Feed-in-Tariff (FiT) mechanisms have been important in boosting renewable energy, by providing a long-term guaranteed subsidy of the kWh-price, thus mitigating investment risks and enhancing the contribution of sustainable electricity. By ongoing PV development, the contribution of solar power increases exponentially. Within this significant potential, it is important for investors, operators, and scientists alike to provide answers to different questions related to subsidies, PV efficiencies and costs. The present paper therefore (i) briefly reviews the mechanisms, advantages, and evolution of FiT; (ii) describes the developments of PV, (iii) applies a comprehensive literature-based model for the solar irradiation to predict the PV solar energy potential in some target European countries, whilst comparing output predictions with the monthly measured electricity generation of a 57 m² photovoltaic system (Belgium); and finally (iv) predicts the levelized cost of energy (LCOE) in terms of investment and efficiency, providing LCOE values between 0.149 and 0.313 €/kWh, as function of the overall process efficiency and cost. The findings clearly demonstrate the potential of PV energy in Europe, where FiT can be considerably reduced or even be eliminated in the near future.
上网电价（FiT）机制通过提供长期保证的每千瓦时电价补贴，在促进可再生能源发展方面发挥了重要作用，从而降低了投资风险并提高了可持续电力的贡献。随着光伏（PV）的不断发展，太阳能的贡献呈指数级增长。在这一巨大潜力下，对于投资者、运营商和科学家来说，回答与补贴、光伏效率和成本相关的不同问题非常重要。因此，本文（i）简要回顾了上网电价的机制、优势和演变；（ii）描述了光伏的发展；（iii）应用基于文献的综合模型来预测一些目标欧洲国家的光伏太阳能潜力，同时将输出预测与一个57平方米光伏系统（比利时）的月实测发电量进行比较；最后（iv）根据投资和效率预测平准化能源成本（LCOE），得出LCOE值在0.149至0.313欧元/千瓦时之间，该值是整个过程效率和成本的函数。研究结果清楚地表明了欧洲光伏能源的潜力，在欧洲，上网电价在不久的将来可能会大幅降低甚至取消。
