The project is located in the south side of Haiyang City, Shandong Province, 30 km offshore and 30 meters deep. The 500 kW floating offshore PV consists of two ring-shaped floating units, each with an installed capacity of 250 kW, consisting of a ring-shaped wind and wave-resistant floating body, a high-strength film resistant to the marine environment, and a PV system. On the floating unit with a diameter of 53 meters and an area equivalent to 4 standard basketball courts, 770 PV modules are installed. The clean electricity generated from the modules is fed into the inverter and sent to the wind turbine platform of Peninsula South 3, which is operating at the same site, and will then be sent to the grid through the offshore booster station. The demonstration project verified the floating body, anchoring, wind and wave resistance of power generation modules and weather resistance of marine environment, and verified the technical feasibility of grid-connected scenery in the same field.
The project manager introduced the ring-shaped wind and wave resistant floating body of the offshore PV power plant is prefabricated by high-density polyethylene fittings, with a height of 0.6 meters to 0.8 meters, anchored to the seabed through four mooring points and 12 cables, with the wind turbine safety distance maintained at more than 60 meters; the middle of the floating body to create a new PV module platform, according to the sea conditions using customized PV power generation components, which can reduce the impact of waves on PV panels, while PV modules are connected with elastic film using prefabricated sliding rails and directly contact with seawater through the film, and the cooling of PV equipment by the water body can effectively improve the power generation efficiency by more than 10%.
