Flexible transparent condenser for solar panel in e.g. building roof, has exchanging unit maximizing and minimizing drop shadow of summer sun and winter sun under strong impact, with respect to normal of receiver and condenser, respectively

摘要

The condenser (1) has a reflective coating e.g. impression coating, and a heat exchanging unit (3) provided on a surface (2) turned towards solar radiation, where the condenser is made of shaped fabric and is in the form of a skew plate. The unit maximizes and minimizes drop shadow of summer sun and winter sun under strong impact, with respect to normal of a receiver and the condenser, respectively. The coating comprises nanometric titanium dioxide or catalyst for favoring transformation of volatile organic compound e.g. carbonmonoxide, into harmless elements e.g. carbondioxide.
