What is solar power, why do we need to incorporate this into our lives, and how it is extracted answers to all such questions you will find in this article, this article is all about solar power, and its salient features.
Why do we need to incorporate solar energy into our lives?
Fuel price hikes, Incessant use of fossil fuels, that has caused the fossil deposits to deplete and have undesirable impacts on the environment like global warming. In addition to this increasing greenhouse emissions and occurrence of climate change due to this, expanding pollution rate, illicit forest cutting, and rising carbon dioxide levels giving more and more environmental concern. Exhausting of the ozone layer, liquefy glaciers, global warming, Rising electricity demands, and overuse of non-renewable resources to meet this, causing unfavorable crashes on the ecosystem.
According to research, it is found that a major part of the energy generation is done by using coal, that is via thermal power generation. But the use of coal has a very frightful impact on the environment. Somewhere along the way, it is devaluing the environment. Though we have a solution for all these concerns in the form of solar energy.
Solar energy is setting heights and proving more and more favorable these days, as it contributes to auspicious results such as pollution-free, cost-cost-effective, it is easy to extract, and abundant in nature, which makes it admissible in each direction. Looking at the insufficiency of these fossils and environmental concerns solar power is giving sustainable relief. What is solar energy and how it is extracted answers to all such questions will be given in this blog.
What Exactly Is Solar Energy?
Solar power as its name suggests is the power derived from the sun. Sun is the powerhouse of our planet, it provides an adequate amount of energy to keep up the balance. As per research by the US Department of Energy, about 173,000 terawatts of solar energy hits the earth’s surface uninterruptedly, which is way more than 10,000 times the world’s total energy requirement. The sun is a free, credible, and clean resource we can replace with the conventional electricity generation system. This solar energy hits the search surface in the form of solar radiation, which is in the form of light energy. These radiations later on converted to the electrical form using the photovoltaic effect.
What is the photovoltaic effect and how does it work?
The photovoltaic effect is responsible to convert light energy into electrical energy by some means. This conversion is take place by means of Semiconductors. This can directly transform light energy into electrical energy without any midway processes.
This phenomenon uses photovoltaic cells also known as solar cells to perform this action. Photons are present in the light energy, when these photons strike the solar cell material that is a semiconducting material with N-type and P-Type semiconductors, in a simple manner positively and negatively charged semiconductors, cause electrical energy generation. This semiconducting material excites electrons, and these excited electrons result in DC Which is a direct current generation. Further using an inverter this DC is converted to AC which is an Alternating Current to get the usable form of this energy because most appliances and household gadgets work on AC current.
Solar cell-solar panel and its type.
A solar cell, also known as a photovoltaic cell, is any medium or device that use to convert sun radiation that is light energy to use for which is electrical energy. This extraction of energy takes place using the photovoltaic effect.
A number of solar modules are used combined together to construct a PV array which is widely known as solar panel number. These nodules are constructed by joining many solar cells together. Approximately 60-70 solar cells are combined to form a single module. Wide variety of solar panels flourishing in the market Such as
- Monocrystalline solar panels,
- Mono PERC Solar panel.
- Polycrystalline solar panels (Poly-SI),
- Thin-film solar panels (TFSC)
