To maximize your solar PV system's energy output in Vaduz, Liechtenstein (Lat/Long 47.1322, 9.5115) throughout the year, you should tilt your panels at an angle of 40° South for fixed panel installations.
[pdf] MIT engineers have developed ultralight fabric solar cells that can quickly and easily turn any surface into a power source. These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface.
[pdf] Building-integrated photovoltaics (BIPV) are evolving beyond simple solar panels, with transparent solar cells and solar skin technologies that can be seamlessly incorporated into windows, facades, and other architectural elements.
