It totally makes sense because you always compare price of installation against a certain installed capacity in TW.

I was not speaking of the efficiency of transforming 20% of the sun energy into electricity.

So what that 20% means in case of solar? Utilisation factor also doesn’t make sense - what matters is how many GWh you van get per dollar of installation, but you don’t measure this in %.
