- India became the third largest country in solar energy production.
- The installed solar power capacity has reached 136 GW.
- Solar panels convert the sun’s rays into electrical energy.
- Three main types of solar panels: mono, poly, and thin-film.
Solar Energy Technology: Solar energy is expanding rapidly in India and in the last few years India has become the third largest producer of solar energy. Now it has become common to see solar panels everywhere from big cities to villages. According to the latest government data, India’s installed solar power capacity has now reached about 136 GW and is continuing to grow. Amidst all this, it is important to understand how electricity is generated from the sun’s rays. Today we will know how electricity is generated from solar energy and what is the use of solar panel in it.
How is electricity made from sun rays?
Solar Energy Technology converts the rays coming from the sun into electrical energy. This can be done through photovoltaic (PV) panels or mirrors, which concentrate solar radiation. This energy can be used to generate electricity and it can also be stored in the battery. Solar panels are used to capture the rays coming from the sun.
What is the use of solar panel in generating electricity from sunlight?
Solar panels are used to generate electricity from sun rays. Solar panels consist of silicon cells, metal frame and glass casing, which is covered with special film and wiring. They are set in a special format facing the sun for maximum electricity production. The cells in it are also called photovoltaic cells. These cells absorb sunlight. Then this light energy is converted into electric current. Electricity is generated from the electric current collected from all the cells.
How many types of solar panels are there?
There are mainly three types of solar panels – monocrystalline, polycrystalline and thin film. The way they all work is the same, but they differ on the basis of design, performance and price. Talking about thin film, these are light and flexible panels and their price is also low. It is the right choice to meet low load and portable requirements.
If we talk about the remaining two, the main difference between monocrystalline and polycrystalline is the cells. Monocrystalline panels use solar cells made of single crystals of silicon. These black looking panels have the highest efficiency and their price is also higher than the others. Talking about polycrystalline, solar cells made of many melted fragments of silicon are used in it and they are blue in appearance. These are slightly cheaper, due to which they are used in residential and commercial projects.
