The function of the solar panel is to convert the sun's light energy into electrical energy and then output direct current and store it in the battery. Solar panels are one of the most important components in solar power generation systems. Their conversion rate and service life are important factors that determine whether solar cells have value. Product Description:
Our company's solar panels are designed in accordance with the requirements of the International Electrotechnical Commission:: standard, using 3 or single/polycrystalline silicon solar cells connected in series to form various types of components. This component can be used in various household photovoltaic systems, independent photovoltaic power stations and grid-connected photovoltaic power stations.
Features of raw materials:
Cells: Use high-efficiency (. or above) monocrystalline silicon solar chip packaging to ensure sufficient power generation from the solar panels.
The glass is made of low-iron tempered suede glass (also known as white glass), with a thickness of 3., and within the wavelength range of the solar cell spectral response (3-), the light transmittance reaches above, and it has a greater light transmittance for infrared light greater than High reflectivity. This glass can also withstand the radiation of solar ultraviolet rays, and the light transmittance does not decrease.
Solar panels: Use a high-quality film layer with a thickness of . It has high light transmittance and anti-aging ability.
Solar panel: The fluoroplastic film covering the back of the solar cell is white and reflects sunlight, thus slightly improving the efficiency of the module. Because of its high infrared emissivity, it can also reduce the cost of the module. The operating temperature is also conducive to improving the efficiency of the components. Of course, this fluoroplastic film first has the basic requirements of aging resistance, corrosion resistance, and airtightness required by solar cell packaging materials.
Frame: The aluminum alloy frame used has high strength and strong resistance to mechanical impact.

Comparison between solar cells and other batteries
A solar cell is a device that converts light energy (mainly sunlight) into electrical energy. The principle is the photovoltaic effect, that is, the built-in electric field of the junction causes the photogenerated carriers to separate and reach both sides of the junction to generate a photovoltage. When connected to an external circuit, the power output of the solar cell is related to the intensity of light. The stronger the light, the stronger the light intensity. The stronger the power output. Generally, solar cells have the advantages of high charge absorption capacity, long cycle life, good rechargeability, and no need for maintenance.
Lead-acid batteries: Most electric vehicles today are equipped with lead-acid batteries, because lead-acid batteries are low-cost and cost-effective. This battery is rechargeable and can be used repeatedly. But under the same capacity, the battery is heavier and larger and has a shorter life.
Ni-MH batteries: have higher specific volume, single cell life, and high current charge and discharge characteristics than lead-acid batteries. However, once the nickel-metal hydride battery series battery pack is overcharged, the single battery separator will melt, causing the entire battery pack to rapidly fail.
Lithium-ion battery: high energy, high power, small self-discharge, no memory effect, good cycle characteristics, fast discharge, high efficiency, wide operating temperature range, no environmental pollution, etc. However, when lithium-ion batteries are used in electric vehicles, a series battery pack must be used. The complexity of the series battery pack is far greater than the protection circuit of a single battery, and its material cost is also greatly increased.
The dangers of littering used batteries
Batteries contain a large amount of heavy metals, such as zinc, lead, cadmium, mercury, manganese, etc. According to expert tests, one button battery can pollute cubic meters of water. One AA battery rotted in the ground can make one square meter of land lose its use value. If used batteries are mixed with domestic waste, after the batteries rot, heavy metals such as mercury, cadmium, lead, and nickel will dissolve and contaminate groundwater and soil, and then penetrate into fish and crops, destroying the human living environment and threatening human health. . If people are poisoned by mercury, they will suffer from central nervous system diseases, with mortality rates as high as 10%. Cadmium in used batteries is designated as a carcinogen.
During the solar installation process, please pay attention to the following items:
Do not install solar cell modules in shaded places such as trees and buildings. Do not go near open flames or flammable materials. The assembly structure should be able to adapt to environmental requirements. Please choose appropriate materials and anti-corrosion treatments. Use reliable methods to install components. If the components fall from a high altitude, they may cause damage or interfere with the safety of people and property. Do not disassemble, bend or hit the components with hard objects. Avoid stepping on the components.
Use spring washers and flat washers to lock the battery panel assembly on the bracket. Ground the panel assembly in an appropriate manner based on the site environment and the state of the mounting bracket structure.
The battery panel assembly has a pair of male and female waterproof plugs. When making a series electrical connection, the + pole plug of the previous assembly must be connected to the pole plug of the next assembly. The output circuit must be properly connected to the device. Do not short-circuit the positive and negative poles. Make sure there are no gaps between the joints and the insulating joints. If there are gaps, sparks or electrical shock may occur. Check the lifting structure frequently to see if it is loose. If necessary, retighten the parts. Check the connection status of each wire, ground wire and plug.
Frequently wipe the component surface with a soft cloth. If you really need to replace components (generally not required during the year), you must choose the same type and model. Do not touch moving parts of cables or connectors with your hands. If necessary, use appropriate safety equipment. (Insulated tools or gloves, etc.)
When repairing components, please cover the front surface of the component with an opaque object or material, because the component will generate high voltage when exposed to sunlight, which is very dangerous. Quality Assurance Components are guaranteed for a period of years. The power attenuation during the year shall not exceed, and the power attenuation during the year shall not exceed.
