How Does a Solar Concentrator Solar Dish Work? | Solartron

The 9 meter hybrid parabolic solar concentrator (solar dish) continuously tracks the sun throughout the day using a dual axis tracker enabling the system to harvest maximum solar energy from early sunrise to late sunset. Most solar concentrator tracking technologies use an actuator for vertical tracking. The 9 meter solar concentrator uses a slew drive instead of an actuator for rocksolid ...
