Explanation / Answer
1. The temperature of the sun's core is 15 million kelvins. It is the hottest part of the sun and as well as our solar system.
2. The approximate value of the solar constant is 1.366 kilowatts per square meter.
The solar constant or S is the average amount of solar radiation per (unit area) received by the Earth's atmosphere. The amount of solar radiation depends on the distance between the Earth and Sun and also associated with the appearance or decay of sunspots.
3. The term that describes incoming solar energy per square meter of Earth’s surface is Solar Irradiance. Here the unit of power is watt.
4. the essential element in electronics and photovoltaic cells is the conversion process. In photovoltaic cells, sunlight is converting into electricity and in electronics, electrons are converting into electricity.
Hope this will help you.
