2675 kWh system (about 3/4 of the yearly use of a regular family in the Netherlands) costs 6379 euros (9346 USD as of now) + 1498 euros (2194 USD) for installation. The system is sold as 'DIY' though so it should be possible to install it yourself.
Where I live there is a 1500 euro subsidy for the installation, putting the payback time (assuming constant energy costs) at around 7 years; with opportunity costs accounted at deposit account rates around 11.
I haven't decided yet but I think it's already an OK investment (not great but OK), mostly because of the subsidy; without that it would require significant increases in energy costs over the next couple of years to make it attractive.
