100W Sunpower Foldable Solar Panel（18v Output ） Portable Solar Charger For outdoors ,hunting,hiking ,camping, Fishing, RV,Boat
Just to give some idea of the performance,
80 watt panels, on inside of window facing south
Minimum Dull Cloudy – 14 V X 0.0050 A =- 0.07 watts
Bright Cloudy – 17 V ,X 0.150 A = 2.55 watts
Some sun – 26.6 V X 1.12 A = 29.792 watts
Not had summer and long proper sunny days with em yet..
You gotta expect less out of your panels indoors, on a grey day the minimum charge youre going to get out of them is 0.07 watts ish, on a bright but cloudy day expect 2 watts ish and nearly 30 watt on a day with mild sunshine
