Was really surprised with the efficiency and skills displayed with the installation of our battery and rewiring/extension of solar panels. System is working well and have not had to access the grid so far (5 weeks). The team answered all of the questions I threw at them and were very neat and professional. The app is now one of the most used on my phone. Thanks everyone, cheersPosted on Google![]()

From start to finish, the team at Halcol were fantastic to deal with. The quoting was easy and inspired confidence. Nathan was patient with our many questions and always happy to explain things. When installation day came, the crew were fast and efficient and explained everything clearly. The whole experience was positive and I can’t recommend Halcol enough.Posted on Google![]()

I could not be more happier with Holcol Energy. They were very professional in all aspects doing their job. I recommend Halcol for home battery and Roof solar panels. The boys explained the phone app.exceptionally well. Staff in the front office are very friendly and could not be more helpful.Posted on Google![]()

Recently had a solar and battery system installed by Halcol. The entire process was streamlined and so easy. The installation and the technicians doing the install were very experienced, totally professional and explained the workings of the system very well. I would recommend anyone looking to install either a solar or battery system to include Halcol in your inquires. Once again thank you.Posted on Google![]()
