connected power generation, photovoltaic power generation system is mainly composed of solar panels (components), controllers and inverters, which are mainly composed of electronic components and do not involve mechanical parts, so photovoltaic power generation equipment is extremely refined, reliable and stable long life, easy installation and maintenance.
Second, the difference between photovoltaic power generation and solar power generation
Photovoltaic power generation is a small class of solar power generation, solar power generation includes photovoltaic power generation, photochemical power generation, photoinduction power generation and photobiological power generation, and photovoltaic power generation is only one of the solar power generation. Usually the folk solar power generation often refers to solar photovoltaic power generation, referred to as photoelectric.
Among them, solar power generation and solar photovoltaic power generation and solar thermal power generation, solar thermal power generation and photovoltaic power generation are different:
1, the power generation principle and device are different
Photothermal power generation is through the heat collection device to drive the steam turbine power generation, is the way of heat to electricity, the main component is the collector or device. Photovoltaic power generation is the use of semiconductor photovoltaic effect to directly convert light energy into electricity, the basic component solar panels, is the way of light to electricity.
2, the scope of use is different
The electricity generated by solar solar thermal power generation has better compatibility with traditional thermoelectric and hydropower, and is suitable for large-scale development. In addition, due to the higher requirements for lighting conditions, solar thermal power generation is more suitable for areas with good lighting conditions. The photovoltaic power generation device is relatively simple, the lighting requirements are relatively low, more suitable for miniaturization development, so it is also more suitable for distributed utilization.
3, different in the specific application
Photovoltaic power generation has formed industrialization, the use of technology is more mature, suitable for large-scale promotion and use. The solar thermal power generation is still mainly in the scientific research demonstration stage, the cost is also at a very high level, and large-scale application needs time.
