There is a good chance that you may see there is voltage but no amp (which means current). Why? Solar panels having voltage and no amps are mostly caused by an open circuit. In simple terms, it means your circuit is incomplete or flawed. Causes include using wrong voltage, wrong Connection, problems with panels or solar charge controller.
Current always flows from a low voltage to a high voltage. With this in mind, it should be clear that if your load voltage (the voltage of the equipment your panel is connected to) is higher than your solar panel’s voltage, then your current will have nowhere to flow as this path has been reversed.
Another way Open Circuit happens is using more Load Voltage than panel voltage. As said earlier current always flows from high voltage to low voltage. When the voltage of your load (Load is something you connect to Solar Panel. Take Battery for Example) exceeds your panel’s volt current would not flow from the panel. It’ll be reversed.
The article addresses a common issue where a solar panel shows voltage but no current (amps), leading to a malfunction in the system. It discusses the diagnostic process, including checking standard ratings and setting up the panels for optimal sunlight.
Low solar panel voltage can be due to various factors, such as shading or defective panels, which require diagnosis and repair for better performance. When solar panels fail to produce the required voltage, your energy generation is disrupted.
Your Solar Panel Circuit has a lot of equipment. One of the main pieces of equipment is Solar Charge Controller. Now if it is broken your entire circuit will be busted. In the worst-case scenario, the current will stop flowing. Thus there will be zero amps despite voltage. Usually, low-quality charge controllers have this problem.
