    The alternative to using an RTG is to use a solar panel.
    A typical solar panel installation on a house roof in the UK provides about
    1000 kW h of electricity each year.
    Calculate the average electrical power output of the installation.

    The maximum intensity of the sunlight on the surface of Mars at its equator is
    similar to that in the UK.
    Estimate, using your answer to Question 4.5, the area of the solar panel needed
    to provide an average power output of 100 W on Mars. Give your answer to an
    appropriate order of magnitude.

    kWh is a unit of energy equal to 3.6MJ http://www.gcse.com/energy/kWh2.htm

    so calculate the number of Joules in 1000 kWh and divide by the number of seconds in 1 year to get the average power generation over a year.
