Solar in the Adelaide Hills and Mount Barker

Yes. Westside works across all of South Australia, and our office is in Kent Town. We come to you for a 90-minute in-home consultation, audit your power bill and give you a detailed return on investment before you decide.

In the Hills we install solar, batteries, heat pump hot water, reverse cycle air conditioning, EV chargers, pool heat pumps and backup generators.

Solar is well established up here. The Clean Energy Regulator has recorded 6,592 small-scale solar systems in postcode 5251, which covers Mount Barker, and about 17,700 across ten Adelaide Hills postcodes from Stirling to Woodside, Lobethal and Hahndorf, to September 2026.

Batteries are catching up fast. Since the federal Cheaper Home Batteries discount began in July 2025, the regulator has recorded 1,025 home batteries in the Mount Barker postcode alone, and about 2,700 across those ten postcodes. If you already have panels, we look at whether a battery or an upgrade would pay at your place, starting from your power bill.

These are real Westside jobs. See the Mount Barker and Cherryville installs on our work page.

• Mount Barker: rooftop solar on a home with a green metal roof, with panels set out in several arrays around what was already on the roof
• Cherryville: rooftop solar on a tiled roof, with tall trees close to the house
• Hahndorf: a hybrid power system for Beerenberg Farm

The Hills get more weather than the plains. Bureau of Meteorology records show Mount Barker averages 762 mm of rain a year, against 547 mm at Adelaide’s Kent Town station, and its July nights average 4.7°C, against 7.6°C in Adelaide. At Lenswood the sun shines for 6.9 hours a day on average, against 7.6 in Adelaide, and only 3.9 hours in June.

So we size solar for your winter, not just your summer, and check how a battery will charge on short, cloudy days. Cold nights also make heating a big part of the bill, which shapes the right reverse cycle air conditioning and heat pump hot water for your home.

Those two homes show why we design on site. A roof with existing fixtures may need panels split across several arrays. A roof near tall trees needs a close look at shade, orientation and where the panels will actually produce. We check all of this at your place.

The Hills know what a bad fire day means. The Cudlee Creek fire, which started on 20 December 2019, burned 23,000 hectares and destroyed 84 homes. 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 the power on matters to you, tell us at the start. Not every battery provides backup by default, so it has to be designed in. Some systems run essential circuits, and larger ones can back up the whole home.

For long outages, or for a farm or business with heavy loads, a backup generator may suit better, on its own or alongside a battery. We will set out both options for your property.

Mount Barker District passed 45,000 residents in 2024 and forecasts about 63,300. Many of those homes are still to be built.

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.
