Energy Generation: Floating Solar

Solar radiation is distributed over the entire planet. 50 percent of the population lives near the coast taxing land and fresh water resources. Combining these facts to tap solar as a truly sustainable resource, demands a fresh solution. DNV KEMA's SUNdy concept for a large scale floating offshore solar field concept, brings this vision a step closer to reality.

The core of SUNdy is a 2 MW hexagonal array which floats on the sea surface. The scalable design can be deployed independently or linked together with others, providing electricity that can grow with societal needs. The SUNdy concept is made possible using thin-film 560 W solar panels. Thin-film solar panels are cheaper and gaining market share, with efficiencies approaching those of crystalline silicone. These thin-film panels are flexible and lighter than the traditional rigid glass-based modules, allowing them to undulate with the ocean’s surface.


Creating solar islands

An array of SUNdy floating modules would be manufactured as a pre-wired unit, significantly reducing the number of electrical connections while also minimising the need for offshore assembly. A collection of these arrays, totaling 4,200 solar panels, forms an expansive solar island the size of a large football stadium, capable of generating 2 MW of power. Multiple islands connected together constitute a solar field of 50 MW or more, producing enough electricity for 30,000 people. Islands would ideally be located in benign waters with depths ranging from 20–100 m and approximately five miles from shore away from shipping lanes.

The main beneftis include:
  • The oceans provide abundant space close to energy demand
  • Absence of moving mechanical parts gives high reliability with low operating costs
  • Buoyancy supports the panels, allowing for a simple structure
  • Low visual profile in the ocean, avoiding visual disturbance
  • Air and seawater cooling promote higher efficiencies
  • Abundant water for cleaning
  • The modular scaleable system is cost effective to manufacture
  • Environmentally friendly

  1. The World Goes Solar. Japan's FiT in July is among the highest in the world. Japan's FiT is shaking the solar market. Now, Asia has the same options. New solutions will be showed in Japan. This is it!
    As you know, earthquake in Japan is happening frequently. Floating solar panels installation is one of the best solutions for power crisis in Japan. So you have to reduce vibration to install Floating solar panels. Because, it makes many kinds of problems! Vibrations caused by wind, waves and external forces. New Floating Body Stabilizer for Floating solar panels installation has been created in South Korea. The Floating Body Stabilizers generate drag force immediately when Floating solar panels are being rolled and pitched on the water. Recently, these Floating Body Stabilizers have been used to reduce vibration of Floating Solar Panels in South Korea. You can watch New Floating Body Stabilizer videos on YouTube. http://youtu.be/O2oys_YHhCc, http://www.youtube.com/watch?v=nA_xFp5ktbU&feature=youtu.be.
