INTRODUCTION
Solar energy is the energy generated by sunlight, photovoltaics and heat which is also known as solar thermal energy. It is used to generate electricity or heat. Inexhaustible and renewable as it comes from the sun, solar energy is used through panels and mirrors. It is inexhaustible and renewable as its source is the sun. Solar energy is observed and used through solar panels and mirrors. Photovoltaic solar cells convert sunlight directly into electricity through what is known as the photovoltaic effect.In which certain materials are able to absorb photons (light particles) and release electrons, creating an electrical current. Whereas, solar collectors use plates or mirrors to absorb and concentrate the sun’s heat. Transfer it into a liquid and guide it through pipes that are used in buildings and systems as well as for generating electricity (solar-thermal-electric).
WHY IS SOLAR ENERGY IMPORTANT?
1. Renewable:
Compared to standard energy sources equivalent to coal, gas, oil and nuclear reserves, from those clean energies are finally even as offered because of the sun. From which they originate and which adapt to natural cycles, hence the name “renewable”. Component of a property energy system that permits development nowadays while not endangering that of future generations.
2. Competitively Increasing:
Nowadays renewables, specifically wind and electrical phenomena, are cheaper than standard energies in abundance in the world. The most renewable technologies – appreciate wind and star photovoltaic – are drastically reducing their costs. Such that they’re totally competitive with conventional sources in a very growing range of locations. Economies of scale and innovation are already leading to renewable energies changing into the foremost property solution, not solely environmentally however additionally economically, for powering the world.
3. Non-Contaminating:
Solar energy does not emit harmful or polluting substances into the air that can be terribly harmful to the atmosphere and humans. Pollutants can acidify terrestrial and aquatic ecosystems and corrode buildings. Air pollutants can cause heart disease, cancer, and metabolic diseases such as asthma. Solar energy does not generate waste or pollute water, an issue that is critical in the face of water scarcity. Unlike fossil fuels and nuclear power plants, wind power has a single water usage footprint at the bottom, making it a key to conserving water resources.
4. Promotes wealth and jobs:
In addition, wind energy is “indigenous” energy as it is available practically everywhere in the plant. Which makes it possible to reduce energy imports and create local prosperity and jobs. to sustainable development.
Solar energy, on the other hand, will never die of shining, since the Sun still has 6.5 billion years of life in line with NASA. Indeed, in rather less time, star technology in some countries has evolved to contend with typical sources of electricity generation. In precisely a couple of decades’ time, it’ll become the key part of a property energy system for the world.
Additionally, the conditions for the event of solar power couldn’t be perfect: The Sun bathes the world hourly with enough light-weight and warmth to meet international wants for a full year; in alternative words, radiation will satisfy our energy needs 4,000 times over.
NEW TECHNOLOGIES INTRODUCED IN 2021:-
There are 5 solar power technologies that have been introduced in this year itself which are as follows: –
- Building Integrated Photovoltaics.
- Floating Photovoltaic Solar Panels.
- Thin-Film Solar Cells.
- Solar Lighting.
- Photovoltaic Noise Barriers.
Many buildings have surfaces that would simply contribute to alternative energy while not detracting from their image. The aesthetic attractiveness of Building Integrated Photovoltaics (BIPV) could dramatically increase the employment of star energy. Custom-made panels are already being fitted into fine arts options reminiscent of anopies and terraces. However, the foremost versatile product is PV glass. It’s factory-made from clear electrical phenomenon cells. The PV glass is toughened and lets daylight enter a building whereas manufacturing energy unseen. It’s a feature which will easily be put in once refurbishing an advertisement space. Imaginatively incorporating solar power into design has several advantages. There’s an infinite supply of energy, shrivelled maintenance costs, improved sound insulation and thermal optimization. It’s an excellent step towards a zero-carbon footprint.
Floating Solar Panels
Lakes and reservoirs have some of the largest areas available that have the potential to generate solar energy. A big advantage is that floating photovoltaic solar panels produce huge amounts of energy without occupying valuable land or real estate. The first commercial use of floating solar panels was in Japan in 2007. Photovoltaic solar panels generally use an air cooling system to prevent them from overheating. But in the floating version, water was found to increase electricity production by 10%. This was due to the cooling effect of the water under the panels.
The cost of maintaining the panels of a floating system is cheaper. This is because the water helps the panels to stay clean from dirt. In addition, the management of lake or reservoir water inadvertently becomes more practical. The shadow cast by the panels helps considerably to reduce the excessive formation of algae. The extent of floating solar panels considerably reduces the evaporation of water.
