Small solar panel for roof vent??????
Has anyone installed a small solar panel for a roof vent? My roof vent fan draws 1.2 amps, and I have two roof vents. Getting them off house batteries would save nearly 3 amps. I'm estimating I'd need...

Yes I have done it for my fiver to suck the hot air out of it while its in the storage lot. Yes it only works when the sun is out but I don't care because at night it cools off.
For one fan I bought the Hengs RV Vortex fan that fits into a standard vent and is powered by a 15W panel mounted on top of my AC cover with a quick disconnect power plug. The fan is wired directly to the panel and I have this fan in our kitchen/living room (highest point). The fan already comes with an on off switch built in.
In our bedroom I would need to take a pic of what I have done but in short, its a 10" fan that snaps onto the vent with another quick disconnect for power that is wired directly to a 15 or 20 watt flexible panel and I reversed the wiring on both fans so it is blowing the hot air out the vents.
I have maxair vent covers on as well. When we get to the CG I can press the on/off on the Hengs fan and close the vent, on the bedroom fan I simply snap off the fan, unplug the quick disconnect and close the vent for the AC.
I have been doing this for years because it can get pretty hot inside while sitting at the lot
