I have not tried never, but I think it should not be very efficient. I'm curious, so this weekend I'll try to do it and see the results. I live in an area with a high solar irradiance, higher than 5.5 kwh / m2, so if it does not work here, it will hardly work anywhere else.
When I have results I will publish them
It would be greatly appreciated to hear from someone whos tested it first hand thank you for the feedback!
