# At midday, solar energy strikes the earth with an intensity of about kW/m2 . What is the area of a solar collector that could collect MJ of energy in h? This is roughly the energy content of gallon of gasoline.

Area of the collection is m2

See the step by step solution

## Step 1. Given information

The earth with an intensity kW/m2

## Step 2. Area of collector

We know that intensity of solar energy as power. Power that collector can be calculated as

From there we can easily required area of collector
