澳大利亚在屋顶太阳能部署方面处于全球领先地位，超过400万户家庭已安装了太阳能系统[1]，过去一年还新增了超过450,000个家庭电池[1]。然而，在公用事业规模太阳能建设上，澳大利亚却明显滞后，成为经济绿色转型的关键瓶颈。澳大利亚可再生能源机构（ARENA）正通过投资机器人、自动化和预制太阳能阵列等技术，力图实现低成本大规模部署[1]。
目前澳大利亚公用事业规模太阳能的安装成本仍比中国高出约1.5倍[1]，而国家电力市场中仅有约12吉瓦的公用事业规模太阳能接入[1]。ARENA制定了"30-30-30"目标，计划到2030年实现30%的效率和每瓦30美分的成本[1]。ARENA首席执行官达伦·米勒表示："向2050年前进，没有什么比在澳大利亚大规模制造的非常廉价的电力对澳大利亚经济优势更重要"[1]，他设想在澳大利亚偏远地区部署1,000吉瓦的太阳能[1]。这一战略旨在为绿色铁、氢能和关键矿物加工等新兴产业提供支撑[1]。
Australia has emerged as a global leader in rooftop solar adoption, with more than 4 million households installing residential systems [1], and over 450,000 home battery installations added in the past year [1]. However, this success in distributed solar has not translated to utility-scale development, creating a significant bottleneck for the nation's economic transformation [1].
Currently, Australia operates approximately 12 gigawatts of utility-scale solar capacity connected to the national electricity market [1]. Despite the lower costs of solar technology overall, utility-scale solar installations in Australia remain roughly 1.5 times more expensive than comparable projects in China [1]. To address this gap, the Australian Renewable Energy Agency (ARENA) is investing in robotics, automation, and prefabricated solar arrays to enable low-cost large-scale deployment [1].
ARENA has established the "30-30-30" target, aiming to achieve 30 percent efficiency at a cost of 30 cents per watt by 2030 [1]. According to ARENA CEO Darren Miller, "as we move towards 2050, nothing is more important to Australia's economic advantage than very cheap electricity manufactured at scale in Australia" [1]. Miller envisions deploying 1,000 gigawatts of solar capacity across remote regions of Australia [1], supporting emerging industries including green steel, hydrogen production, and critical mineral processing [1].
