Well this is for a direct solar illumination project which requires tracking of sun. So if we consider that also .. which of the two would be better ??
In terms of tracking accuracy required and feasibility to track ...
which is better for concentrating sunlight ??
I m doing a project on solar illumination . I wanted to know which configuration of parabolic reflector/ collector is better in terms of efficiency - central axis (cassegrain) or off axis ??
