As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.
How to test solar panel amp output.
Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
Attach the meter to the positive and negative so that you measure the amp output of your solar panels.
After doing your solar panel testing you should find that the solar panel output for the pv panel you built on the make solar panels page is about 18 volts and 3 5 amps.
Measure solar panel amperage.
You need to have a panel tester that is known as an amp meter.
To begin measure solar panel amperage.
To get an accurate measurement you will need to ensure that your panel is in full sunlight when you test.
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.
Whenever you have these two values you can figure out the wattage by multiplying them together.
