Sunflower Solar Positioning System.

The Sunflower Solar Panel Positioning System is a microcontroller based solar tracking system designed and built by Robertson Robots. As well as being a cost effective method of increasing solar panel production, the system can also be easily modified and reprogrammed to perform a large variety of other tasks including sensing and control applications.

The Sunflower tracking control system is available in two models, one for very large panels or multi-panel arrays and the other model is for smaller single-panel arrays.
