It illuminates its target and measures the reflecting energy back to the camera. If you are entitled to claim back money, then why are you not doing it?. Figure 1: Typical cross section of a passive solar building 1. An “active” solar panel may include a tracking system to maximize the solar exposure while a “passive” one would be set at some fixed position. Difference between these two is quite small, however, leaves great impact on their functionality. The core difference between solar PV and solar thermal can be found in their working principles. I like the passive ones because they are generally simpler and less prone to mechanical failure.
