Photovoltaic - Electric power direct from light

Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.

  Proudly announces Evergreensolar with only 25,4 g CO2 per kWh solar electric power at their photovoltaic modules. At the calculation, the CO2 at the production is distributed on 25 years.

  Current under development, more than 40% efficiency of the photovoltaic ceell at 500 times concentrated sunlight is the target. Below each lense, an only 7mm * 7mm cell.


Fashion color black: new photovoltaic with more achievement Fashion color black: new photovoltaic with more achievement
  With an increase in output of the crystalline silicon cells also there came a color change. Instead of up to now blue gleaming, present the new cells in deep black.

  This on both sides active photovoltaic offers new creation elements for the architecture. Maybe a garden fence or the balustrade for a patio.


Photovoltaic compare
  A 20 Watt crystalline silicon photovoltaic from 1998 vs 3 layer amorphous from Uni-Solar. Under dense clouds, the crystalline PV has no chance.
