The raw materials for the production of EVA film are mainly rubber particles. This material does not produce harmful gases. However, there are chemical substances in the production process, namely glue. It is recommended to carry gas. mask, if the company is not qualified to take care of you, you will still have to choose another company with your health first and your job second.
Photovoltaic solar panels are generally not damaged by hail.
The glass panel is made of tempered glass, which has a certain strength and can withstand ordinary hail.
Normal strength hail cannot be broken. Qualified photovoltaic panels must pass a strength test and be able to withstand the impact of hail 25 mm in diameter (about the size of a pigeon's egg) and 23 meters per meter. second in speed. Ordinary hailstonesThey are not as direct and fast.
It is rare for ordinary glass to be damaged by hail. The surface of the solar panel is tempered glass, which is very hard, 4-5 times that of ordinary glass. Ordinary hail will not damage it.
Detailed information:
Photovoltaic solar panel material:
1. Tempered glass: Its function is to protect the main body of power generation (such as battery cells). The selection requirements for light transmission are:
2. glass and the main body of power generation (such as battery cells), the quality of the transparent EVA material directly affects the service life of the EVA component exposed to the air which is prone to aging and yellowing, thereby affecting the transmission of light. the component.
This affects the power production quality of the component in addition to the EVA itselfe. In addition to quality, the module manufacturer's lamination process also has a great impact. The bonding degree of EVA is not up to standard and the bonding strength between EVA and tempered glass and backplane is insufficient, this will cause premature aging of EVA and affect the service life. life of the module.
3. Cells: The main function is to produce electricity. Both crystalline silicon solar cells and thin film solar cells have their own advantages and disadvantages. Relatively high equipment costs. Low, but the consumption and cost of cells are high, but the photoelectric conversion efficiency is also high.
Thin film solar cells are more suitable for generating electricity under light from the outdoor sun. is high, but the battery consumption and cost are very low, but the phot conversion efficiencyoelectricity is more than half of that of crystalline silicon cells, but the low light effect is very good, and can also generate electricity under ordinary light, for example. like solar cells in calculators.
