The Sun is the greatest sustainable energy source available to us on earth. However, there is the problem of low efficiency since the vast majority of PhotoVoltaic panels worldwide have a performance of just 15% or lower; and if the panels aren’t tracking the movement of the sun in the sky, there are further losses of 40% during the year. By combining spherical geometry principals with dual axis tracking system, Rawlemon solar devices can reach up to 70% yield surplus compared to a conventional PV panel, when both are placed in vertical set-up. The reduced cell surface to 1% offers a revolutionary perspective on producing sustainable and low cost energy. Rawlemon products can be integrated anywhere and everywhere. There is also smaller desktop version of the product for daily use to charge phones and other electronics.
