Question

How much solar energy will be received by 1 m2 area in one hour if the solar constant be 1.4 kW/m2?

Answer 1

Answer:

Total energy received in 1 hour = 5040 kJ.

Explanation:

In the given question,

The value of Solar constant = 1.4kW/m² = 1.4 kJ/s/m² .

Now,

The Solar energy received in 1 hour on 1 m² of Area = Value of Solar Constant x Time in Seconds

Area = 1 m².

Now,

Solar energy received on 1 m² area in 1 second = 1.4 kJ (Solar Constant)

So,

Total energy received in 1 hour = 1.4 kJ x (60 x 60)

Because,

1 hour = 3600 seconds.

Therefore,

Total energy received in 1 hour = 1.4 kJ x (3600) = 5040 kJ

Answer 2

Total energy received in 1 hour = 5040 kJ.

Explanation:

In the given question,

The value of Solar constant = 1.4kW/m² = 1.4 kJ/s/m² .

Now,

The Solar energy received in 1 hour on 1 m² of Area = Value of Solar Constant x Time in Seconds

Area = 1 m².

Now,

Solar energy received on 1 m² area in 1 second = 1.4 kJ (Solar Constant)

So,

Total energy received in 1 hour = 1.4 kJ x (60 x 60)

Because,

1 hour = 3600 seconds.

Therefore,

Total energy received in 1 hour = 1.4 kJ x (3600) = 5040 kJ
