Hello,

BQ25505EVM is an evaluation module for the BQ25505 IC.

You can use either a power supply with series resistor to simulate a solar panel, or you can use a real solar panel to power up the the board.

There is no specific type of Li-ion battery suggestion. Any 1s Li-ion battery can be used for the storage.

Yes. One note, the max charge current of bq25505 is ~100mA. Assuming your input source is able to provide max current, then your battery is going to be charged at 0.2C rate max.
