Residential Solar Installation

Residential solar is a practical way to lower daytime power costs and get more control over your household energy use. We design each system around your roof layout, energy habits, and budget, so you get a setup that fits the property.


With residential solar installation, you can expect:

  • System design to suit your roof and usage
  • Quality solar panels and inverters from proven brands
  • Safe integration with your existing electrical system
  • Clean installation by licensed electricians
  • Support with connection paperwork


If you’d like to store excess solar power for evening use, we can also discuss battery storage as part of the design.

Commercial Solar Installation

For many businesses, commercial solar is a straight business decision. Lower power costs can improve cash flow, reduce overheads, and make better use of available roof space. O’Brien Kontrols installs commercial solar in Perth for offices, workshops, warehouses, and larger facilities. We design systems around your daytime load, operating hours, and site layout so the system matches the way your business actually uses energy.


Commercial solar can help with:

  • Lower electricity costs
  • Reduced reliance on grid power during the day
  • Better use of available roof space
  • Scalable system design for growing energy needs
  • Long-term savings across the life of the system


For some sites, battery storage can also be worth considering as part of a broader energy strategy.

Solar Rebates & Grid Connection In WA

Eligible residential and small business solar systems can receive value through Small-scale Technology Certificates, commonly called STCs. For systems that qualify, the value is usually applied in the quote as an upfront discount. Accredited installation is part of that eligibility.


Grid connection rules also matter in WA. From 1 May 2026, new or upgraded solar and battery systems on the southwest grid are subject to updated connection requirements. Systems over 30 kVA may need a different connection pathway. (Solar and Battery Requirements WA)


We’ll guide you through the current process and explain what applies to your site.

FAQs

  • What Size Solar System Do I Need?

    That depends on your energy use, roof space, and budget. For many homes, a 6.6kW system is a common starting point. Commercial systems vary a lot more and are usually sized around site usage and available roof area.

  • How Much Can I Save On My Energy Bills?

    Savings depend on the size of the system, how much energy you use during the day, your tariff, and how much power you export. We’ll give you a clearer estimate during quoting based on your property and usage.

  • Are There Government Rebates Available?

    Eligible solar systems can access STCs under the Small-scale Renewable Energy Scheme, which can reduce upfront cost. The exact value depends on system details and current program settings.

  • Do You Install Battery Storage?

    Yes. We can include battery storage in a new solar installation or discuss battery-ready options for future expansion. Battery incentives can depend on the current program and eligibility rules.

  • How Long Does Installation Take?

    Most residential solar installations are completed within a day. Commercial jobs can take longer depending on the size of the system and site requirements.
