Simple steps for simple living

Making the commitment to install a solar system can be complicated, but with us, it doesn’t have to be. Our streamlined processes make the transition to solar as easy as possible, so you can finally take charge of your own energy.

  • Consultation


    Our first step is to conduct a detailed consultation process with you or your project manager. A clear understanding of your property, physical assets and unique energy consumption profile is paramount in formulating a bespoke, cost-efficient solar solution.

    Everyone uses energy differently. That’s why we take the time to get to know each unique project, taking the guesswork out of choosing system components.

  • System Design

    System Design

    Our experts will request a number of documents related to your home or business and energy consumption profile. This information allows us to tailor a unique solution for you, completely customised to maximise your return on investment.

    Solar shouldn’t be a ‘one-size-fits-all’ solution. The most efficient and safest systems are designed specifically for the location and anticipated usage.

  • Installation


    Our team takes the greatest care to get this vital step in the process right. We’ll ensure your system is installed safely, securely and in the most effective manner. Plus, we hold the highest solar accreditations in Australia to offer you more peace of mind.

    Working with electricity is no joke. You can relax, safe in the knowledge that our team has the qualifications, know-how and experience to do the job right.

  • Monitoring


    We closely monitor your system’s performance to ensure it’s operating as planned. If a rare fault occurs, we will dispatch a technician immediately without any action required from you. This ensures maximum energy production with minimal downtime.

    Who needs the hassle of chasing a repair person? We often notice a system needs attention before our clients do and despatch an electrician to fix any faults.

Don’t stress over solar!
We do all the hard work for you!

We’ve totally streamlined the process from start to finish, so everything is as simple as possible for you.
