Acquired a 62 watt solar panel of the CIGS variety.
Shoveled the driveway and then splayed the panel on my car's trunk atop two pillows.
Wanted to test the panel's output under the worst possible conditions:
—four days before the northern hemisphere's winter solstice
—100% overcast/cloudy skies
—no direct sunlight (just a homogeneous, even light)
Date:
December 17th, 2016
Time:
1:08 P.M.
Latitude:
41° North
Ambient Temperature:
28.8°F = -1.77°C
No Load Voltage:
20.5V
No Load Current:
170mA
Computed No Load Power Output:
20.5V * 170mA = 3.485 watts
I will run this test again on a sunny winter day, and, if I can remember, on a cloudy/sunny day in March (around the vernal equinox) and on a cloudy/sunny day in June (around the summer solstice).
