The solar panel is the core part of the solar power generation system. The function of the solar panel is to convert the schematic diagram of the solar energy grid-connected power generation system into electrical energy, and the output DC power is stored in the battery. Solar panels are one of the most important components in solar power systems, and their conversion rate and service life are important factors in determining whether solar cells are useful. Component design: Designed in accordance with International Electrotechnical Commission IEC: 1215:1993 standard, using 36 or 72 polycrystalline silicon solar cells in series to form 12V and 24V various types of components. The module can be used in various household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants.
Characteristics of raw materials: Cell: It adopts high efficiency (16.5% or more) monocrystalline silicon solar chip package to ensure sufficient power generation of solar panels. Glass: Low-iron tempered suede glass (also known as white glass) with a thickness of 3.2mm, with a transmittance of more than 91% in the wavelength range of the solar cell spectral response (320-1100nm), for infrared light greater than 1200 nm Has a higher reflectivity. The glass is also resistant to radiation from the sun's ultraviolet light, and the light transmittance does not decrease. EVA: A high-quality EVA film with a thickness of 0.78 mm, which is coated with an anti-UV agent, an antioxidant and a curing agent, is used as a sealing agent for solar cells and a connecting agent with glass and TPT.
It has high light transmittance and anti-aging ability. TPT: The back cover of the solar cell - the fluoroplastic film is white, reflecting the sunlight, so the efficiency of the component is slightly improved, and because of its high infrared emissivity, the operating temperature of the component can also be lowered. Helps improve the efficiency of components. Of course, the fluoroplastic film firstly has the basic requirements of aging resistance, corrosion resistance, and air resistance required by the solar cell packaging material. Border: The Aluminum Alloy frame used has high strength and strong resistance to mechanical shock. It is also the most valuable part of solar power systems. Its role is to convert the solar radiation capacity into electrical energy, or send it to the battery for storage, or to drive the load.
