I have a generator and I have two 40 watt solar
panels. I have no air.
I ask myself the same questions every time I go camping. If I take the generator, I need to pack a gas can and if I run it, I'll annoy neighbours.
If I take the portable panels, I need sunlight and it takes longer to charge the battery than using the generator. I would also worry about theft when not at camp ( although I've seen lots of people just leave them out and go fishing ).
The panels and the generator weigh about the same.
In the event of a power failure at home, I can pull out the generator and run emergency power for a small heater or to run fridge/freezer ( I'd actually just move into the trailer and run everything on propane
Over to you.
