Your system is 'over-performing' if your site is performing above the normal range.
A little bit of over-performance just means your system was well designed and performs slightly better than we expect.
But a large over-performance probably means something is wrong in the information regarding your solar system. Possible causes include:
- Incorrect inverter or modules specifications
- Incorrect number of modules or strings or sub-arrays
- Incorrect array tilt or orientation
- Incorrect system location
Please check these details by visiting the 'My Site' page on your Dashboard and let us know if anything is incorrect.
