whole idea is i wanna do with cheaper solution , I wanna use only rtc, linear actuator and arduino board for the project.If i am using above component is it possible to it??if yes how can i do it??how can calculate sun elevation angle??i don't have any sensor to locate and control the position.
How accurately are we trying to track the sun's position? Some of the solutions being discussed seem to be aimed at very high accuracy indeed - which might be justified if we're trying to aim a telescope but would be ridiculously over the top if we're just trying to point a solar panel in the right general direction.
