I have been testing it outside from last night. Battery went down to 45% during the night.

This morning really cloudy and to my amazment the % was going up 1% every 15min on the sensor read cycle.

The panel im using a 2.5W epoxy type cheap ebay panel. Its scrached a lot and in really bad shape.

I think it cost me like 3-4$ on ebay

So this is a WIN. Il leave it outside a week or two and see what happens.

Hopefully it wont lock up since i have not implemented the WDT timer to clear lock up's.
