Solar power generation has voltage but no current
This means your solar panel is generating voltage (open circuit), but the circuit is incomplete and therefore cannot generate current. This could be due to a loose or broken wire, a faulty inverter or charge controller, a poor connection, or an internal problem with the panel. Now, let's understand the most common causes of this problem, the correct. Another way to describe the problem, is loading the solar panel down produces little to no power.
