Feel dirty by asking... Generic MPPT solar CCs?

I think it's location and weather specific. Where we camp SE was best to take advantage of the morning sun before the clouds rolled in. last trip I laid it flat on some logs with a slight eastern tilt and we never had to worry about the battery.

As far a s cheap panels go, there is a person here selling for 69 cents a watt by the pallet. No tax and local to me if I didn't already have my panels.
