Principle Of Solar Energy Utilization
Oct 08, 2018

Solar energy is the energy produced by the continuous nuclear fusion process inside the sun. The average solar radiation intensity in Earth's orbit is 1367kw/m2. The circumference of the Earth's equator is 40,000 km, which makes it possible to calculate that the Earth can reach 173,000 TW. The standard peak intensity at sea level is 1 kw/m2, and the annual average radiation intensity at a point on the earth's surface for 24 hours is 0.20 kw/m2, which is equivalent to 102,000 TW of energy.
