Many people want to know what the testing standards of solar panel are, and how to check them? Then the editor will tell you now.

1. Open circuit voltage: Use a 500W halogen tungsten lamp, a 0-250V AC transformer, the light intensity is set to 38,000-40,000 LUX, the distance between the lamp and the test bench is about 15-20CM, and the direct test value is the open circuit voltage.

2. Short-circuit current: Use a 500W halogen tungsten lamp, a 0-250V AC transformer, and set the light intensity to 38,000-40,000 LUX. The distance between the lamp and the test bench is about 15-20CM, and the direct test value is the short-circuit current.

3. Working voltage: use a 500W halogen lamp, a 0-250V AC transformer, the light intensity is set to 38,000-40,000 LUX, the distance between the lamp and the test bench is about 15-20CM, and the positive and negative poles are connected in parallel. Resistance, (calculation of resistance value, R=U/I), the test value is the working voltage.

Fourth, the working current, using a 500W halogen lamp, a 0-250V AC transformer, the light intensity is set to 38,000-40,000 LUX, the distance between the lamp and the test bench is about 15-20CM, and the positive and negative poles are connected in series. Resistance, (calculation of resistance value, R=U/I), test value is working current
