The composition and structure of household solar photovoltaic power generation system is what?

Home solar photovoltaic power generation system is mainly composed of solar panels, solar controller, maintenance-free lead-acid battery and ac/dc inverter is the main part. One of the core components are photovoltaic battery and controller. The role of each component in the system is

use solar photovoltaic power generation system is mainly composed of solar panels, solar controller, maintenance-free lead-acid battery and ac/DC inverter. Core component is the photovoltaic battery and controller. Is the function of each component in the system: solar panel: solar panel is the core part of the solar system, was a high value part of the solar system. Its function is to convert the sun's radiation ability into electrical energy, or store it into the battery, or promote work load. Material composition cell: adopting the high efficiency ( 16. More than 5%) Monocrystalline silicon solar encapsulation, ensure the solar panels have enough capacity. The thickness of the glass: 3. 2 mm low iron tempered suede glass ( Also known as the white glass) In the solar spectral response wavelength range ( 320 - 1100 nm) Light transmittance is greater than 91%, to more than 1200 nm infrared light with high reflectivity. Glass can resist the sun's ultraviolet radiation at the same time, the light transmittance is not reduced. EVA: high quality EVA film layer, thickness of 0. 78 mm, adding anti-uv agents, antioxidants and curing agent, used for solar battery sealant and connection with glass and thermoplastic polyurethane. It has high light transmittance and aging resistance. TPT: fluorine plastic thin film solar cell rear cover is white, can reflect sunlight and thus slightly improve the efficiency of the module. Because of its high infrared emissivity, it can also reduce the operating temperature of module, but also to improve the efficiency of the module. First of all, of course, this kind of fluorine plastic film is solar battery encapsulation materials needed for the ageing resistance, corrosion resistance, airtight etc. Basic requirements. Frame: used for aluminum alloy frame with high intensity, mechanical shock resistance ability. Solar controller: solar controller's function is to control the working state of the whole system, prevent the battery overcharge and over discharge. In difference in temperature big place, qualified controller should also has temperature compensation function. Other additional features, such as light control and time control switch should be the optional features of the controller.
