Mark Group Guarantee

We design, build and install quality high output and reliable solutions at fair prices that deliver great value for many years. Our promise is that we will plan a system that is approved by you every step of the way before installation begins and that we will educate and partner with you through the entire process.


Our approach is beyond the one product solution. We take a consultative approach to understanding the outcomes you are wanting to achieve for your project.


Our accredited team of designers will take into account your roof and environmental conditions to maximise the output potential of your solution


Mark Group is one of Australia’s largest installers of rooftop solar systems. We train installers in our own Mark Academy and we take responsibility for all our installations with a 10-year workmanship warranty.


We offer our customers dedicated after installation support. We provide a single point of contact for all service and warranty requests. We have direct partner relationships with all our manufacturers, which includes local warehousing to fast track service response times.

Reduce your electricity bill

  • Renewable energy

    Advances in solar power technology are giving you great control over your power bill now and increasingly into the future.

  • Heating and Cooling

    Watch out for the cost of gas heating. Gas is now ramping up to world pricing. Electric based heaters and air conditions are already expensive.

    Talk to us about our natural wind powered cooling and warming solution. It has an operating cost from just $35 per year.

    Check your roof insulation. If it’s older than 6 years, it’s most probably under rated to current standards and possibly degraded. It will need a top up. Talk to us about our insulation top-up service.

  • Energy Efficient Appliances

    Your old 10 year plus appliances are burning a hole in your household budget. Get rid of that old fridge in your garage. It could be accounting for up to 20 per cent of your power bill!

  • Behavioural Change

    Watch out for appliances on standby – When not in use for a long stretch turn off TVs and microwaves. Also chargers for wireless phones and electric toothbrushes. Consider intelligent power point or power box adaptors.
