Solar Energy

Solar Energy In Homes, Solar energy Since ancient times, the inhabitants of the earth have used solar radiation in many different applications, including drying agricultural crops before preserving them, and heating homes and Archimedes used solar energy to burn the Roman military fleet in the year 212 BC, as he concentrated solar radiation towards the enemy’s army ships. Using many metal shields, and the women of the Babylonian era used golden vessels to focus solar radiation and obtain fire.

Many scientists have used solar energy to melt minerals, heat the air, convert water into steam, and distill water, and there are global irrigation stations using solar energy, and to the present day man is still devising renewable means to take advantage of solar energy by converting it to other forms.

The advantages of solar energy

• are a form of renewable and clean energy, and this gives it the advantage of environmental safety as it does not pollute the atmosphere, and it does not leave waste behind, which gives it great advantages compared to others.
• The technology that is used with solar energy is simple and uncomplicated compared to other energy sources that need the latest and most sophisticated technologies.

Solar energy conversion

Solar energy is characterized by that it can be converted to other forms of energy, such as electric energy and thermal energy, and uses photoelectric conversion technology and thermal energy conversion, and photoelectric conversion is a direct conversion of “light” solar radiation into electrical energy, which is done using solar cells. And in this case, it is important to use materials that work on photoelectric conversion, which are known as semiconductors, the most important of which are silicon and germanium.

This phenomenon was known by physicists in the nineteenth century to bring about a qualitative revolution in the concepts of physics, and from the valuable information that was known at that time that light has the ability to liberate electrons that are present in some metals, just as the blue light has that ability more than yellow light It is reported that Einstein received the Nobel Prize for his ability to explain this phenomenon in 1921 AD.

At the present time, the presence of solar cells, whether in homes, roads, or institutions and companies, has become an obvious matter. One of the most important features that distinguishes these cells is that they do not consist of moving parts, which makes them stable, and they do not need any kind of fuel, and are considered safe for The environment does not pollute the atmosphere, its life span is long and does not need frequent and expensive maintenance, and the principle of its operation is very simple, and its advantages are that it does not consist of any type of optical lens or light concentrators, so the solar panels are installed on the roofs of buildings in certain ways, and then benefit It is used for energy production, and its efficiency in energy production is equal to 20%, while 80% of it is used to provide heating heat, and in the process of heating water.

It can be used in the communication system, road lighting, and pumping water, and it is important to focus on the ability to benefit from solar energy linked to its existence, and for this reason scientists have directed to find special ways to save this energy, and there are many ways to store it, such as thermal, electrical, and mechanical storage. The chemist, and the magnetic.

Solar energy in homes

Solar energy is used in homes for many applications, the most important and most popular of which are home heating and water heating, and it can also be converted into electrical energy, and use it to operate some simple electrical appliances in homes, and at the present time, there are many experiences of using solar energy In home cooking means instead of using gas.
