from the above conclusion discussion . i think you add another solar panel parallel of the same voltage same wattage or more watt keeping the same voltage . then i think the circuit should . because the battery is soaking the current more or there is huge loss of ampre and hence the voltage is dropping . so please do this little modification i hope the project will act fine . keeping all the things intact.
