It was first used by a random dude that invented it and now we use it, and we made it better, and blah blah blah.
Solarthermally:
The French mathematics teacher Augustin Mouchot patented in 1861 the first machine, which could produce electricity by the exposure of the sun. Mouchot filled, with a glass layer surrounded, iron bucket with water. Those, between the iron and the glass, caught sunbeams, let the water evaporate. The developed steam propelled a small engine. Augustin Mouchot perfected its machine as he added large, dish-similar mirrors which were directed toward the iron container. The mirrors should bundle the sunlight and thus more steam produce. Besides Mouchot adjusted the mirrors, with the help of two axles, constantly to the sun, in order to increase the warmth between the glass and the iron constantly (such mirrors are used today in California.). The energy, which Mouchot's machine produced, was however in such a manner low that further with the cheap coal electricity was won.
Spain, the United States and China all have solar panel thermal stations. Though it is unclear where the first station was built.
CERES is the first and the biggest asteroids in the solar system
Aristotle was the first the theorize that Earth was the center of the solar system.
Pluto is a member of the solar system because any object in the solar system is a member of the solar system. However, if you were asking if Pluto is a planet in the solar system then the answer is no. Pluto used to be a planet but is now considered a dwarf planet.
Yes, a solar powered portable heating system can be used.
Telescope
The sun is the first and only star in the solar system.
mecury is first in the solar system
There are a few steps of a solar system project. You first have to study the solar system.
CERES is the first and the biggest asteroids in the solar system
Not in my solar system.
The first planet in the solar system is Mercury
That depends on what definition of first you mean. A solar system is in a galaxy and a galaxy is in space. So the solar system is smallest and space is largest.
As soon as there was a solar system.
If we are talking about being off the Earth and in the solar system Yuri Gagarin.
The current model of the solar system was first conceived by Nicolaus Copernicus, but the idea of a heliocentric solar system was known to the Greeks of antiquity.
the solar system is measured in what are known as light years
Mercury is the first planet in our solar system.
