What is "very high"? Much of the reason it takes so long to payback is labor, permitting costs, etc. If you reduce or remove those costs payback is in the order of 5 years at 10 cents/kwh.
People will point out that it's silly to factor out labor and permitting but those costs drop radically on grid scale 10MW+ systems where as they make up nearly 50% of the cost on a household scale system.
- vz8 6y agoVery high: for the hottest months of the year, power is $1100+/mo. Average for the last 24 months is just under $900/mo. It's a larger 1-story home: we've tried to address insulation, low-e glass, and AC SEER ratings. Working and teaching from home = consistent cooling demands throughout the day, every day.

- yaacov 6y agoIt’s just as insane in the US. 10x higher than average in Florida and 30x my small apartment in Washington state.
- shiftpgdn 6y agoYes, but what is your per kwh cost?
- yaacov 6y agoThat’s by far the highest residential power bill I’ve ever heard of anywhere. It’s 10x the Florida average!! Either you have a poorly insulated 25k sqft mansion or your neighbors are siphoning off your power for an indoor weed farm.

- SECProto 6y agoThe first thing I'd be considering there is air leak detection, followed by a ground source heat pump. Having a bill that high implies on the order of 9000 kWh used per month, which is crazy.
