Q1: Why does the 100W solar panel cannot provide 70W of output power?
A: The actual output power will be affected by many factors such as weather, temperature, sunlight intensity, and the panel 's angle. The 70W of power is the result under international standard of outdoor testing conditions :1000W/m,AM1.5,25°C (IEC60904) . So it is normal that the actual power does not reach the rated power , and the output power will constantly changes with the rotation of the sun. To get a higher output wattage , please use it under stronger sunlight , adjust the angle , and avoid the shadow.
