To measure the amp output of your solar panel you will need to attach the meter to the positive and negative.
How to test solar panel amp output.
You need to have a panel tester that is known as an amp meter.
To determine the power that the solar panel is dissipating you need to measure the wattage and voltage.
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.
To begin measure solar panel amperage.
Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
Measure solar panel amperage.
Whenever you have these two values you can figure out the wattage by multiplying them together.
As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.
Attach the meter to the positive and negative so that you measure the amp output of your solar panels.
To get an accurate measurement you will need to ensure that your panel is in full sunlight when you test.
