> As I mentioned in a peer comment I'm more interested in tropical | equatorial performance Perhaps you should qualify your statements, because this: > Currently panels drop to 80% efficacy after 10 years and are doorstops in 20 This is an unqualified factual statement and is simply not true. > Your average degradation figures are the figures from big meta studies The big meta studies do show that degradation is a bit faster in higher temp environments for some kinds of panels. There is however zero evidence that solar panels will be "door stops in 20".

> There is however zero evidence that solar panels will be "door stops in 20". If you're building a large area solar farm to ship power to Singapore would you keep a panel after 20 years or door stop it? What if the peak power output for particular climatic conditions comes from lesser used cheaper PV types that degrade faster than common ones at temperate latitudes? The people studying this are coming at this with mindset of those that move 800 million tonne of iron ore per annum. My original comment was framed to indicate the interest was hyper efficient at scale deployment in specific environments .. not running a beer fridge in Melbourne.

If that was your intent, you should go reread it to see why everyone else sees you making a clearly false claim that does not contribute to the discussion. > If you're building a large area solar farm to ship power to Singapore would you keep a panel after 20 years or door stop it? That's gonna depend on land value, non-panel infrastructure costs and replacement costs. If replacement costs are high then and land value and other infrastructure costs are low, then solar farms will be expanded and replacement will be delayed. If the opposite then you'll see existing panels replaced sooner. I do expect that in a couple of decades we will see solar panel reconditioning and recycling becoming increasingly important.
