New solar panels (
New
New) are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The main materials of most solar panels are Silicon, but its production costs are so high that it cannot be widely and commonly used in large quantities. Compared with ordinary batteries and recyclable rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products

New
New) Tempered glass is used for protection There are requirements for the selection of light transmittance for the main body of power generation (such as battery cells).
The light transmittance must be high (generally

Ultra white tempered treatment

New)
Used to bond and fix tempered glass and the main body of power generation (such as battery cells). The quality of the transparent material directly affects the life of the component. It is easy to age when exposed to the air. Yellowing, thus affecting the light transmittance of the module, thereby affecting the power generation quality of the module. In addition to the quality of the module itself, the lamination process of the module manufacturer also has a great impact. For example, if the bonding degree is not up to standard,
Insufficient bonding strength with tempered glass and backplane will cause premature aging and affect the life of the components.
New
New) The main function of cells is to generate electricity. The mainstream in the power generation market are crystalline silicon solar cells and thin film solar cells. Both have their own advantages and disadvantages. Crystalline silicon solar cells,
/>The equipment cost is relatively low, but the cost of consumption and cells is high, but the photoelectric conversion efficiency is also high, so it is more suitable to generate electricity under outdoor sunlight. Thin-film solar cells have relatively high equipment costs, but low consumption and battery costs. However, the photoelectric conversion efficiency is more than half that of crystalline silicon cells, but the low-light effect is very good. It can also generate electricity under ordinary light, such as on a calculator. of solar cells.

The function is as above, mainly bonding and packaging the power generation body and the back plate
New
New) The function of the back plate is sealing, insulation, and waterproofing (generally Materials such as
and
must be resistant to aging. Most component manufacturers provide a one-year warranty
. Tempered glass and aluminum alloy are generally no problem. The key lies in whether the backplane and silicone can meet the requirements. .)
New
New) Aluminum alloy protective laminate plays a certain sealing and supporting role
New
New) The junction box protects the entire power generation system and acts as a current transfer station. If the module is short-circuited, the junction box will automatically disconnect the short-circuited battery string to prevent burning of the entire system. The most critical thing in the junction box is the selection of diodes. According to the type of battery cells in the module, the corresponding diode will not be the same. Same
New
New) Silicone sealing function is used to seal the junction between components and aluminum alloy frames, components and junction boxes. Some companies use double-sided tape and foam to replace silica gel. Silica gel is commonly used in China. The process is simple, convenient, easy to operate, and the cost is very low.
