How much solar energy will a 1 m2 area receive in one hour if insolation = 1 kWm-2? Class 9


Question 1.

How much solar energy will a 1 m2 area receive in one hour if insolation = 1 kWm-2? Class 9

Answer:

Using: E = Intensity × Area × Time

E = 1000 J s-1m-2 × 1 m2 × 3600 s

E = 3,600,000 J

E = 3.6 × 106 J
