Solar in Gawler and the Barossa

Yes. Westside works across all of South Australia, including Gawler and the Barossa. You deal with us directly, from the first call to installation. Our office is in Kent Town and our number is 08 8451 2120.

We hold SA electrical contractor licence 353970, and we are South Australian owned and operated.

Solar is well established in this region. The Clean Energy Regulator has recorded 6,140 small-scale solar systems in postcode 5118, which covers Gawler, and about 7,970 across the main Barossa postcodes of Lyndoch and Williamstown (5351), Tanunda (5352), Angaston (5353) and Nuriootpa (5355), to September 2026.

Batteries are the newer step. Since the federal Cheaper Home Batteries discount began in July 2025, the regulator has recorded 817 home batteries in 5118 and 1,011 across those four Barossa postcodes. If you already have panels, the useful question is often what to add, and whether a battery would pay at your place. We work that out from your power bill.

The Barossa runs colder than Adelaide in winter. Bureau of Meteorology records show July nights at Nuriootpa average 4.7°C, against 7.6°C at Adelaide’s Kent Town station. Summer days are just as hot, with January averaging 30.3°C at Nuriootpa.

That means heating as well as cooling shapes your bill. We size reverse cycle air conditioning for both, and check how a heat pump hot water system will perform on cold mornings before we recommend one.

Parts of the Barossa and the hills around Gawler are bushfire prone. SA Power Networks says that when fire danger is extreme it may need to switch off power to protect lives and property, and it advises people in bushfire-prone areas to plan for losing power and consider a generator or battery backup.

If keeping essentials running matters to you, tell us at the start. Backup has to be designed in, because not every battery provides it by default. For longer outages, or for a farm with pumps and heavy loads, we also install backup generators.

Gawler is one of South Australia’s growth areas. The State Government has rezoned land for about 350 new homes at Gawler Belt and is planning for more than 10,000 new homes at Concordia.

If you are building, it is cheaper to plan solar, a battery and an all-electric home before the walls go up than to retrofit later. Bring your plans to the consultation.

We work on homes first, as well as farms and businesses. Most people start with one problem, such as a high bill or an old hot water system, and we look at how it fits with the rest of the home. Start with our solar and battery pages if you want the detail.

• Solar panels, new or upgraded
• Solar batteries, including adding to existing solar
• Heat pump hot water
• Reverse cycle air conditioning
• EV chargers, pool heat pumps and backup generators

Send your details or call us, and we will arrange a time. A member of the team comes to your home for about 90 minutes. We audit your actual power bill, look at your roof and your usage, and work out what each option would do for your household.

You get a detailed return on investment before you decide. If something is not worth doing at your place, we will say so.

The more we can see, the better the advice. Have a recent power bill ready, and a gas bill if you have one. If you already have solar, tell us the system’s age and whether you have thought about a battery.

If you run a farm or business, tell us when your main loads run. That shapes whether commercial solar, storage or a generator makes sense.
