What does Over-performance mean?

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.

However, 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
• Solar tracking systems

If you have received an over-performance email from us, and if you have your system details, you can update the details on the Dashboard using the instructions provided here. Alternatively, reply to your over-performance email and we'll estimate your system details to the best of our knowledge to provide you more accurate performance values.
