SunPoint is a recently formed company seeking to make a rooftop solar tracking system designed to boost the output of solar photovoltaic panels. Engineers are working on a thermomechanical tracking system which is powered by the heat from the sun, using differences in metal temperatures in the tracker (seen under the panel). The company plans to design the system for commercial rooftop solar systems, according to a representative.
