Question

The solar constant at a place is 1.4 kW/m² . How much will solar energy be received at this place per second over an area of 5 m²?

Answer 1

Given: 

Solar Constant = 1.4 kW/m² 

Solution: 

Solar energy received at area of 1 m² = 1.4 kW/m² 

So the energy received at an area of 5m² = 5 × 1.4 

= 7 kW/m²
