If there is no current in the solar panel, 1. . solar panels make voltage but no current Assuming that the modules are not defective and that they are exposed to sunlight, then there is a very simple answer: There is no conductive connection between the modules. Solar modules don't. . Open circuit voltage and short circuit voltages can be correct on a defective panel. With lamp as a load, you can measure voltage across each bypass diode. No current means no power production, and frankly, no paycheck from your net metering program. ensure proper sunlight exposure, and 4. The relationship between voltage and. .
