Nice. In the US, it cost us $35k to install 7.6 kW panels + 13 kWh battery. But our PG&E electricity prices in the Bay Area are also several times more expensive than in Europe ($0.50 per kWh) so it will also pay off in 8-10 years.

$35k and $0.50 per kWh is quite pricy. My brother is in US (Kansas) and he told me that for the time being, it doesn't make sense for him to get solar, as the utility price is something like $0.07/kWh and he uses a low amount of electricity and install cost would be somewhere around $20k-25k. I think the math works?

We also did the math for ourselves with 8-10 years at current electricity prices: 30 eurocents/kWh (which got 3x more expensive in the last 10 years). So we might be lucky and break even even sooner.

Plus $15k to move them for new shingles when the time comes, if they’re on shingles.

I wonder why we don’t use them to build shade structures instead.

Curious, when you calculate 8-10yr payoff, are you taking into account the last 10-20 year kwh cost inflation trend as well?

!35K, I just payed $11K for the same in Europe. But here in Spain it is not financially worth it, but insurers against frequent brownouts and 3 outages a year
