How to test a 5 watt solar panel.

Measure the resistance of the electrical circuit in ohms and write down this value. That being done connect the solar panel to the controller and also the controller to the solar batteries. Disconnect the solar panel from the circuit and switch the digital multimeter to measuring resistance. Disconnect the positive cable that is.

In this test a multimeter will be the best tool to know the volt and amps of your solar panel. Make sure that the alligator clips are in the right port to find the. The latter is preferred as it has more added qualities. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.

To measure the amp output of your solar panel you will need to attach the meter to the positive and negative. Touch the multi meter s red positive lead to your solar panel s positive wire. After laying the solar panel in an area receiving direct unadulterated unblocked sunlight take a look at your multimeter and set it to volts. Set the measurements of the multimeter to dc amps.

You will need a solar panel tester known as an amp meter. If it s not there is a problem with your solar panel output. The volt reading on your multi meter should be close to or just under 60 volts. 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.

Results will vary depending on sun strength time of day angle of light and temperatu. To begin measure solar panel amperage. Some exceptions may apply based on panel type. Set the multimeter to 10 amps.

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. Measuring the volts and amps of your solar panel using a multimeter. The first test you ll want to perform using your multimeter and solar panel is that of voltage. There are two types of multimeters.

Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. Analogue and digital multimeter. Since electric current is measured in amperes you will need to buy a meter known as an amp meter and measure the output.
