A floating solar power system supplier named Mibet has recently unveiled a new product designed for deep-sea environments. The MRac Floating PV Mounting System G4M, made from high-density polyethylene and zinc-aluminum-magnesium coated steel, is engineered to handle challenging conditions like fluctuating water levels and strong winds.

The system has already been tested in a 326 kW floating photovoltaic array in collaboration with Indonesia's state-owned electricity company, PLN. This project is located on a reservoir in South Kalimantan, with water depths up to 60 meters and significant water level changes. To address these challenges, the system uses point-to-point mooring measurements and a gravity anchor block reinforcement strategy.

The G4M system supports both framed and frameless PV panels installed at a tilt of 5 degrees to 15 degrees. It can withstand wind loads up to 45 meters per second and snow loads of 1 kN/m2. The module floater has a bearing weight of 90 kg/m2, while walkaway floaters support 150 kg/m2. Floaters are available in short, long, or portrait configurations.

Mibet highlighted that the G4M system consists of four types of floaters, which can be flexibly combined. Its modular design allows for a three-row panel layout, reducing the amount of floater material required while increasing installed capacity within the same area. The main floater module features a Y-shaped design, and the contact area of the floaters' protruding connection points has been expanded to ensure even force distribution at the joints.
