What are the components of the solar photovoltaic system?
Frame: aluminum alloy frame with high strength, strong resistance to mechanical impact. Is also the most valuable part of home solar power. A device for converting direct current into alternating current. Since the solar cells and batteries are DC power, while the load is AC load, the inverter is essential. The inverter can be divided into independent operation inverter and grid connected inverter. The independent operation of the inverter is used for the independent operation of the solar cell power generation system, for independent load power supply. Grid connected photovoltaic power generation system for grid connected operation. The inverter can be divided into square wave inverter and sine wave inverter according to the output wave type. The square wave inverter has the advantages of simple circuit, low cost, large harmonic component, and the utility model can be used for a system with a few hundred watts and a low harmonic requirement. Sine wave inverter is expensive, but can be applied to various loads.
TPT: on the back of the solar battery cover of fluorine plastic film is white, the sun has reflection function, so the efficiency of components increased slightly, and because of its high infrared emissivity, can reduce the working temperature of the component, but also conducive to improve the efficiency of the component. Of course, the fluorine plastic film with the first solar cell packaging materials required for aging, corrosion resistance, air permeability and other basic requirements.
EVA: a high quality EVA film with a thickness of 0.78mm, which is made of UV resistant agent, antioxidant and curing agent, is used as a sealing agent for solar cells and a bonding agent between glass and TPT. High light transmittance and aging resistance.
Photovoltaic system is composed of solar cell array, battery, charge and discharge controller, inverter, AC distribution cabinet, automatic solar tracking system, automatic solar module dust removal system and other equipment. The equipment is in the light (either sunlight or other light generated by the light) case, battery to absorb the light, the two ends of the cell appeared heterocharge accumulation, namely "photo voltage", which is "photovoltaiceffect". Under the effect of the photovoltaic effect, both ends of the solar cell produce electromotive force, which converts light energy into electrical energy, which is an energy conversion device. Silicon solar cells are generally divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells three
