That would be the epitome of overkill (like this reply :-), but yes!Power is energy/time, and that is what you need to charge your battery. Power is measured in Watts, which are equal to Volts * Amps. Saying "9 volts of power" is incorrect. If current (I) is zero, the voltage (V) can be anything, and the power is still zero. Current only flows if there is some connection and (non-infinite) resistance (R). Ohm's Law says that V = I * R. An IV curve is a graph of the current (I) versus voltage (V) for the solar panel. That curve changes depending on how much sun is hitting the panel (and also on several other things such as temperature). But once you have an IV curve for a given set of conditions, you can calculate the power (I*V) for any point on that curve. You can also calcul...
