Their project life for solar and wind both seem to be 20 years to calculate LCOE.

That seems to be correct for wind that needs major refitting, but solar seems to be more durable.

Google suggests 10% loss after 20 years for solar.

Therefore, i have doubts that presented numbers are accurate. Solar will simply churn along for far longer, while wind will have to becreplaced.

Not disputing, but where do you see this?

We don’t have good numbers for the longevity of wind turbines either, though it’s probably under 25 years [1].

Unlikely. The terminal value of that residual at any reasonable cost of capital is, while non-negligible, not going to be significant. (See Slide 6 for how each source’s LCOE reacts to rates.)

It was from slide 17, project lifetime (it was for combined with storage).

I looked more closely and it's actually 30 years (25 for residential) for solar, slide 37 (Key assumptions)- facility life row.

For wind, it assumes 20 years.
