You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel.
How to test a 6 volt solar panel.
Testing the 12 volt solar panel.
As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively.
See how to test your solar panel for open voltage and current reading.
Results will vary depending on sun strength time of day angle of light and temperatu.
Testing your solar panel is easy.
Some exceptions may apply based on panel type.
To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading.
All you need is a multimeter.
If you need a multimeter you can get the innova 3320 auto ranging digital multimeter here htt.
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.
Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.
Step 3 measure current.
The solar panel will trickle charge your 6 volt battery during the day.
Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight.
As most solar panels are 12 volts the solar panel test methods are basically the same.
Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
To test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting.
Then run wires from the battery to the charge connector making sure to match the positive and negative poles.
