It is necessary to exclude the cause of glue. The epoxy resin used for packaging solar glue panels needs to be prepared in a certain proportion. Different manufacturers and different batches of glue have differences;
p>Epoxy Has the resin dried completely before being exposed to sunlight? For example, if you take a piece of mud and expose it directly to the sun, large cracks will appear. But if you wait until it dries completely and then expose it to the sun, the cracks will be much better.
Solar panels are divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon.
According to the packaging method: epoxy board, laminate (glass lamination, PET lamination, ETFE lamination), different processes, unit prices are also different
Epoxy board is relatively low. It is generally used in lamps and toys. LThis product is compact, mainly reflected in its small size and low power. The unit price ranges from 1 to 15 yuan.
Glass and aluminum frame solar panels range from 1W to over 300 watts. , the price is also different, the general unit price is 3-5 yuan/watt
PET and ETFE cards, the unit price ranges from 5-8 yuan,
More , it can be folded or folded. The unit price of folding products is generally higher than that of ordinary products. I have been in the industry for 3 years. If you have any further questions, send me a private message
