How to test solar panel amp output.

You need to have a panel tester that is known as an amp meter. To begin measure solar panel amperage. To determine the power that the solar panel is dissipating you need to measure the wattage and voltage. Measure solar panel amperage.

To test a 18v solar panel voltage output directly put your solar panel in direct sunlight set your multi meter to the dc volts setting. Whenever you have these two values you can figure out the wattage by multiplying them together. You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit this means that if you have a panel rated for 20 volts you should set the multi meter. As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.

To get an accurate measurement you will need to ensure that your panel is in full sunlight when you test. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
