Sun Tracker for Solar Panel Research ASTX-500
ASTX-500 is a 2 axis (Azimuth&Zenith = horizontal and vertical) sun tracker. While mounting the solar panels, ASTX-500 always follows the direction of the sun accuratelly, by the sun position sensor and built in CPU. Based on those features, solar panels are always facing to the sun (that optimize the power generating efficiency). This instrument is suitable for the evaluation of the solar panels. Both sample panels and standard panel can be mounted on this sun tracker for the comparative evaluation. Together with the solar panel, pyranometer and pyrheliometer also could be fitted for more detailed research. Data processing sysmtem could be supplied as option.
