"hundreds of dollars per square meter" not true anymore.

104.08 EUR tax (20%) included for 410Wp gives 0.254 EUR/Wp
1722 x 1134 x 30 mm = 1.92 square meter gives 53.38 EUR/m2.
Some wooden floor are more expensive than PV per square meter.
People forget that PV, battey, wind costs are still decreasing.
- esperent 3y agoA quick calculation on Wolfram Alpha: to cover 2% of the world's surface at 50EUR/m2 would cost roughly 540 trillion euros, or 5.5 years of current world GDP.

And the decrease has been exponential, with no reason to believe it will stop at the next order of magnitude. Anyway, covering 2% of the world with anything is a huge undertaking.
- guerby 3y agoIf I'm not mistaken 510 millions square kilometer earth surface, 2% of that 10 millions square kilometer, at 200 Wp/m2 gives 2 PW peak. Current peak electricity production capacity is about 7.5 TW according to: https://www.statista.com/statistics/267358/world-installed-power-capacity/ https://www.statista.com/statistics/267358/world-installed-p...
