I am building a solar collector out of drink cans, and have a 12v 1.6A fan that I would like to run for ventilation. When I hook it up to a car battery, it runs fine. When I hook it up to a 12v 1.5 watt battery charger, it does nothing.
What size (watt?) solar panel do I need to run the fan? Should I get a different fan that requires less power? I see these on you tube all the time and they all seem to run on really small solar cells? Help!
