Rooftop solar

We’re seeing massive growth in the number of customers installing rooftop solar photovoltaic (PV) systems – more than 100,000 homes in our network have connected rooftop solar. It’s a popular way of taking control of energy reliability and costs in your home, and there are some great incentives available through the Victoria Solar Homes Program.

Our network takes electricity to and from your home. This means we need to balance the amount of power flowing from large-scale generators and private solar PV systems to keep the electricity supplies reliable for all our customers.

On days when you generate more solar electricity than your home needs for your home, you may be able to export this excess power back to our network and receive money in the form of a feed-in tariff.

In many areas, the ability of the network to absorb the solar PV exports can be limited. It doesn’t stop anyone from installing a solar PV system, but it can impact the amount of exports available.

We’re here to help by giving you access to everything you need to know about investing in solar PV, all in one place. Here you’ll find information on:

  • Getting the right smart inverter for your needs.
  • Ensuring you’re on the right energy plan and tariff to minimise your electricity costs.
  • Finding an accredited installer or solar retailer.
  • All the things to financially consider for your solar PV investment.

We’re proud members of the Clean Energy Council who represent and work with Australia’s leading renewable energy and energy storage businesses and rooftop solar installers. They have a range of information available for consumers about buying solar, including handy guides and tools to find a solar retailer or installer in your area.

Other helpful information is available through government, industry and consumer bodies that have tools and tips for you to make sure you make the right electricity choices for your home:

Your 5 steps to solar success

  • 01
    Check before you connect

    We want to help you to export the amount of excess solar you’re looking for. However, this may not be possible depending on the capacity of the network in your neighbourhood. This won’t stop you from installing solar for your own consumption. But it might make a difference to the size of the system you contract.

    Your installer will need to fill out this form and there are further relevant documents at the bottom of the page.

    Please make sure your installer provides us with your contact details on the application form too. That way, we can keep you both informed of the outcome of the assessment.

    Choose an accredited installer

    Installers and solar retailers are accredited by the Clean Energy Council to bring about a better standard of service within the solar and storage industry. Click here to download our factsheet and learn more about installation.

    Check your settings

    Make sure you have the right inverter with the right settings. This is something you need to make sure your installer does. All inverters installed within the United Energy network will require ‘Australia A’ settings for protection and response modes.

    A smart inverter has power quality response mode settings, like ‘Volt-Watt’ and ‘Volt-Var’. That means it makes sure your system doesn’t trip off when the power voltage fluctuates. Otherwise, when trips happen, your system will no longer generate power for your home or for export.

    It’s essential to ensure your installer specifies the need for a smart inverter and that your installer confirms the settings have been applied and turned on when the system is connected.

    If you'd like more information on which settings to have applied, take a look at the Model Standing Offer document.

  • 04
    Review your contract

    Your installer will submit a contract with us on your behalf, letting us know your system is installed and has the right smart inverter settings working. This contract is known as a ‘Model Standing Offer’ and will register your solar connection with us.

    If we don’t know you’re connected, you won’t be able to receive the feed-in tariffs you may be expecting, and we won’t be able to tell if there are issues with your connection.

  • 05
    Maintain your solar panels

    Once your system has been installed, there are two main things you’ll need to do each year to maintain your solar panels and make sure they are working efficiently.

    The first is to keep them clean. You should remove any build-up of dirt and grime. The second is to make sure you follow the regular maintenance schedule that your installer will provide. This will ensure your system is operating correctly and safely.
