### English
* **Current Status:** Australia's residential solar market is thriving with 22 GW installed, while the Commercial and Industrial (C&I) sector lags significantly behind at only 5.6 GW.
* **Growth Stagnation:** Annual C&I solar installations have plateaued at approximately 600 MW, compared to 2,500 MW in the residential sector.
* **Future Potential:** Technical potential for C&I rooftop solar is estimated at 40 GW, potentially exceeding 80 GW by 2050 if agricultural areas are included.
* **Core Barriers:** 
    * Distorted investment frameworks (projects are often caught between residential and utility-scale incentive thresholds).
    * Complex, inconsistent network tariff structures.
    * Fragmented and unpredictable grid connection processes.
    * An uneven playing field for network services.
* **Proposed Solutions:** The IEEFA recommends standardizing network tariffs, streamlining grid connections, and reviewing economic regulations to allow distributed energy resources to compete with traditional infrastructure.

### 中文
* **现状：** 澳大利亚住宅屋顶太阳能装机量已达 22 GW，而商业与工业 (C&I) 部门的装机量仅为 5.6 GW，明显滞后。
* **增长停滞：** 商业与工业太阳能的年度装机量徘徊在 600 MW 左右，远低于住宅领域的 2,500 MW。
* **未来潜力：** 预计到 2050 年，商业与工业屋顶太阳能的装机潜力可达 40 GW；若计入农业用地，潜力可超过 80 GW。
* **主要障碍：** 
    * 投资框架存在偏差（项目往往处于住宅激励政策与公用事业级激励政策之间的“地带”）。
    * 电网关税结构复杂且不统一。
    * 电网并网流程碎片化且难以预测。
    * 电网服务缺乏公平竞争环境。
* **建议方案：** IEEFA 建议标准化电网关税、简化并网流程，并审查配电网经济监管政策，推动分布式能源与传统基础设施进行竞争。
