Over last several years the cost to install 1kW was, ehm, less than €200 if you do it the retail way - 2..4 500W panels from the warehouse next street and a microinverter. Thanks, China. In addition to my primary system, I have a toy installation with 6 500W panels and a micro. I paid around 500 euros for that last August and by this time this toy installation generated me 1281 kWh. That's around €400 in terms of retail energy prices. So, I'll break even this August. So, everything generated after would be exactly the "money saved".
