A typical all-electric home (heat pump + induction + EV charging) consumes 15,000 to 22,000 kWh per year — roughly double the average US household. A 7 kW residential solar array generates 9,000 to 11,000 kWh per year in most US climate zones, covering roughly half the all-electric load. Stacked IRA credits reduce the all-electric retrofit payback to 7 to 10 years.
Full system cost stack
Heat pump (cold-climate, installed): $12,000. Heat-pump water heater: $3,200. Induction cooktop: $3,000. EV charger Level 2: $1,500. 7 kW solar: $19,000.
Total: $38,700 before incentives. IRA 25C heat pump $2,000 + induction $840 + EV charger $1,000 + 25D solar 30 percent ITC $5,700 = $9,540 in credits. Net $29,160.
Annual operating cost comparison
Conventional home (gas furnace + ICE car): $3,200 to $4,200 annual energy spend (gas + gasoline + electric).
All-electric home with 7 kW solar: $1,400 to $1,800 annual electric spend, zero gas, electric vehicle charging mostly covered by solar export credits.
