We are going to build a PV system on a roof of 10m2, and we have two possible PV modules:

(1) A first generation module with efficiency η=18% and cost of 0.80€/Wp.

(2) A second generation PV module with efficiency η=10% and cost of 0.40€/Wp.

The non-modular costs are 100€/m2.

Note that the irradiance under standard test conditions is 1000W/m2.

What is the cost in € of implementing a PV system for the entire roof using first generation technologies?
