Abstract This paper presents geographic maps of the profitability of PV and CPV solar projects over 1,960,000 km2. Such maps supplement the irradiance maps used in solar project planning and are relevant to government policy makers to assess the impact of incentives on profitability. Also, they are useful to solar project developers to identify geographical areas in which a required rate of financial return can be expected. Eight such maps of central Canada are presented in this paper and show the impact on profitability of different levels of government incentives, the difference in profitability between PV and CPV and the impact on profitability of delaying a project start date from 2016 to 2020. Government incentives of 10%–30% of the capital cost improve the internal rate of return (IRR) by between 0.7 and 4.67. For PV, the orientation of the modules is optimized to achieve maximum IRR resulting in an IRR increase of between 1.3% and 8.2%. Since CPV is a more recent technology than PV, its capital costs are projected to decline faster and we quantify the impact on IRR by showing that CPV has a higher IRR than PV of between 0.55 in 2016 and 3.6 in 2020.

政府激励对太阳能经济可行性影响的地理地图

摘要 本文介绍了超过 1,960,000 平方公里的 PV 和 CPV 太阳能项目盈利能力的地理地图。此类地图补充了太阳能项目规划中使用的辐照度地图，并与政府决策者评估激励措施对盈利能力的影响有关。此外，它们对于太阳能项目开发商确定可以预期所需财务回报率的地理区域很有用。本文展示了加拿大中部的八幅此类地图，显示了不同级别的政府激励措施对盈利能力的影响、PV 和 CPV 之间的盈利能力差异以及将项目开工日期推迟到 2016 年至 2020 年对盈利能力的影响。 政府激励措施资本成本的 10%–30% 将内部收益率 (IRR) 提高 0.7 到 4.67。对于光伏，优化模块的方向以实现最大 IRR，从而使 IRR 增加 1.3% 至 8.2%。由于 CPV 是比 PV 更新的技术，因此预计其资本成本下降得更快，我们通过显示 CPV 的 IRR 高于 PV 的 IRR 在 2016 年的 0.55 和 2020 年的 3.6 之间来量化对 IRR 的影响。
