Answer:
Explanation:
Solar Constant = 1.4 kW/m² (Given)
Solar energy received at area of 1 m² = 1.4 kW/m2
To calculate the solar energy we use over time, and multiply the power consumption by the hours of intended use. For example - an electronic having 20W that is on for 2 hours, will take 20 x 2 = 40WH from the battery.
Therefore,
The energy received at an area of 5m² = 5 × 1.4
= 7 kW/m²
Thus, the solar energy that will be received at this place per second over an area of 5m² is 7 kW/m².
