What I think you are asking is if you can tap into a wiring system for the vent fan to back feed a charge from the Go Power Eco Solar Charging System - 10 Watt Solar Panel, # 34273836. While this is not the way this product is designed to operate, and I do not suggest doing this, it may be successful in sending a charge to the battery. Like water, electricity follows the path of least resistance so this may do so if there is not a protection diode preventing reverse current flow. In addition what amount of added resistance are you introducing by going this route.
