Solar Panel Testing: Output, Amps & Watts Euro caltech UAE

• Measure open circuit voltage (Voc) on a multimeter and compare to the panel's listed Voc.
• If negative, reverse the probes and measure again.
• If voltage and current measurements are similar, the panel is in good condition.
• Measure short circuit current (Isc) on the panel's specs label.
• Prep the multimeter to measure DC amps by moving the red probe to the amperage terminal and setting it to the amp setting (A).
• If the multimeter's current rating is greater than the panel's short circuit current, use a clamp meter.
• Place the panel outside in direct sunlight and use a towel to limit its output.
• Adjust the tilt angle of the solar panel until the max current reading is found.
• If the voltage and current measurements are similar to the panel's claimed Isc, the panel is in good working order.
