The reasons for inadequate sealing of photovoltaic modules
Poor Quality of Sealant
After curing, the sealant may crack or delaminate, directly or indirectly damaging the sealing of the photovoltaic module's cell. Some low-quality sealants, due to poor raw materials and failure to meet basic requirements, may even pose safety risks.Problems with the Application of Sealant
The amount of sealant applied and the method of application can both affect the sealing effectiveness. For example, insufficient sealant, the presence of air bubbles in the sealant, or improper cleaning of the bonding surface can all result in inadequate sealing.Poor Performance of the Sealant
The silicone sealant used for photovoltaic modules must meet strict performance standards, particularly in terms of weather resistance, and resistance to high and low temperatures. If it does not meet the long-term operational requirements of photovoltaic systems, a series of destructive issues may arise after installation and use over time.
Photovoltaic module adhesive sealing requires the use of high-quality, high-performance sealants with a warranty to reduce issues, increase reliability, and improve efficiency.
