Solartek company of the TechnoSpark group from Troitsk (part of the investment network of The Fund for Infrastructure and Educational Programs RUSNANO) installed the first commercial flexible solar modules on the seam roofing of three houses in the Central District of St. Petersburg. Solar roofs with new generation modules harmoniously fit into the existing urban landscape.
The advantages of flexible solar modules are low weight and flexibility. They are installed without the use of heavy supporting structures. With strong roof heating, in the sunniest hours, the efficiency of most silicon panels falls down a lot, while thin-film panels do not lose performance even in bright sunlight. Solartek’s modules look like a thin extra roofing layer, in contrast to the traditional solar modules.
The high sensitivity to the scattered light of thin-film panels allows a decent energy efficiency even in restrained urban conditions. It also helps to reduce the general households energy supply and compensate part of the energy costs on the anti-freezing system.
“The potential of flexible solar modules becomes visible when installed on a ‘complex’ roof – our panels take the form of roofing sheets and protrude just a couple of millimeters above the roof surface. This way, the familiar appearance of the buildings and their aesthetics, conceived by the architects, are preserved. The use of mechanical anchorages allows removing flexible modules in case of need for spot repairs or planned replacement of the roofing sheet.”
Dmitry Yakovlev, technical director of Solartek.
Thin-film flexible solar cells integrated into existing and buildings under construction (BIPV or Building Integrated Photovoltaics) are one of the actively growing market segments in solar energy. In addition, thin-film modules are a key element in the implementation of the concept of a zero-emission house, since they increase significantly the area of a building, that can generate electricity, due to the use of not only roofs, but also facades, awnings, and even windows in the long term period.
