从2000年到2016年，太阳能光伏的部署以年均44%的复合速度增长，从0.8吉瓦(GW)增长到291吉瓦。太阳能光伏组件的“学习率”很高，在18%到22%之间，这取决于所分析的时间段。随着部署的快速增长，从2009年底到2016年，模块价格下降了80-85%。2010年至2016年，全球公用事业规模的太阳能光伏项目的加权平均总安装成本和平均电价(LCOE)分别下降了65%和67%。

Solar PV deployment has grown at an annual average compound rate of 44% between 2000 and 2016, from 0.8 gigawatts (GW) to 291 GW. Solar PV modules have high “learning rates” of between 18% and 22% depending on the period analysed. With the rapid growth in deployment, module prices have declined by around 80–85% between the end of 2009 and 2016. Between 2010 and 2016, the global weighted average total installed cost and the levelised cost of electricity (LCOE) of utility-scale solar PV projects fell by 65% and 67% respectively.
