To begin measure solar panel amperage.

How to check a solar panel for cracks.

Then touch the multi meter s black negative lead to your solar panel s negative wire. Micro cracks visible with electro luminescence el test. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight. These are the types of accidents solar panel owners want to avoid in order to continue having effective and efficient solar power systems.

The quick and easy way to clean your panels is a quick spray with a hose but be cautious. If it s not there is a problem with your solar panel output. You will need a solar panel tester known as an amp meter. Spraying hot panels with cold water can cause damage and cracks to your panels that cannot be repaired.

As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively. To measure the amp output of your solar panel you will need to attach the meter to the positive and negative. El testing is a process that makes use of image analysis and measurement which enables sight directly into the solar cells to locate inherent potential defects. Disconnect the positive cable that is.

Set the multimeter to 10 amps. Micro cracks may have various defect origins and result in rather soft outcomes such as yield reducing shattering of parts of the affected cell up to mores severe impacts involving decreases of the short circuit current and cell efficiency. In such a situation images of suspected panels are taken with specialized silicon cooled ccd cameras and these images are enhanced using fuzzy logic to identify cracks. That being done connect the solar panel to the controller and also the controller to the solar batteries.

Make sure that the alligator clips are in the right port to find the. Step 3 measure current. To get an accurate measurement you will need to ensure that your panel is in full sunlight when you test. Set the measurements of the multimeter to dc amps.
