Europe´s first solar concrete wall was inaugurated recently at RECKLI's headquarters in Herne, Germany. Accordiing to a press release:

This solar active concrete wall is the result of a joint development project of RECKLI and Heliatek. With an installed power of 1kWp, the south-west oriented wall will supply around 500 kWh of electricity per year. The energy produced will be used directly by Reckli. The annual energy output is expected to be about 25% above the yield of silicon technology. Heliatek has already shown that its solar film, HeliaFilm, delivers more energy under overcast sky conditions and at high temperatures compared to traditional solar cells. This advantage is based on the unique properties of its organic semiconductor. In addition, HeliaFilm allows a wide range of colors and flexible layouts – both features sought after by architects and planners.
