A ±60° Field-of-View,Highly Compact,3×3 Integrated Photo-diode Array Sensor for Dual-Axis Solar Tracking
Solar energy production via photovoltaic (PV) cells has witnessed over 500% growth in cumulative installed capacity between 2006-2010 1.With this significant investment, there is a financial need to maximize the system s power output, which can be achieved via a solar tracking system.The objective of this paper is to introduce a new, highly compact, integrated sensor consisting of 9 photo-diodes arranged in a 3 ×3 grid with 4 light windows in a 2 x2 grid.The design allows simultaneous dual-axis solar tracking to take place with a single solid state sensor.Field-of-Views of ±58° azimuth and ±52° elevation and sensor calibrated errors of ±1° and ±0.3° in the azimuth and elevation direction, respectively, were obtained.
