I like to size my loads to about 6 hours of the rated output of the panel. So for one panel, you can have 600 watt hours per day. For perspective, I have a router that draws 12v2a, or 24 watt hours. That would need 576 watt hours per day, so this panel would be just about perfect.

In summer it's probably more like 8 or 10 hours but I like to size for winter so that I can be sure I'll be powered year round.

You'll also need a fairly sizeable battery; the smallest you could safely get away with is 12v30ah since the battery will power the device overnight and the panel would charge the battery and run the device during the day. You'll also need a charge controller.

This is just one example.

I got some marine batteries from costco, and a cheap controller from amazon. should be no diff if you have under 200 W for a 20$ contorller or 200$ controller

Mono is more efficient in converting sunlight into electrical energy. Mono is also more expensive but for my use it's worth the extra cost.
