OUR PRODUCTS

An Ocean Sun system consists of one or multiple floaters anchored side-by-side to build larger power plants. The anchoring system is designed to take local water depth, wave, current, and wind conditions into consideration. The floaters are towed into place.

  • DNVGL Statement of Conformity[3]

Inverters

  • Smart string inverters, fan-less, fuse-less, IP66, designed for double glass modules without grounding
  • Leakage current and residual current management
  • Monitoring system

Buoyancy ring

  • Virgin HDPE100 material
  • Welding according to ISO 21307 or equivalent local code for pressure pipe design welding

Transformer

  • 3MWp or 6MWp medium voltage step-up transformers
  • Mounted on-shore or on a floating barge, depending on location and client preferences

Direct cooling from water results in up to 10% higher energy yield[1] compared to both ground-mounted and pontoon-based floating PV installations[2]. The map shows the globe highlighting the ±45° area in which Ocean Sun’s technology will maximise the efficiency gain from thermal dissipation.

System Warranty: Succesfully completed special PID certification of modules by TÜV Rheinland.
