Re: Request comments on simple solar charger

Ah! Now I understand where you're coming from - but I guess you missed
the part where I said:

So the device does more than just run that 1A motor and do the comms
session.

This is part of why I was asking the question in here - the cells are
speced under ideal solar conditions, so I don't know how far to derate
them for real life. Considering the cost of the device, adding another
$300 to $600 in solar cells is money well spent if it significantly
improves the chance that the device will last for its intended
lifetime.

Thanks for your comments - I'm back to the drawing board.
