any solar panel that can recharge batteries?

[picard]

Is there any solar panel that can recharge the lithium ion batteries? perhaps a current adapter that can convert the current suitable for lithium ion batteries.

not much of an expert...

but solar cells output raw power that varies both in voltage and current depending on what was the sun conditions at the time, hence why low wattage photovoltiac [PV] modules use a series parallel connection of cells to create an output around 12V and uses it as trickle chargers for less sensitive cells including but not limited to sealed/flooded lead acids.

I think lithium ion cells require a constant current/voltage input for safely charge them, which means you will need an charger circuit to go with your solar panel, I suppose since most stock lithium ion chargers uses DC through an AC/DC step down you could size your solar cell relative to your charger's requirements and again a circuit may be required to prevent over current/voltage during full sun and a boost for the partial/overcast sun conditions....

I think something like this might work [theres other, more cheaper ideas also]
solar cell + stepdown [assuming the stepdown transformer has an output current relative to what your lithium charger can support]

hope this helps
IF ANY EXPERTS FIND ANY ERROR IN WHAT I WROTE PLEASE TELL ME

I'd like to experiment with this general idea myself and will. Let us know your results please
