I don't really have much need to deal directly with you, but when I have it has been a pleasant experience.
The introduction of an app or web service that shows how much electricity I am generating and using by the hour would be good.

I am not satisfied with the ratio of feed-in-tariff to supply tariff.
Historical costs for power to site include ~$14k in the underground cabling beyond the boundary to the network plus ~$7k in solar panels.
Our 18 panels generate virtually all the power used annually by a household of 4 adults.
It is my view that my quarterly bill should be negligible.
Since the installation of our solar, the initial drop in quarterly costs has crept up to a level comparable with those prior to the installation.
Our supply costs are the subject of ongoing review.

Reason for Average Rating
Yes, I am relatively happy with the services from Diamond energy, but am somewhat disappointed that my Bill keeps going up, regardless of the fact that I Installed a (small-ish) PV system of 2.6 KW.

If you want to save money change to Diamond Energy.
We changed to Diamond Energy 4 years ago. During this time the savings from our previous supplier and increased savings from Diamond Energy on our electricity bill have enabled us to recovered the compete cost of our solar panels. 4 years ago we replaced our upright hot water system with a on roof solar solar system and as our solar panels have been paid for and combining the hot water solar panels savings with our other solar panels savings expect to recover the full cost of the system on the next power bill.
We know the above is fact as we kept a spread sheet on every bill for the last 8 years with all details laid out.
