Hi Emily, This part isn’t designed to be used for solar charging, you would need to look at https://www.sparkfun.com/products/12885 which we don’t stock. Also we don’t advise creating a circuit to charge a mobile phone as if the circuit isn’t correctly wired it can damage the unit and/or phone.
Hi, the JST connector on this board is female so it's correct for a battery but not for most devices. We don't sell a male to male JST connector at the moment.
For the second question, the board itself will store little if any charge. It is designed for charging a LiPo cell.
If I've misunderstood your question please let me know.
