Hielscher Electrical and Solar Cairns

We had a fantastic experience with Hielscher Electrical and Solar. Brenton and his team were professional, efficient, and easy to work with from start to finish. They took the time to explain everything clearly and made the entire process smooth and stress-free. The team installed our solar and energy storage system and replaced our old switchboard with a new one—all completed in a single day. The workmanship was excellent, and they left everything neat and tidy once the job was done. We’re extremely happy with the result and would highly recommend Brenton and the team at Hielscher Electrical and Solar to anyone considering solar or electrical upgrades.

A smooth, easy transaction with admin staff providing polite, courteous & timely updates on progress. Installers were prompt, thorough & helpful. The overall interaction was efficient & professional. Very happy & satisfied with the outcome.

I would give 10 stars if I could! We recently had 2 towers of Fronius batteries added to our existing solar system 13.6kW by Hielscher Electrical. The owner Brandon Hielscher is incredibly knowledgeable about the different inverters and batteries brands, guiding us toward a premium option. The Installation was done professional by Brenton and a team member, and the system works exceptional well. I highly recommend Hielscher Electrical and would use them definitely again. From a very happy customer

Hielscher recently helped us with our Solar and Battery install on a property with decromastic roof tiles. They were brilliant from start to finish, from a great site visit and quote, to keeping me in the loop right up to installation. The installation is super neat and professional and includes everything we want from the system which has also been working amazingly since it was installed. Couldn’t recommend them enough.

Had a 20kW Longi + Sigenergy SigenStor solar/battery system installed by Hielscher Electrical in Cairns early Feb 2026. Professional from quote to finish – clear comms, smooth Ergon process, neat work. Install day was hot/rainy but they powered through professionally and got it done. System performs great: batteries full by midday, the system is sized perfect for our needs and usage. I rarely leave reviews – only do it for businesses I’d genuinely recommend as a local – and these guys have earned 5 stars.

From initial quote through to installation, dealing with Hielscher Electrical has been stress free and an absolute pleasure! Professional and courteous. The service, communication and workmanship throughout the process has been exceptional. Highly recommended for anyone looking to install solar and battery!
