The Spherical Solar Energy Generator Created by the German Architect Aims to Improve the Autonomy of Solar Panels Allowing Consumers to Depend Less on Utility Companies
The German architect and founder of Rawlemon, André Broessel, developed a project that consists of a symmetric and transparent sphere, which is capable of increasing the efficiency of photovoltaic panels by up to 35%. Designed similarly to the way a magnifying glass works, the new spherical solar energy generator has an effect that helps to intensify the sunlight that passes through it.

In addition to capturing sunlight more broadly, the sphere is also capable of concentrating light that is diffused from the sun or even from the moon. Even on cloudy days, the device can produce about four times more energy compared to a conventional photovoltaic solar energy system.
The dual-axis in the generator allows for the incorporation of a natural and rotational optical tracking device, which is ideal for use on naturally inclined surfaces.

This way, sunlight is captured at one pole and then reflected and amplified at another pole, concentrating solar rays in a unique and designated area. The small solar panels allow for the capture of the ray.
Generator Was Developed to Be an Independent Energy Charging Station
An IndieGoGo campaign was essential for the project to become possible. Throughout the campaign, approximately R$ 1,266,215.00 was raised from 1,228 different contributors.
The sphere was entirely developed to be an independent energy charging station, specifically to assist photovoltaic solar panels in the light capture process.
Its geometric structure was strategically designed for the model, aiming to improve the energy efficiency of energy collectors. According to the Rawlemon architect, when the silicon cell area is reduced to 25% with equivalent power and using the ultra-transmission point-focus concentrator, the sphere can operate at various efficiency levels, reaching almost 57% in hybrid mode.
Architect Believed Technology Could Help Replace Semiconductor Chips
In 2013, architect Broessel was a finalist for the World Technology Network Award with the sphere project. Recently, he developed a new version of the globe that concentrates diffuse light.
Although the technology is already known, the architect’s original idea was to aid in the replacement of chips – even without knowing that years later the world would face a supply crisis for these chips – as a means to supplement the use of semiconductors or high-cost technological devices. Regarding the design of the sphere, its circular shape allows it to function on top of any building or even in a conventional house.
Another version of this same device is being developed to attach the solar sphere to the windows of buildings in commercial centers. With its perfect geometric shape, light is concentrated at a specific point, making it much more sustainable, because the source from the sun is much more efficient and renewable.
