Australia’s Commercial Solar Market Continues to Surge
The Australian commercial solar sector experienced record-breaking growth in 2024, driven by strong demand in the 15-30kW and 1-5MW segments. According to the 2025 Annual SunWiz PV Market Report, the commercial and industrial (C&I) solar sector saw its best-performing year ever, highlighting the increasing reliance on solar for business cost reduction, sustainability goals, and energy independence.
Key Factors Driving Commercial Solar Growth
📈 15-30kW Installations Dominated the Market
- This segment was the fastest-growing, reflecting strong demand from small to medium-sized enterprises (SMEs) looking to reduce operational expenses and secure long-term energy price stability.
🏭 1-5MW Rollouts on the Rise
- Large commercial operations and industrial sites invested heavily in solar to reduce peak demand charges and improve energy self-sufficiency, especially noticable in corporate rollouts.
🔹 Declining Solar System Prices
- The falling cost of PV modules and BOS (Balance of System) components improved return on investment (ROI) for businesses.
🔹 STC and LGC Market Contributions
- The Small-Scale Technology Certificates (STC) and Large-Scale Generation Certificates (LGC) markets played a key role in subsidizing commercial installations, keeping investment costs competitive.
🔹 New Buildings
- Many new commercial buildings are putting solar up as soon as their roof is on!
