EPDM offers excellent resistance to weather and mechanical stress, making it the workhorse for most standard residential solar projects. Silicone, conversely, wins in high-heat environments or where chemical compatibility with roof coatings is a concern. Solar energy systems, particularly photovoltaic (PV) panels, rely on gaskets to prevent moisture. Most solar panel seam gaskets are made of EPDM, a synthetic rubber that resists sunlight, ozone, oxygen, weather, water, and a wide range of outdoor temperatures. Solar panel manufacturers can also use gasket materials that are co-extruded. Solar Inverters: UV-Resistant Gaskets for 20-Year Outdoor Exposure. Solar inverter gaskets face prolonged UV exposure, thermal cycling, and chemical degradation. Standard EPDM compounds degrade under UV radiation, leading to compression set failure and seal leakage over time. EPDM lacks UV. The structural integrity of a solar photovoltaic (PV) array is fundamental to its long-term performance and safety. A silent and persistent threat to these. Corigy Solar provides high-quality EPDM rubber gaskets specifically designed for solar panel installations, providing superior sealing and protection for photovoltaic mounting systems.
