It's higher than retail rooftop PV costs which is $450 per kwp. Which country is that in? I don't know of any country where you can get e.g. a 5 kilowatt rooftop system installed for $2250 (except perhaps with special government tax credits/incentives). The costs for this Chinese project include not just the PV modules but the land, racking, inverters, transformers, grid connection, and installation labor.
