1. Solar photovoltaic panels are installed outdoors and are mostly exposed to natural environments such as wind, sunlight, and rain. As a result, the sealing materials on the surface and key parts of the photovoltaic panels are prone to damage and aging. Using silicone sealant to bond the interface between the photovoltaic panel and the frame can effectively prevent water vapor from seeping in, avoid short - circuits in the battery panels, and thus ensure the normal power generation of photovoltaic modules.
2. Silicone sealant has strong cohesion and adhesion, which can make the shell and connection parts of photovoltaic panels more stable. After curing, it forms a flexible adhesive layer, which helps to buffer the shaking and wear of the panels, enhances the stability and durability of photovoltaic panels, and extends the service life of photovoltaic modules.

As a key material, silicone sealant plays an irreplaceable role in the manufacturing and application of solar photovoltaic panels. With the rapid development of the solar photovoltaic industry, the market demand for silicone sealant will continue to grow, providing strong support for the high - quality development of the photovoltaic industry.
