DNV publishes guidelines for proper deployment of floating PV


From pv magazine International

Rebranded, Norway-based consultancy DNV has published a guide to help renewable energy developers in the construction of floating solar power plants.

The Recommended Practice guide, on top of describing the most common requirements for building a floating PV array, provides a series of technical guidelines for electrical safety, anchoring and mooring issues, operation and maintenance, and specific plant design that can withstand site-specific environmental conditions. “It aims to be valid and applicable in all major markets and geographic regions, for all defined applications within scope, from component level to system level, covering the entire life cycle,” its authors specified.

“It will take the industry around five years to reach full standardization,” said DNV consultant Michele Tagliapietra, adding that standards set by the IEC, ISO and DVN will be defined within two to four years, depending on component.

Launching the first global recommended practice document for floating solar, the company underlined that the technology requires significant attention on some parts of the system in the medium term. At the same time, a focus on durability and degradation will be needed in the long term.

“At the moment, in the medium term, the main cause of failure is [the] anchoring and mooring part of the system. This is not a surprise because these are new challenges for PV developers,” explained Tagliapietra.
