What customers say

Based on genuine customer reviews

Starting from the first site visit and continuing through to system commissioning, feedback about this Darwin solar and electrical company centres on a process that customers found well organised and straightforward. Installation crews are repeatedly praised for efficiency and punctuality, with a larger 17 kW job singled out for the calibre of the team on site and the smoothness of the day itself. Guidance offered during the application stage, particularly around network and utility dealings, comes up often, and staff are noted for answering questions promptly and knowing their subject matter.

Jack, from the solar division, is named for assisting when a fault emerged, while the components chosen and the ongoing support after handover also attract comment. Accounts include energy retailing transfers completed without fuss and a defective inverter that was eventually replaced by its manufacturer. Reviewers regularly draw attention to the difference the systems make to running costs, with one household in credit and another reporting a steep drop in monthly billing. The considerate, knowledgeable service and individual attention given to each job characterise what is described.

I was very impressed by the quality of work and the efficiency of my Rimfire installation. The people I communicated with were friendly and knowledgeable. Once they started, the installation only took 2 days with very little disruption to my wife and I. The cost of the installation was very reasonable.

A heads up to people don't use Rimfire energy! We have had nothing but trouble from the start, from damaging our roof when installing it. Which we had to have the panels taken off and parts of our roof re sheeted. In 24 months of having the solar, 4 inverters have stopped working. It has taken 6-18 weeks each time to have the issue sorted. We are currently at 18 weeks with a system that doesn't work. We were asked to re agree to a new contract that they take no responsibility for our system if it fails again. They don't answer their phones or give you honest answers when they do. Multiple times have caught them trying to lie and make excuses. This company should not be running, a complete failure.

Rimfire put my solar on in May 2023. They have always been really helpful and professional. I get a much better feed in tariff rate than people in Jacana. I recently had a problem and Jack from the solar area helped me big time. I would recommend them. They can come and talk to you so then you can find out for yourself ☺️☺️

The service was excellent, and the installation was completed quickly. We previously had 6 kW panels installed on the roof, and Rim Fire has now added another 6 kW of panels, along with a 16 kW battery. We are extremely pleased with the results.

Very good experience with installation and providing an energy retailing service for a small business solar system. We did have issues with a defective inverter but the supplier eventually replaced it though rather slowly.

First month of full use and I am in credit. Excellent company to deal with, you get answers straight away by people that actually know what they are talking about.
