Hi,
Another team member here passing by.
Very interesting concept, however, I did find I few notes on it.
How confident are you that the potential solution would gain enough energy from the solar panels for the given purpose?
In addition to that, it is important to consider the usability of such connections at that point of wireless communication development around the world. Is StarLink by SpaceX for example not a better solution? If so, the portable solar panel could be used for powering these ground station elements.
All and all I do believe that the presented concept of a portable solar panel is an interesting one especially given the presence of a high yearly solar energy density average in such continents as Africa, however, I do suggest taking into account the concerns raised for the final solution.
Best of luck!
