My electricity bills have increased significantly above my normal, does that mean something is wrong with my solar system?

1. To check this you should check the system performance - Go to the system’s production monitoring system and look at the generation right now and check it against what the system should be generating (you can use Solcast for this).
2. If there is an issue with the performance then it is best to contact your solar provider to help detect the fault.
