Prices have in fact fallen by 2% in nominal terms in the past ten years, and have dropped by 30% in real terms, even though the cost of generating electricity has shot up.
事实上在过去的十年里，尽管发电成本上升了很多，但是西班牙电价表面上下降了2%，而实际上则下降了30%。
Boosting the conversion rate higher reduces the per-unit cost of generating the electricity, producing more power without requiring more space for the solar panels.
而如果电转化率提高，平均单位的发电成本就会随之降低，从而在不增加受光装置面积的情况下提高发电量。
The prerequisite of evaluating kinds of electricity generation technologies scientifically and fairly is to establish a unified conception, model and method of the generating cost accounting system.
科学与公平地评价各种电力生产方式的前提是建立统一的成本核算概念、模式和方法体系。
Careful consideration should be given to the scale of the electricity-generating technologies proposed to ensure that the lowest cost and risk pathways are identified.
要对提议中涉及的发电技术的范围加以仔细的考虑，以确保能够区分最低成本和风险路径。
