Abstract:

The unique photovoltaic power plant installed in Prague on the roof of the new buildings of National Theatre in Prague has been investigated. As the new buildings are very close to the old historical building of National Theatre designed in late 19th century, the PV power plant has to be totally invisible from the streets of Prague to not disturb historical panorama of the city. Flexible a-Si photovoltaic foils in the nearly horizontal position have been used because the placing is in the urban conservation area in the historical city centre. The operation started in the autumn 2009. The photovoltaic power plant is described in this paper and results of its operation are presented. The energy production data indicate that the degradation of the nearly horizontally installed a-Si panels is below 5% within 5 years period.
