we're in the UK so don't (yet) have the snow problem
just installed 4 kW of solar panels on the roof
the reason we're "limited" to 4 kW is that beyond that the electric company no longer regards you as a "micro-generator"
so you lose the feed in tariff
which is a bit odd, you'd think they'd want as much as possible fed in to the system
other little gem
"so Mr. Salesman, the other benefit will be that we still make electric if there's a power cut"
"ah" quoth he "no"
"er - why not?"
seems the electric company doesn't like all these houses sending electric back into the system after they've "isolated" a faulty bit of their network to repair it!
I feel a hack coming over me
wonder if a UPS would fool the inverter into thinking that there is still electric after a power cut, so it would keep generating power for the house
- and power the UPS of course!
(hmm is this the infinite energy loop thread all over again?!?)
