Solar Panel requirements were for minimal output to
fully charge various combinations
of selected batteries; and for portability, the ability to be rolled up, or folded
into as small a volume as possible.
These units have been extensively tested, and in
combination with tested
battery configurations have been able to run a Raspberry Pi
Zero-based weather station
continuously for 5 days straight:
Rollable Panel:
This panel is rated for 90 watts.
Foldable Panel:
This panel is rated for 120 Watts.
Folding Panel:
This panel is rated for 120 Watts.
A data logger was constructed to obtain
useable data for solar panel voltages
over a time
period of twenty four hours:
This data applies to a terrestrial location at the following coordinates:
27.6351° S, 152.7747° E
for comparison, similar data was obtained during the Devon Island expedition,
and applies to terrestrial location:
75.1982° N, 81.8512° W
data to follow
In order to obtain usable power across all daylight hours, a datalogger
was attached to the foldable panel, and voltage output was logged over
a number of days.
