1. Open circuit voltage: use 500W tungsten halogen lamp, 0~250V AC transformer, the light intensity is set to 3.8~4.0 million LUX, the distance between the lamp and the test platform is about 15-20CM, and the direct test value is the open circuit voltage;
Second, short-circuit current: use 500W tungsten halogen lamp, 0~250V AC transformer, the light intensity is set to 3.8~4.0 million LUX, the distance between the lamp and the test platform is about 15-20CM, and the direct test value is short-circuit current;
Third, the working voltage: with 500W tungsten halogen lamp, 0~250V AC transformer, the light intensity is set to 3.8~4.0 million LUX, the distance between the lamp and the test platform 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;
4. Working current: use 500W tungsten halogen lamp, 0~250V AC transformer, the light intensity is set to 3.8~4.0 million LUX, the distance between the lamp and the test platform is about 15-20CM, and a corresponding resistance is connected in series, ( Calculation of resistance value: R=U/I), the test value is the working current;
Solar parameters and indicators knowledge
Q: Can solar panels generate electricity on cloudy or fluorescent lights?
A: The exact statement is that it produces a small amount of current, which can basically be said to be negligible.
