DNV to create floating solar standards
DNV, the independent energy expert and insurance provider, estimates that the potential global capacity for floating solar photovoltaic (FPV) deployment is currently around 4 TW and installed capacity will reach 10 GW worldwide. by 2025.
Although the development of large-scale ground-based photovoltaic systems may be more difficult due to difficult terrain or land scarcity, many bodies of water remain widely available for power generation, making the analysis attractive FPV business case. After a slow start, the FPV market has grown to 2 GW of global installed capacity in 2020. DNV expects a total of 7 GW to 11 GW to be installed by 2025 with a significant increase from 2023.
However, standards for FPV are still largely lacking, which can lead to project delays and obstacles in granting permits and approvals, which can be a problem for the large-scale renewable energy industry. FPV players rely at best on inconsistent and diverse procedures and adjacent codes adopted by other sectors, which can hamper the industry’s ability to grow rapidly.
To provide comprehensive guidance to FPV operators, DNV led a JIP involving 24 industry leaders to develop the world’s first Recommended Practice (RP) on the design, development and operation of FPV systems. DNV-RP-0584 was successfully introduced in 2021 as the first step on the way to FPV standards and certification.
Following this breakthrough, DNV has been working to work with industry players to move from recommended practices to FPV-specific reference standards. This has enabled them and their stakeholders to manage risk and complexity with confidence, supporting the transition to renewable and low-emission energy sources.
DNV has taken the lead in two new JIPs to achieve this. The first is to share and improve best practices for designing FPV-specific anchoring and mooring structures. Based on a selection of floating solar concepts, the project – which brings together stakeholders from all areas of the FPV field – will address a variety of challenges expected when deploying installations on larger, shallow-draft islands. The second JIP proposes to leverage DNV’s expertise and network to create an adequate unified standard for the design, testing and qualification of FPV-specific floats that will introduce clearer, faster and more efficient performance-based procedures. less expensive, configuration independent and failure mode specific. .
“Using industry standards will ultimately lead to higher quality, lower failure rates, and more adequate access to data-driven digital solutions and assurance services such as verification and certification. This can only be achieved through joint efforts and continued knowledge sharing,” said Juan Carlos Arévalo, Executive Vice President of GPM&S, a DNV company. “It will not lead to the convergence of solar technology floating photovoltaic towards a dominant concept, but will instead establish a common approach to analysis and simulation that allows players to constantly improve each other’s best practices and put in place testing and quality assurance procedures industry-wide. .”
“FPV structures present unique challenges for the solar industry due to specific hydrodynamic loads, corrosion risks and specific components, such as floats, anchors and mooring lines,” says Dana Olson, project manager. global segment for solar energy, Energy Systems at DNV. Several large customers in the solar community have asked us to develop new bespoke standards to guide them in the development of resilient FPV projects. In particular, our contribution to determining the design environmental load will provide crucial guidance to the entire field, and we look forward to engaging directly with industry customers at this critical stage of FPV project development.” , Olson said.
