The company Solarzaun has implemented its first project in Elsau in the canton of Zurich. The fence is 25 metres long. The eleven bifacial modules have a rated output of 4.4 kilowatts and deliver 3,500 kilowatt hours of electricity every year. That is enough to cover part of the electricity needs of the house in front of the solar fence.
Solar fence supplies 3.5 megawatt hours per year
It is a small project. But it is a start for the company Solarzaun, which is currently looking for areas in the Winterthur region for further installations for test purposes. It should be an area in an industrial or commercial area. It must be large enough to erect a ten to 20 metre long solar fence. The fence should not be too close to the property line so that tests can be carried out on it. Interested parties can contact the company Solarzaun.
Originally developed for agriculture
The solution consists of mounting posts driven into the ground between which bifacial modules are installed. The basic principle of the installation goes back to a development by Next2Sun. The company originally developed the possibility of vertical installation of solar modules for photovoltaic systems on agricultural land.
Concept converted to a solar fence
Because the modules necessarily have to be far apart so as not to shade each other, continued cultivation by the farmer is still possible. The Austrian company Elektrotechnik Leitinger has developed this approach into a fence. The company Solarzaun has in turn adopted this concept to market it in Switzerland and realise projects there. The fences can be built at different heights and uneven terrain or installation on slopes are no problem. (su/mfo)
