Professional service
Service from start to finish was very streamlined, no stress whatsoever.We were kept informed throughout the whole process, and the installation itself was brilliant, wonderful friendly workers who left no mess, you wouldn't have known they were here. A great company who certainly know how to communicate and look after their customers.

Great Solar Experience
From the quoting to the installation, we were very happy with Deionno Electrical and Solar. Along with Humming Plumbing they looked after every aspect of our solar experience - from removing our old hot water system and installing a new one, to adding additional panels and a battery. The installation team stepped us through every aspect including the app.Deionno looked after the grid connection, so there was very little for us to do.
The crew were all great. Happy to recommend this group.
Great service start to finish
Very happy with the level of service provided from the initial quote to the installation of the battery. Everyone was approachable and efficient and kept us informed throughout the entire process. Very impressed with the installers who made sure all packaging was cleared away and swept up any mess. This service was recommended to us by friends and we would certainly recommend the company to anyone else.
