South Africa-based solar project developer Phelan Energy Group has unveiled a new floating structure for solar modules that is based on a proprietary thermoplastic polymer frame technology and which, the manufacturer claims, is able to maintain the solar panels just centimeters above the water surface.
The FloatSun structure consists of a main float measuring 1,924×1,251x273x3mm and weighing15 kg, and a walkway float with a size of 1,910x400x200x3mm and a weight of 7kg. The two structures have a design buoyancy of 215 and 130kg, respectively, and both are produced through blow molding, which is a common manufacturing process for molding and joining together hollow plastic parts.
The first structure has the function of hosting the solar panel and provides a tilt angle of three degrees. The second ensures connection with other floats and is used for maintenance and to run the cables.

The float can host all modules with lengths ranging from 1,761 to 1,722mm, widths of 1,134 to 1,098mm, and a height of between 30 and 35mm. The cable length must be 450mm and the module should have a 120-cell design and have a output of over 400 W. It should also feature an IP68 enclosure rating and an MC4-compatible connector. A module's maximum weight must not exceed 30kg and its ideal output guarantee should be 30 years.

“Its sleek aerodynamic lines are designed with a cooling cavity and air vortex to maximize the water-cooling effect on the solar cells and increase power yields,” the manufacturer stated. “In addition, a unique, solar-powered, automatic ThermoKlean system constantly cleans the graphene-coated, high transmission glass and lowers panel temperature.”

Phelan Energy Group is developing the floats at its facility in Dubai, in the United Arab Emirates. It plans to produce 1 million units in the first year and a total of 5 million units within three years.

The wording “MC4-compatible connector” must be definitely banned from any professional readings, documentation, manual, datasheet, …etc , as per UL and IEC standards codes, brands intermating is both dangerous and strictly forbidden.
Hello Vince, thanks for your comment. I agree the wording should not be used anymore. I picked it from the product sheet, but you are right and this should be avoided in the future.
