Geez stuff gets here quick from the Philippines. Boat people must be paddling quicker.
So, 9 cells at supposedly 160mA each.
Being conservative let's say they do around 100mA each,.
That's still about 1 amp in full sun which should be just enough for the camera. You'd be stuffed on cloudy days though.
The shinny top clear coat on those cells tend to go dull after being exposed
to sunlight. That reduces output. Cheap garden lights are similar and die all the time for that
reason. Not sure what to use, but a wet silicon spray or oil coating might help keep them fresh.
Maybe a coat of Poison Ivy's vaseline he uses to lube his pram wheels?
This your first solar project Number 7?
My first project was a few of those cells with a control charger
strapped on a flat board that sat on an engine-less mower
with a car battery - Would have taken 2 years to charge the battery once.
I had a video of it but it in hindsight it was so embarrassing that
I deleted it from Youtube a while ago.
