I paid €3900 for 22 panels, 7.2kw system here in the Netherlands. I did install it myself (but the whole package was delivered and the electric connections done by the supplier), and the panels and inverter are cheap Chinese brands. As I didn't situate them ideally and they lose efficiency as the heat up quite drastically I expect to generate between 4500 and 5000kwh. That should save me about €800 a year so this is a pretty solid business case. So to me the US prices seem even more ridiculous
