    LM7805 does waste energy since it is a linear regulator: It is a self-regulating resistor.

    It would be much more efficient if a buck-boost or inverting DC/-DC-Converter would be used. a bit more costly, but could also charge if dim light and panel gives <5V and does not waste this much energy (Normal eff is 80-96% normally).

    something like http://www.aliexpress.com/item/Auto-DC-Boost-Buck-... as an example...
