Eden Full, Roseicollis Technologies

A low-cost and easy to build solar tracker with a built-in water filtration system.

Product description Brand name and product description

The SunSaluter is a solar panel rotator that couples energy collection from the sun with water purification. This system utilizes gravity to rotate the solar panels throughout the day, improving energy efficiency by 30% without complicated mechanics. Water from the WaterClock slowly drips through a filter, landing in a clean collection bottle, rotating the solar panel ever so slightly. It should be noted that the SunSaluter is a wooden rotator; the solar panels, battery, and other components need to be purchased separately.

The product was designed by Eden Full, SunSaluter found and chair of the board. Video on the performance of the tracker.
