80% of power at 20 years is fairly standard for solar panels. It's a slow taper too, you just lose around 1% of output each year you sweat them.
There'll be other losses due to failures, damage etc. but it's not a situation where you should factor in a strict capital replacement cycle.
- ianai 9y agoYou should always factor in a capital cost (replacement, repair, etc).
- FooHentai 9y agoDoing it in the accounting manner that a typical firm would do is foolish in this instance. A homeowner is going to sweat assets, and in the case of Solar a 1% degradation per year means that, short of some damage or failure, the time you're likely to sweat them is between 20 and 80 years.
