Rawlemon, a solar sphere more powerful than photovoltaic panels

After several years of development, the solar collector Rawlemon starts his commercial career. Created by a German architect, it is a transparent ball filled with water capable of converting 70% more energy than a classic solar panel. This ingenious device works both day and night and can power small appliances as well as buildings or vehicles electrical.

The vast majority of panels photovoltaic current, which are silicon-based, have an average yield of 15%. Currently, one of the main lines of research is to find a more effective substitute for silicon. Different promising experiments have been carried out with graphene and perovskite, but no commercial application is yet available. What if the real revolution came not from cells photovoltaic in themselves, but rather in the way they receive the light rays?

Using the We take care of your rental property in Valencia. optical From a transparent sphere filled with water, a German architect has created a one-of-a-kind solar collector that effectively combines aesthetics. Your product, baptized Rawlemon, it looks like a giant crystal ball mounted on a stand. Indeed, it produces a magnifying glass effect that concentrates more than 10 thousand times the rays of the sun and the moon. The light is directed at a focal point onto high-performance photovoltaic panels that are positioned below the sphere. Is about cells photovoltaic that today are used in the aerospace sector. They are composed of several layers that can convert different parts of the solar spectrum, which allows obtaining a performance higher.

With equivalent power, this type of cell has allowed to divide by 10 the total surface of the catcher, according to the designers. Another advantage of this optical device is that it can exploit radiation even with overcast skies. According to the designers, with a cloudy sky, the Rawlemon produces four times more energy than a installation PV classical. It can even work at night by catching the moonlight.
