This is simply a solar cell connected in parallel with a load and a multimeter set to measure.
Meter to measure solar panel output.
Note positive negative connections.
Standard test conditions for solar panel wattage would mean your solar panel is operating at 77 degrees fahrenheit while there are 1000 watts of sunlight per square meter hitting the panel.
Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts with higher power ratings generally considered preferable to lower power ratings.
Step 2 measure amperage since electric current is measured in amperes you will need to buy a meter known as an amp meter and measure the output.
So under these ideal conditions a 250 watt solar panel will produce 250 watts of electricity.
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.
That being done connect the solar panel to the controller and also the controller to the solar batteries.
Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v.
Using a multimeter for solar panel tests step 1.
Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal sunlight and temperature conditions.
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 to read up to 200 volts to ensure that you receive an accurate reading.
Hook it all up.
Disconnect the positive cable that is.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
Locate the converter box.
A good quality multimeter that can read voltage.
The stc measure the solar panel s energy output using common conditions of light exposure orientation and panel temperature.
Set the multimeter to 10 amps.

Set the measurements of the multimeter to dc amps.
How to measure a solar cell s power output.
A solar cell or solar panel to test.
The converter box is located on the back of the solar panel.
