looks like there are (led?) lights under the pictured double-sided gas station solar panel canopy. letting some of the light through would be more efficient that the conversion to electricity and then back to light. and yes, you'd still need lighting at night, but a semi-transparent roof combined with the wider area lights already in use at gas stations would still likely be more efficient. (of course this doesn't consider the value of the shade on hot days)
