i guess your battery is a lituium ion 3-4.25V with protection circuit. Solar cell is unknown, only 7V and quite high internal resistance, but must be very small. it needs more information, anyway, i like to use constant sources to emulate any battery condition in voltage and check the current. Check this as a first approximation http://everycircuit.com/circuit/5878709882716160
