What can I do with this solar panel? Can I use it with electronics?
There is no practical use for 10 Watt Solar Panels other than maintaining 12 Volt Starter, Marine and Deep Cycle batteries over an extended period of time (several weeks and longer), which must be accompanied by a Solar Charge Controller.
A Solar Charge Controller is a conduit necessary to properly charge wet batteries; a reverse-blocking diode installed on a solar panel only prevents energy from the battery being sent back to the panel, not other functions such as properly regulating charging voltage.
Despite claims some manufacturers and retailers make, 10 Watt Solar Panels of any kind cannot be used for anything else as they do not produce enough power.
