  • 18. LIMITATION OF SOLAR ENERGY• The initial cost is high• Solar panels require quite a large area for installation to achieve a good level of efficiency• The efficiency of the system also relies on the location of the sun• The production of solar energy is influenced by the presence of clouds or pollution in the air• No solar energy will be produced during nighttime• As far as solar powered vehicles go - their slower speed 18 SOLAR IMPULSE HB SIA
  • 19. SOLAR CELL• A Solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect.• The photoelectric effect: emission, or ejection, of electrons from the surface of a metal or non metal in response to incident electromagnetic radiation. 19 SOLAR IMPULSE HB SIA

  • 22. LOSSES IN PV CELL• Electromagnetic radiation is not monochromatic• band gap energy of a material• power is voltage times current (P = V x I).• The optimal band gap, balancing these two effects, is around 1.4 eV for a cell made from a single material.• opaque contacts on upper surface. 22 SOLAR IMPULSE HB SI
