Planets in our solar system
The Solar System consists of the Sun and its planetary system of eight planets, their moons, and other objects including asteroids and meteors. Our planet Earth is one among the eight planets that revolve around the Sun.
It’s called solar system because the word solar means relating to the sun. Since Sun is the centre most part of this system, it is called solar system.
Concentrating solar power uses the sun’s rays to create thermal energy that is used to produce electricity, then store it for use when it’s needed. A SunShot Initiative project with Sandia National Laboratories is perfecting new technology that allows heat to be stored at higher temperatures, improving the efficiency of concentrating solar power plants and allowing utilities to provide customers with clean energy even after the sun has set.
