SP2 | Submerged PV Panels

This project has successfully gone through a long period of testing and it is based on three principles:

PV_sommersi 

  • Nearly all of the photovoltaic material, in particular silicon and CdTe, have a negative thermal drift, i.e. they lose efficiency when the temperature increases.
    Therefore they are less efficient when the sun is most intense.
  • Photovoltaic panels use predominantly visible radiation.
  • Water keeps the temperature of the panel constant thus avoiding the thermal drift, and at the same time the panel doesn’t lose efficiency as it absorbs mainly the infrared.

SP2 allows us to realize a gain in efficiency of approximately 20% during summer time.
