Relationship between the solar panel
output characteristics and the light
The maximum power point often changes due to different ambient temperature and lighting
conditions. Our MPPT controller can adjust the parameters from time to time according to different
conditions, so that the system is always near the maximum power point. The entire process is completely
automatic and does not require any adjustments by the user.
