Wiring thatís too small would not account for such a poor performance.
Your output is too low(at least half what it should be) for there not to be a more fundamental fault.
Some details of your system would really help.
Troubleshooting is not difficult the output from each panel can be measured and the regulator
bypassed. This will isolate where the fault lies.
The steps that should be taken are.
Measure the current
from each panel (Full sun and depleted batteries are better). This is easy with a clamp on multimeter.
Measure the voltage drop to see if there is a bad connection
If the panels are wired in parallel (If your regulator
is not MPPT
they must be wired this way) connect the array directly to the batteries and measure the current
this will tell you if the regulator is defective.
These steps can be done with very little electrical
knowledge. I am sure we can talk you through the details. They can be done with a simple multimeter, but a clamp on multimeter makes it much easier (about $75) and will be useful for other electrical
