You're bang on Fotze. I've run some crude numbers but they are in a log book at home. It's still on the edge of feasibility, depending on the amount of value one puts into "greenness".
I completely forgot to mention escalating electricity prices, great call. Inflation alone makes it relatively worth more and more every year. As for maintenance, there will certainly be some, but the whole system is solid state (no moving parts), so friction is not a problem (the major cause of most things breaking down).
