Netherlands. No distribution fees are separate.

Roughly speaking the electricity is about €0.06 with about €0.20 in taxes on top. So offsetting consumption nets me about €0.26 cents per kWh.

The installation of a 2800kWp system cost me about €2600 and generates between 2400-2750kWh annually, so about €650 euro. In a 10 year timespan that’s an IRR of 20%, creeping up to 25% for 20 years.

Thanks for the numbers! I had no idea taxes were such a large fraction elsewhere. Good to know/consider. I'm most familiar with California. (and actually can't give a % that is taxes offhand)

After the first year of having PV, I determined my own payoff time of about 5-7 years, so that was nice and self-justifying, and haven't dug deeper into details on that.

2800kWp => 2800Wp :)
