Our Story

Previously known as TJM Electrical & Solar, we grew up and live in Moreton Bay Region and realise exceptional service, good quality parts and superior workmanship is how we can best service our customers and ensure we are in business long-term

Moreton Bay Electrical Services

Based in Wamuran, Moreton Bay Region, Mern Industries was established in 2009 as TJM Electrical & Solar. Rebranding in 2021 to Mern Industries, this change more appropriately reflected the business’s growth and expansion to the variety of services we provide, along with it being part of our family name.

The business is still owned and directed by Tony with his wife Amanda who have a long history in the local community. They felt there was a need in the local community to access quality electrical, air conditioning and solar solutions for current residents and farmers as well as new families moving to the area.

They wanted to make people’s day-to-day living and working lives more comfortable and easier while giving a personalised, quality, value for money service.

What we do best

Tony has extensive experience in all aspects of electrical installations, air conditioning, telecommunications and fault finding. He is also a fully accredited solar designer and installer for grid connect solar, and solar system with battery back-up and has been installing solar since 2009.

Tony’s experience and skill in sheet metal fabrication also complements our services with custom-designed and manufactured steel covers, boxes and cages for safety and weather protection of inverters, air conditioners and the like. All of which are made locally, here in Wamuran.

As a team, Mern Industries want to exceed customer expectations. We also value our networks and partnerships with other local businesses to support jobs and skills in the Moreton Bay region.

We only supply and recommend reputable products from Electrical Wholesalers ensuring peace of mind regarding warranties.

What Our Customers Say


Very friendly and professional. No issue was an issue! I had a few questions and Tony listened and gave a resolution straight away. Provided honest genuine feedback. After getting screwed over by another company it was a relief to have these guys at my home. I’m kicking myself for not using them in the first place. Which is why they’re back to do more work for me. Excellent quality and value. Refreshing really!

Katrina Gould


We were more than happy with the service and we will be definitely using you again. We will 200% be recommending you to family and friends

Greg Oliffe


TJM Electrical & Solar replaced my solar panels and inverter following the failure of my original equipment. They were competitive in their quotes and offered a selection of high quality equipment from which to choose. Office support and service was excellent. Installation was fast, and conducted very efficiently. The installation team members were friendly and informative. Their advice on safety was relevant and clear. This firm sets a standard for which most should aspire.

Solar, Air conditioning

We would highly recommend Mern Industries. They came and tested our solar system as we were not creating any power. They replaced a cracked solar panel and the isolators and now it works! They also installed a new air-conditioning unit in the house. The team were highly professional and efficient cleaning up after themselves and taking away the damaged items. Thanks so much.

Mern Industries was referred to me by a family member during recent home renovations. I could not be more happy with the recommendation.
During what was an extremely stressful time managing a wide range of trades Mern Industries was there to help, they turned up on time, helped me understand the impacts of my decisions and their work is of a very high standard.
We are so pleased with their work that we have continued to use their services on other repairs around our home and highly recommend them to family and friends.
