What solar system works best for your building?

Multi-unit buildings across Victoria are embracing solar to cut energy costs, reduce emissions and build stronger communities—thanks to the Solar for Apartments program.

More than 160 multi-unit developments across Victoria have now installed, or are scheduled to install, solar systems through the Solar for Apartments program. Unlike free-standing homes, multi-unit developments can choose between two system types, direct-connected or solar sharing, depending on the building’s layout and ownership structure.

We visited two installations to see each system in action and hear from the retailers and residents about their experience.

Direct-connected system – Templestowe

Mark from Solahart says that direct-connected systems are ideal for buildings with varied ownership and energy needs. In Templestowe, residents installed Enphase microinverter systems across 27 lots, allowing each owner to choose a setup that suited their lifestyle and budget.

“With options ranging from two to four panels, it allows for tailored solutions, whether for larger families, retirees using more daytime energy, or landlords looking for a cost-effective way to offer solar to tenants,” Mark says.

This flexible approach made solar more accessible and fairer for everyone, especially in a building with different apartment sizes and usage patterns.

Pauline, a resident in the building, says installing solar was a smart decision as electricity prices continue to rise. The system also powers shared services like lifts and emergency lighting, helping reduce annual maintenance fees - as through the program a portion of energy can be supplied to a building’s common area (provided it doesn’t exceed the energy available to participating households).

“It makes me feel better knowing I’m using my own energy,” she says. “I’ve cut my bills by about a third and use the Enphase app to monitor usage and avoid overconsumption.” Pauline has become more aware of her energy habits and runs appliances like the dishwasher and washing machine in the morning when solar power is free.

She encourages other apartment residents to get on board “It will save you money. Prices will always go up but having solar means they won’t go up dramatically. Every building should do this—the world needs it.”

Solar sharing system – Fitzroy

Jono from Jusaso Group, the retailer behind the Fitzroy installation, says solar sharing systems are ideal for buildings with limited roof space and multiple lots.

“They enable residents to use more of the solar energy onsite rather than exporting it to the grid, which results in greater savings,” he explains.

Jono recommends involving committee representatives early in the process to ensure clear communication and smooth decision-making. His team helped navigate the complexities of retrofitting solar into a heritage-listed building, offering patient support and transparency throughout.

All owners contributed to cover the gap beyond the rebate, around $20,000 out of pocket, and felt confident in their investment.

Josh, a resident in the Fitzroy building, says the decision to install a 24kW solar sharing system was driven by rising energy costs and a desire to do something good for the planet. “It was a forward-thinking move that fostered a sense of collective responsibility,” he says.

Despite challenges with council approval and body corporate concerns, the group worked with their retailer and waited for an engineer’s report to confirm the roof’s integrity. The shared solar system now feeds into a central hub that distributes power fairly, cutting around 35 to 40% off energy bills and strengthening the building’s sense of community.

Josh recommends reviewing rebate eligibility, getting multiple quotes, and asking plenty of questions to make sure the system will fit your building’s needs.

After nearly a year of operation, Josh says the solar system has become “a shared asset that enhances our building’s value and liveability.”

The Solar for Apartments program is open until 30 April 2026. Rebates of up to $2,800 per household for residents living in eligible apartments, units and townhouses are available. If you’re thinking about solar now’s the time to start your application.
