Problema Solution
One square metre of solar panel produces about 100 kWh of electricity per year.
One MWh is 1 000 kWh.
Approximately how many MWh of electricity would 20 square metres of panels produce in one year?
Answer provided by our tutors
1 MWh = 1 000 kWh divide both sides by 10
1/10 MWh = 100 kWh
Let 'x' represent the number of MWh that 20 m^2 produce in 1 year.
Assuming the electricity produced is directly proportional with the area we can write:
1 : (1/10) = 20 : x

........
x = 2 MWh
20 m^2 of panels will produce 2 MWh electricity.
