A 410W solar panel at 29€? I really doubt that honestly. Cheaper than plywood.

[DaoVeles]

This is not shade on the original comment. But I do find it funny when economists that extrapolate out to infinity.

Comely divorced from the real world materials and ecology.

Efficiency going up is one way to reduce instillation costs which grid scale solar really cares about.

470W + even cheaper inverters seems likely.

Thin-film solar panels will be much cheaper than that. They will be printed in huge quantities.

Economies of scale baby. Another 10x more in production another 30% less in price.

>Economies of scale baby.

That's what they said about regular electric grid power too - that it "soon" would be so cheap as to be unmetered. That was half a century ago and it didn't pan out...

The reasons for this are entirely political. Technology, left to its own devices, would have followed the usual maturity curve on fission power, which would be universal, ubiquitous, abundant, and cheap.

Solar power has neither the geopolitical problems nor the squishy 'environmentalist' ick factor of fission. There's no reason not to expect another halving or two of PPP dollar per Watt to follow.
