Video related to this blog post: Solar Panel makes no power! But has Voltage? Another way to describe the problem, is loading the solar panel down produces little to no power. As soon as a load is placed on the panel, the voltage drops significantly, but no power is produced.
These are actually common problems and there are ways you can fix them. A faulty inverter or charge controller are the most likely reasons for a solar panel to register no voltage. Other possible reasons for low to zero power are a damaged PV module, poor wiring, shading and temperature higher than the ideal operating range.
If you have an MPPT charge controller connected to the solar panel, it might sweep the panels for MPPT (max power point) and show the solar panel voltage drop as you normally expect when the panels start supplying power – yet in this case, no current flows into the battery. So the charge controller is unable to charge the battery.
When you have a bad connection, it could manifest as follows: wires and connections heating up, low power output, or even NO power output at all. So the first thing I'd check on a solar panel that drops its voltage but does not output any power (current) is obviously the MC-4 connectors.
