Diamond energy, no energy to fix issues

Not a happy customer


There is no point calling their customer service as they don't seem to do anything. Requested to change over to them asap to get the most out of my new solar panels with extra cost involved. Complete mess up, finally connected after 3 months. I feel that I have been very clear with what I wanted. But they have no provide me with what I am expecting.

Not their problem.


Company failed to call and let me know my power had failed to shut off. Then received a 200 dollar bill 3 months later after bein told my account was closed. I was required to pay plus extra disconnection fees. No courtesy or accountability. Would not recommend.

Should I only go with Diamond Energy if I have solar panels? I am moving out and will be renting so we won't have solar, will it still be a reasonable price?

1 answer

I think they do a bill compare if you ask them. They did it for us. They're good even with no solar.


I'm looking at Diamond Energy, I'm in an apartment so trying to work out whether I need solar panels or not?

1 answer

It would be tricky to get solar panels in an apartment but Diamond energy is sourced from renewables, so at least you know you're helping the planet!

Is it more expensive to have solar on private rentals than owning you own home?

3 answers

I can only speculate, that as a tenant, after getting the owner's agreement to install panels, if indeed you are responsible for the electricity bill as most tenants in Australia are, you would earn as much credit for the electricity your panels generate as an owner would, but without the security of tenure an owner has, you will have the extra costs of uninstalling, taking the system with you and reinstalling on your next rental property...if you can find an owner who agrees to it.


We have solar panels, a 5kw system.
Diamond energy give us 11cents per kw put back into the grid.
But I think the main benefit is that with solar it uses the power generated for the home use first then any excess going back into the grid.
My bills have more than halved since installing solar.
Try using your heavy electricity usage between 9am and 2pm if possible, that is the maximum gain period for solar.
I must admit I have not heard of anyone taking the solar installation with them when they move.
The way new technology is going, there will be bigger and better all the time.
Hope that helps you.

If your bill is 800 plus you may benefit. Personally I would go halves with the owner and only if your bill is really high
