Having faulty wiring can lead to all sorts of problems, and this could also be a reason why your solar panel voltage is low. Imagine having a loose wire, not only could it start a fire, but it can also disrupt how much voltage your system makes.
A problem that a DIY solar power enthusiast may someday face is to find a solar panel [or a whole solar panel array] has good output voltage – but does not produce any power when connected to a charge controller.

Additionally, investigate whether your solar panel is shaded by trees or objects, obstructed by dirt, or physically damaged. Examine the MC4 cable and the junction box to confirm proper connections. By following these steps, you’ll be well on your way to identifying and addressing the low voltage issue in your solar panel system.
A properly set up wiring system not only keeps things safe but also makes your system work better. So, if you’re noticing a drop in voltage, faulty wiring might be the main issue to blame. For a better understanding of wiring and cables, check out Solar Cable Size Selection Guide For PV Plants.
