本文探讨了英国（UK）的光伏（PV）行业的经验，并考虑了当前的标准，模块效率和未来的环境趋势。政府就太阳能光伏发电关税的全面审查进行咨询，建议将英国光伏发电装置的发电关税降低50%以上。自2010年4月引入上网电价计划（fit）以来，小规模光伏技术的部署迅速增加。FIT政策的核心原则是在固定期限内提供有保证的价格，以使更多的投资者能够投资。对英国康沃尔的两个实际装置进行了财务分析，以确定拟议的FIT削减将对4千瓦以下的典型家用光伏系统产生的影响。结果表明，健康的投资回报率（ROI）仍然可以实现，但未来的安装应侧重于抵消国家电网所需的电力，作为真正可持续发展的长期推动力，而不是补贴计划。未来安装的盈利能力必须在服务期间和服务结束时考虑，如上网电价、模块效率和与寿命结束处置相关的成本影响。(C) 2012 Elsevier Ltd.版权所有。
This paper explores the photovoltaic (PV) industry in the United Kingdom (UK) as experienced by those who are working with it directly and with consideration of current standards, module efficiencies and future environmental trends. The government's consultation on the comprehensive review for solar PV tariffs, proposes a reduction of the generation tariff for PV installations in the UK of more than 50%. The introduction of the Feed-In Tariffs scheme (FITs) has rapidly increased deployment of PV technologies at small scale since its introduction in April 2010. The central principle of FIT policies is to offer guaranteed prices for fixed periods to enable greater number of investors. A financial analysis was performed on two real-life installations in Cornwall, UK to determine the impact of proposed cuts to the FIT will make to a typical domestic PV system under 4 kW. The results show that a healthy Return on Investment (ROI) can still be made but that future installations should focus on off-setting electricity required from the national grid as a long term push for true sustainability rather than subsidised schemes. The profitability of future installations will have to be featured within in-service and end-of-service considerations such as the feed-in tariff, module efficiencies and the implications of costs associated with end-of-life disposal.
