What is the HelioWatcher?

The HelioWatcher is solar power analytics system designed to automatically orient a solar panel for maximum efficiency, record data, and safely charge batteries. Using a GPS module, an accelerometer, and a magnetometer, the HelioWatcher allows the user to place the system anywhere in the world without any calibration. The HelioWatcher uses these sensors paired with a solar tracking algorithm to autonomously calculate the sun’s current location and orient the panel to the appropriate position. It also utilizes a quadrature of light-detecting diodes to correct for short-term light obstruction, such as clouds or shade. Data is logged to a computer to allow the user to visualize the efficiency gains and power consumption in real time or after the data collection has occured.

 

The HelioWatcher was designed by Jason Wright and I for our ECE4760 (Designing with Microcontrollers) final project at Cornell University. Jason is the same person whom I worked with to develop the Nerf Sentry Gun for our Matlab Robotics class freshman year.
