Rawlemon has created a spherical solar concentrating system that produces efficient solar energy in any place.

We are actually able to +70% of energy than conventional PV panels, thanks to our sphere and patent pending dual axis tracking system. We are also able to concentrate diffuse light. Our aim is to balance energy consumption , combing aesthetics, efficiency and autonomy. By combing spherical geometry and principals with our dual axis tracking system , Rawlemon can reach up to +70% yield surplus compared to a conventional PV panel, when both are placed in vertical setup. This allows for Rawlemon products to be integrated everywhere and anywhere. At the same time, we reduce the cell surface to 1%, which offers a revolutionary perspective on producing sustainable and low cost energy.

Our goal is twofold: to give us ample marketing opportunities for our alternative solar energy technology, and a sufficient lead time to launch a revolutionary architectural system for buildings which will be energy independent and generate surplus energy at the same time.

The  Microtrack is able to produce energy in facades and assure 99% of transparency . It could be installed as a building skin , producing energy during the day as a multimedia support during the night.

We believe in producing energy where people actually live: in our cities. And we will do this without sacrificing beauty , the transparency of a window, or a comfortable living environment. We want it to be democratic, and with your help, we will be able to engage a revolutionary in the renewable energy sector : a new way to produce energy and to reduce the impact of climate change on our planet.

On discovering the ball lens is the perfect sun tracker for solar applications because of its geometry, they realised it was a chance to reconsider the way we produce renewable energy. Having been through a long research and creative process, from early studies, concepts and sketches to 3D models, calculations and prototypes, loads of ball lens studies, through to measuring the performance and the energy transmission values. Through these tests they reached the conclusion that the perfect shape of the ball lens not only has excellent energy transmission but also the capability to concentrate diffuse light.

Finally, they arrived at the first certification of the façade module featuring multijunction cells (for space applications); realised in January 2013. This certification demonstrated the high potential output of our system. Multijunction cells can only function with concentrator systems. By using a high efficiency multijunction cell, we have reduced the cell surface down to 1% , compared to the same power output  as a conventional silicon cell  in optimal conditions. In combination with dual axis tracking, our system generates twice the yield as a conventional panel. In addition, our smaller cell area has a lower carbon footprint because its production requires fewer precious semiconductor or other building material.
