有谁装了太阳能板?觉得怎样?

As of January 2017, the average cost of solar in the U.S. is $3.26 per watt ($32,600 for a 10 kilowatt system). That means that the total cost for a 10kW solar system would be $22,820 after the 30% Federal ITC discount (not factoring in any additional state rebates or incentives).
How long will my photovoltaic system last? Because solar systems have no moving parts, they very reliable and require little maintenance. Solar modules come with a manufacturer's warranty for a lifecycle of between 20 and 25 years. Depending on the quality, the installation can last up to 30 years.


如果10KW投资是$32600(不算折扣),一年发电14400度(不考虑冬天),每度电收入$0.20,一年回报$2880.
按25年使用寿命算,全部收入为$72000。投入的本金全部损耗。

看起来不是太好的投资。
 
最后编辑:
前几天CBC有个报道:东部某省(记不清了)有个人建了个全GREEN ENERGY的房子。每年供给电网的多余从电网输入的电。所以他不用交电费。但是,当他从电网输入电时,他还要交HST,这令他很不爽。
 
I once thought about it, until I read a post about someone had to clean his roof panels in winter after every big snowfall.:evil:

卖给安省政府 $0.80/度。

很多事情,不需要努力去研究,随波逐流就是了。

这东西,你看小区有三分之一的屋顶装了,你再考虑也不迟。
