What are kWh or Kilowatt-Hours?

kWh or KiloWatt-Hours

If you leave a 60 Watt light bulb on for one hour then this uses 60 Wh (or Watt-Hours) of energy.  Most solar electric systems are considerably larger and so are measured in Kilowatts (1,000 Watts) and Kilowatt-Hours (1,000 Watt-Hours or kWh).
