Installing and connecting solar panels and battery systems

Looking to install a solar PV or solar battery system? We recommend you follow these tips to find the right solution.

Do your research

The following pages provide information on what to look out for when installing solar PV and battery systems.

Solar and battery costs

Installing a solar PV or battery system may require an upfront investment. The larger systems usually cost more. The Commonwealth Government's Small-scale Renewable Energy Scheme can help reduce these upfront costs for solar PV.

Some commercial businesses also allow customers to lease solar PV and battery systems or to purchase them on finance.

Generally, purchasing the system outright will be more cost effective, so do some research to find out the best way to pay for your solar PV.

Here are some resources to get you started:

Shop around for an accredited installer

Get a range of quotes from different solar and battery installers. You’ll find a list of accredited installers on the Clean Energy Council's website.

Ask for a written quotation and contract before signing up. Understand the following:

  • the total price of the system and installation
  • proposed start and completion dates
  • specifications of the size and output of the system as well as the inverter specifications
  • estimates of the average output of the system, including an estimate of output during the best and worst months of the year
  • warranties and guarantees.

If you have any problems with your solar installer you can contact NSW Fair Trading on 13 32 20.

In most circumstances, your solar installer will manage your connection to the grid.

You can also get more information about connecting your solar PV system to the electricity network from your electricity distributor, which will be Ausgrid, Endeavour Energy or Essential Energy.  Take a look at your most recent bill to check the name of your distributor.

Frequently asked questions

How can solar generation reduce my electricity bills?

Instead of purchasing all your electricity from your retailer, you can use the energy you generate from your own solar system and only purchase extra electricity if you need it.

How much can I expect to save on my electricity bill with a solar PV system?

That depends on a range of factors, including the size, quality and site of your system, how you use electricity, the weather and any feed-in tariff paid by your retailer.

Your installer can advise you on the expected output of a particular model and size of system. If you have a typical electricity account on hand and you know the time of day you typically use your electricity it will help your installer match the system to your needs.

How much does a solar PV system cost?

There are a range of prices for different PV systems. You should seek independent advice on the actual costs of a system.
