The EJOT Solar Fastening is designed for installing photovoltaic and solar thermal systems on commercial, industrial, and agricultural buildings. It features a thread-form that securely fastens into metal or wood structures, a depth stop for accurate installation, and a sealing system to prevent leaks. Variants are available for different roofing materials and substrates. The fasteners install quickly and securely while minimizing risk of damage or leaks.
