摘要
中国光伏电站的上网电价按区域不同分为3类,因此太阳能资源丰富地区的光伏项目收益不一定较好。通过建立"资源-发电量"模型和财务分析模型,在不同电价区内,建立起资源与收益的直接相关性,并对结果进行分析,得出结论:Ⅰ类电价区项目收益最好,是投资者首选;除小部分资源较好的区域外,Ⅲ类电价区大部分项目需要额外补贴才能盈利;太阳能资源相同时,电价差异会使项目内部收益率变化0.9%左右;相邻电价区内的项目要获得相同收益时,峰值小时数相差100~120 h。
Because of generation prices of photovohaie power are in three classes in different areas in China, earnings of statinns buih in the areas, where may be of rich in solar power, are not always great. By establishing the ＂＇resource-electricity output＂ model and the financial analysis model, this paper set up a direct relationship between the resource and IRR in dift^rent tariff zones. The ,＇esl,lts were analyzed and the following conclusions were obtained： the projects in tariff zone of class [ will win the best benefits and will be the first choice for investors： apart from a small portion of projects with solar resource in better class, most of the projects in tariff zone of class in can obtain a reasonable return on investments only when they gain extra subsidies. The IRR of the projects with the same resources will change by around 0.9% in different tariff zones; the IRR of the projects in the neighboring tariff zones will be the same when the peak hour change about 100-120 h.
