Question

From the table: It shows the total area, sun hours per day and energy consumption of five different countries.

a. If a PV system of 270 Wp is installed in each of these locations, in which country would it be best to
place the panels to obtain the maximum output?

b. Now let us take a look at the United States. How much area, as a percentage of the total area of the US,
would be needed to cover the total annual energy demand of the country with solar panels having an
efficiency of 15%?

c. Which of the five countries would need to cover the lowest percentage of their area with solar panels to
supply all their electricity demand with solar energy?
