DNV has released two new guidelines related to floating solar systems. The independent energy expert says the new documents are aimed at improving the safety, reliability and long-term performance of such systems amid the rapid global growth and expansion of renewables.
DNV-ST-C108 covers the structural design of floats for floating PV systems. It defines technical requirements for the structural design and qualification of floating PV float structures and features a design approach that considers the potential consequences of float failure.
The standard includes requirements covering safety classification, design basis, material qualification, structural design, testing and corrosion protection, with emphasis on non‑metallic materials and degradation due to solar irradiation.
