High productivity non-tracking solar collectors for process heat applications

Our solar collector is unique in the world and patented. The solar collector has a large acceptance angle of 127° which achieves day-long collection efficiency without solar tracking system and can receive diffuse solar irradiation, making it very attractive for any climate, especially in tropical zones. The solar collector uses a wet metal-to-water contact, which increases the heat transfer capability. The efficiency of our solar collector is higher than a commercial evacuated tube solar collector which generally uses a dry metal-to-metal contact. Our collector needs 50% fewer tubes to capture almost the same energy as an evacuated tube solar collector of the same area. This leads to a reduction of the cost of the system. Therefore this new solar collector is not only suitable for small residential houses but also for process heat applications as in industrial uses.
