Why Solar Investments in 2025 Are Falling—And How to Jumpstart Growth

The Big Solar Question: Why the Dip in 2025?

Australia’s clean energy story has been a roaring success for years. From rooftops in Brisbane to farms in WA, solar has been shining bright. But here’s the curveball: in the first half of 2025, investment in large-scale solar and wind projects plummeted by 64%—dropping to just USD $363 million, down from a hefty $1.6 billion the year before (PV Magazine)

That’s not just a blip—it’s a wake-up call. If we’re aiming for 82% renewables by 2030, we can’t afford to lose momentum. So, what’s really going on—and how can we fix it?

What’s Behind the Slowdown?

A few speed bumps are holding back solar investments in 2025:

Grid Congestion: Too much solar is generated in certain regions, but our grid struggles to handle it. That leads to “curtailment”—when solar farms are forced to dial down output..

Policy Delays: While the Capacity Investment Scheme (CIS) is a positive step, planning approvals and grid connection processes are often painfully slow. Investor Caution: Rising interest rates and global uncertainty have some developers pressing pause on big projects.

Land & Community Challenges: Large solar farms face pushback around land use, biodiversity, and rural community acceptance. In short: the tech is ready, Aussies want clean power, but red tape and roadblocks are stalling the pace.

Bright Spots in a Cloudy Year

It’s not all doom and gloom. Rooftop solar and home batteries are absolutely booming. In fact, 74,582 Aussie homes added batteries in 2024—up 62% year-on-yearPV Magazine Australia)

Even better, many households are joining Virtual Power Plants (VPPs), turning their excess solar into extra income. Some Aussies are even using solar + battery savings to pay off their mortgages faster (Daily Telegraph)

So while the big end of town slows down, Aussie households are quietly keeping the solar revolution alive.

How Do We Jumpstart Growth?

At NexaPower, we believe the solution is a mix of smarter policy, stronger investment, and everyday Aussies leading the charge. Here’s what can get us back on track:

⚡ Supercharge the Grid

🌞 Back Aussie Manufacturing

Projects like the Stellar PV plant in Townsville (set to build 2 GW of solar wafers right here at home) show we can boost supply chains, create jobs, and cut reliance on imports (Courier Mail)

💰 Smarter Incentives

Keep supporting households with rebates for solar and batteries.

Expand Virtual Power Plant (VPP) rewards, so more homes earn by sharing power with the grid.

🌱 Community Power Matters

Bring rural communities along for the ride with local benefit schemes, job creation, and fairer land deals. Highlight success stories where solar farms coexist with farming—“sheep under panels” is a win-win.
