windscreen reflective sunshade

[Tookey]

Before I give it any proper consideration;

If parked for a few days do you think a reflective windscreen sunshade positioned around a pv panel would aid morning/evening sun harvesting to a level that it is worth the faff?

sounds plausible might work like those Solar Ovens you seen some guys in the US Deserts using? (although Solar is best in bright COOL conditions, and that could make it less efficient if the result is greater heat?
(can you tell I have no real idea be interesting to try though )
