Slowdown in Rooftop Installations, Offset by Battery Growth

Solar’s Changing Story in 2025

For years, rooftop solar has been the hero of Australia’s clean energy boom. From suburban homes in Sydney to rural farms in WA, panels have been popping up faster than flat whites in a Melbourne laneway café.

But 2025 has thrown us a curveball: rooftop solar installations are slowing down. In July alone, only 205 MW of rooftop solar was added—one of the lowest monthly figures this year (PV Magazine Australia).

At first glance, that might sound like bad news. But here’s the twist: home battery installations are skyrocketing, with more than 19,500 batteries installed in July 2025 alone. That’s a record-breaking surge, showing Aussies are moving from “just generating power” to storing, controlling, and cashing in on it.

Why Are Rooftop Installs Slowing Down?

There’s no denying solar panels are still a smart investment—but the slowdown is driven by a mix of factors:

Market Saturation: Millions of Aussie homes already have rooftop solar—making us global leaders. The “early adopters” wave has passed, and growth is now slower.
Curtailment & Grid Challenges: In some regions, excess solar can’t always be exported to the grid, reducing returns for households.
Upfront Costs: Even though panel prices are cheaper than ever, installation costs (labour, compliance, etc.) remain a hurdle for some families.
Focus Shift: More households are now choosing to maximise existing solar systems with storage, rather than adding new panels.

Why Batteries Are Booming

The story flips when we talk about batteries. They’re the new Aussie energy must-have, and here’s why:

Energy Independence: Batteries let you store daytime solar and use it at night, slashing reliance on expensive grid power.
Bill Busters: Some households are even making a profit—like a Sydney family who earned a $487 credit from their battery exports (Daily Telegraph).
Virtual Power Plants (VPPs): Programs from retailers like AGL and Origin let you pool battery power with other homes, earning cash during peak demand.
Price Drops: Battery costs are falling, while government rebates and incentives are making them more affordable.
Resilience: In storm-prone regions, batteries mean your lights stay on when the grid goes down.

What This Means for Everyday Aussies

The rooftop solar slowdown isn’t the end of the story—it’s the beginning of a new chapter.

Here’s how it plays out:

Solar + Battery = Maximum ROI Households with both panels and batteries are saving more and exporting smarter.
Grid of the Future With more batteries in play, Australia is building a decentralised energy network, where homes become mini power stations.
Financial Freedom Beyond lower bills, solar + storage is helping Aussies pay off mortgages faster and build wealth in new ways.
