Reply to comment by Tomcatjones in Record efficiency of 26.81% for large silicon solar cells by Wagamaga

There's a greater difference than that. Not that it matters that much, as we have quite a lot of dessert and wasteland globally.

A 2.5 GW solar plant would in reality average between 0.25 and 0.5 GW due to limited capacity factor. A nuclear power plant usually also use multiple reactors, with only limited increase in size.

A power plant can’t be built on rooftops. Rooftops also have less inefficiency from grid transmissions. HEMS however have lower efficiency when battery power is used. Nuclear power plants are open to attacks. So is the software of inverters. It’s a messy calculation, but below the line to me the decentralized solution, with solar energy generated close to where it’s used and excesses stored in EVs is the winning combo.
