how much solar energy is received by 5m square in 2 hours? given solar constant is 1.4kW per m square
[power = energy x time]
From the solar constant we deduce that
1.4 kW of power is incident upon every m2 of area
so,
total incident power every 5 m2 of area will be = 1.4 kW x 5 m2 = 7 kW
now,
the total energy incident in 2 hr over an area of 5 m2 will be = 7 kW x 2 hr
or
energy = 14 kWh
