Use FM Approved roof-mounted solar PV assemblies that are tested and rated for exterior fire spread and have a suitable wind and hail rating. Because the roof and PV assembly interact with respect to exterior fire
The new FM Approvals certification program for PV modules can help meet these needs by providing an efficient one-stop certification resource. FM Approvals is the leading third-party testing laboratory for the certification of commercial roofing products in the world.
Aside from offering a solar solution for places where available land is scarce, research from Bangor University and the University of Lancaster discovered that floating solar installations could reduce water loss from bodies of water during periods of extreme heat, and could also reduce the prevalence of damaging algal blooms in lakes.
This standard does not qualify flexible photovoltaic modules. Flexible photovoltaic systems are evaluated per FM Approvals Standard 4476. Purpose. This standard states the testing and certification requirements for rigid photovoltaic modules that are installed with a certified roof assembly.
The AFREC mandate is implemented under four main programme areas, developed and approved by the Specialised Technical Committee (STC) on Transport, Transcontinental and Inter-regional Infrastructure, Energy and Tourism (STC-TTIIET) held in Cairo, Egypt in April 2019.
"We are excited to have the first FM Approved PV systems for standing seam metal roofs," says Cy Ketchum, FM Approvals'' Materials Engineer. He goes on to describe how "the demand for more approved products, including systems with expanded wind uplift ratings, continues to gain momentum".
This standard applies to all rigid photovoltaic module systems intended to be 1) mechanically fastened through or attached to an FM Approved single-ply, polymer-modified bitumen sheet, built-up roof, liquid applied roof cover or steep slope roof (mechanically attached only), 2) mechanically fastened to a metal panel roof cover assembly using

FM Approvals and TÜV Rheinland have come together to form new approval standards for flexible and rigid PV modules.
However, the UK has seen few floating solar projects take off, despite the potential they hold. There are precious few floatovoltaic installations operating in the UK at present.
Using just 2.3% of the total area of Europe’s hydropower reservoirs for floating solar installations could produce 42.3TWh of power each year. Given that the UK has around 570 reservoirs (although not all of these produce hydropower), floating solar installations could provide a significant boost to UK energy security.
