Now that out of the way, it depends upon which type of system of which you want to measure the Short Circuit Current. If it’s a full-blown solar array then stop and don’t even attempt to measure short circuit current. And if it’s a Single Panel you can do it without worry.
Remove the towel and read the current on your multimeter. Adjust the tilt angle of your solar panel until you find the max current reading and compare this number to the short circuit current (Isc) listed on the back of your panel. The short circuit current you’re measuring should be close to the one listed on the back of the panel.
Semiconductors are affected by temperature. And in high temperatures, the current carrying capacity of the module goes down and problems may occur. 59 Degrees to 95 Degree is a good range for Solar Panel. Why should you measure Solar Panel Short Circuit Current?
When you connect both ends of your panel and create a short circuit connection what ends up happening is the voltage across your solar cells become zero. Short circuit current is actually the largest amount of current that can be drawn out of your panel. So it’s quite important to measure it for safety purposes.
Short Circuit is not a natural situation and is only done for short circuit analysis. Get rid of the short circuit as soon as you finished your tests. Be careful of Radiation and Temperature. Most solar module can take 1000 W/sq.cm radiation. Be sure your weather is compatible. And always avoid high temperatures.
Note: You can more easily measure PV current by using a clamp meter, which I discuss below in method #2. That’s right — you can use a multimeter to measure how much current your solar panel is outputting. However, to do so your solar panel needs to be connected to your solar system.
