Medium-large name brand home panels can be had for under $1 per rated watt. So figure $0.20-0.25 per daily watt-hour, plus mounts, wiring, inverter, etc. My after tax rate for electricity is 0.14+, so it can pay off in the lifetime of the equipment now, the bare PV panel cost can be recovered in 4-5 years.

Electricity here is, IIRC, $0.055/kWH, so it would take nearly 3x
as long.  Hydro rules!  :-)
