A solar panel is a device that absorbs sunlight and converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. It is one of the important components in the solar power generation system, and the solar cell is the determining factor. Important factors in conversion rate and service life.

01
Tempered glass
Its function is to protect the main body of power generation (such as battery cells). There are requirements for the selection of light transmittance. One is that the light transmittance must be high (generally more than 91%), and the other is ultra-white tempered treatment
02
EVA
It is used to bond and fix tempered glass and the main body of power generation (such as battery cells). The quality of the transparent EVA material directly affects the life of the component. EVA exposed to the air is prone to aging and yellowing, thus affecting the light transmittance of the component, thus affecting the In addition to the quality of EVA itself, the power generation quality of components
03
Solar cell
The main function is to generate electricity. The mainstream power generation market is crystalline silicon solar cells and thin film solar cells, both of which have their own advantages and disadvantages. Crystalline silicon solar cells have relatively low equipment costs, but high consumption and cell costs. However, the photoelectric conversion efficiency is also high, and they are more suitable for generating electricity under outdoor sunlight.
04
Junction box
It protects the entire power generation system and acts as a current transfer station. If a component is short-circuited, the junction box automatically disconnects the short-circuited battery string to prevent the entire system from burning out. The most critical thing in the junction box is the selection of diodes. Depending on the type of cells in the module, the corresponding diodes are also different.
05
Aluminum alloy frame
Protect laminated parts and play a certain sealing and supporting role
06
Backsheet
The function of the back plate is to seal, insulate and waterproof
07
Silicone
Sealing function, used to seal the junction between components and aluminum alloy frames, components and junction boxes.

2. Regularly check whether the metal brackets of solar panels are corroded, and paint the brackets regularly for anti-corrosion treatment. The square array bracket must be well grounded.
3. During use, the photoelectric parameters and output power of the solar panels should be tested regularly (such as 1 to 2 months) to ensure the normal operation of the solar panels.
4. During use, the packaging and connection joints of the solar cell modules should be checked regularly (such as 1 to 2 months). If there is any leakage of water in the package, discoloration of the cells, loose joints, disconnection, corrosion, etc., repair them in time. or replace.
