Top quality installers
We chose DeIonno from three referred by Solar quotes as the salesperson was the most thorough and helpful. All three quotes were within a few hundred dollars of each so price wasnt the determining factor.Installation was earlier than expected and the electricians timely, thorough, tidy and professional. Post install support was needed to adjust system pending connection to Amber Smartshift which occured over just two days as a i was an existing Amber customer. The 8kw panel system is generating 40kw of energy on these hot sunny days and a truer test will come in the cloudy rainy winter months. The 16kw battery is being fully charged before midday on these sunny days.
After one year i will be clearer on system efficiency and whether payback period is likely to be in the estimated period.

I will never use them again!
Many issues and damage to my property which I have had to fix myself.Supplier Reply:
Hi Damien,Thanks for taking the time to leave feedback. We’re disappointed to read this, as it doesn’t reflect how the project progressed from our side.
Up until the final stages of the job, you had indicated you were happy with the installation and the work completed. The concerns escalated only once additional works outside the agreed scope were requested to be completed at no cost, which we weren’t able to agree to.
This was a large and complex system (over 30kW), and our team spent over a week on site completing the works. The solar and electrical installation itself was completed in line with the agreed scope and applicable standards.
A number of the issues raised relate to existing building and structural items that became apparent during or after the installation, particularly around the garage roof and skylight area. These were not caused by our team and were identified as pre-existing construction issues that require attention from a builder or carpenter, which was communicated at the time.
Where genuine issues were identified, we offered to return to site and address them, and we did attend to complete outstanding items. Some items were also rectified by yourself before our return visit, despite us advising that we would handle them.
It’s unfortunate the situation escalated the way it did, as we were actively trying to work toward a fair resolution. While we don’t agree with several of the statements made, we respect your right to share your experience.
We stand by the quality of our work and the professionalism of our team, and we encourage anyone considering Deionno Electrical & Solar to contact us directly if they have questions around scope, inclusions, or system design before installation.

Battery and gateway installation.
The actual installation was carried out quickly and staff were cooperative and polite. However, when I queried the suitability of the mains connection and breaker sizing I was repeatedly told there was no problem. Well it turns out there is a problem because I cannot charge the battery and run appliances concurrently and after asking them to quote to rectify the problem, they chose not to return calls. There was also a problem with them putting their details into the system so I could actually use its features. After initially denying there was a problem they looked further and discovered there actually was an issue, it was quickly rectified. The company seems predominately focussed on getting in and getting out as quickly as possible and is dismissive of anything that may hinder that. Several contractors have inspected the installation and acknowledged the need for an upgrade but ultimately have declined the work. At least one said the work should have been carried out during the battery installation. I will continue my quest to find a contractor.Inverter rating: 5/5

Great experience for total novices
My husband and I were impressed by Deionno Group from the start with the sales person who had all the answers to our questions ( there was a lot ) his patience and honesty, we didn’t need as big a system as originally thought from info we supplied when asking for a quote.There was great communication both before and during our experience.
There was a slight hitch ( panels not available ) but they definitely offered an advantageous ( to us ) solution that we were more than happy with.
They were punctual and left the areas very tidy. They provided information and set up for the website to monitor the solar and tried to help with our internet problem, which had nothing to do with the installation.
I would strongly recommend Deionno Group to anyone, especially those not sure if it is for them , and looking for a solar set up.
Our system was up and running straight away and the battery was charged hours before the end of the day ready to use that night.

Fantastic Transition to Solar Batteries
They came. They listened. They understood.They provided proven experience and quality products to match our needs. Their advise was respectful to our needs and SAPN and spot on.
We even managed to retain our existing solar system. And incorporated our exiting J tariff HW system into the new gateway.
Installation team were excellent. Great bunch of guys all willing to do the best job and talked to each other to resolve any issues. Board was rewired with new breakers and if very neat and clean.
System installed now for two days, batteries are fully charged and to date no power from grid!! In fact still managing to export to grid!! Happy days I think!!
Great experience from start to finish
We had a good experience with Deionno Electrical and Solar. Everyone we have connected with has been friendly, professional and helpful, including for quoting, booking the install, the actual install and invoicing. The team who did the install were punctual and friendly. They look to have done a great job with the panels, inverter and battery and it all looks neat and tidy. They cleaned up after themselves. They checked in with me throughout the day and then explained how to use the app to monitor the system. They also showed me a photo of where the panels were. We have received a few check in messages to make sure everything is working well which makes us feel like valued customers not just a number.Panel rating: 4/5
Inverter rating: 5/5
Battery rating: 5/5
