How many homes can be powered by 1 megawatt of solar energy?

The current national average of homes powered by a MW of solar photovoltaics is 164.

However, the average number of homes powered per MW of PV varies from state to state due to a number of factors including:

  • average sunshine (also called insolation)
  • average household electricity consumption
  • temperature and wind

The average number of homes powered per megawatt of PV for a given state is simply the quotient of the average PV system performance estimate and the average annual household consumption. Learn more about how we calculate this number.
