2.3 Solar Tracking:
A solar tracker is a device which can orients various payloads toward the sun. The Payloads can be photovoltaic panels, reflectors, lenses or other optical devices.
2.3.1 Single axis horizontal tracking: In the single axis horizontal tracking the axis of rotation of the tracker is horizontal with respect to ground. It rotates the module 180 degree.
2.3.2 Single axis vertical tracking: In the single axis vertical tracking the axis of rotation of the tracker is vertical with respect to ground. It rotates the module 180 degree
2.3.3 Dual axis tracking: The Dual axis trackers have two degrees of rotation freedom that act as axes of rotation. These axes are normal to one another. One axis is fixed with respect to the ground can be considered a primary axis. The …show more content…
We will program the microcontroller by using C-language basic for Proton IDE compiler. Details of Proton IDE have been given in Chapter#06.
