How does a partial solar eclipse impact the production of solar panels?

Many South Africans had their eyes on the sun today as they took the opportunity to experience a partial solar eclipse when the moon glided between the Earth and the sun. This incredible event takes place every 18 months however it is only visible from certain parts of the Earth during each cycle. The graph below shows the output power from one of our operation sites – interesting to note that while there was a significant dip in production during the eclipse, as it was a partial eclipse the system was still able to continue producing energy utilising the available (lower) irradiance.
