Solar Power Plant

Summary:

Solar Energy is a renewable and abundant source of energy that can be harnessed for various purposes, including power generation, heating, cooling, and water heating. It is captured through different methods, such as photovoltaics, solar heating and cooling, concentrating solar power, and passive solar.

Solar radiation and irradiance are measured to determine the available solar power. Solar insolation measures the amount of sunlight on the Earth’s surface and can be converted into energy through various systems.

Photovoltaic systems directly convert sunlight into electricity using solar cells made of semiconducting materials like silicon. They find applications in calculators, wristwatches, lighting, communications, water pumping, etc.

Solar thermal energy systems concentrate sunlight to generate high-temperature heat, which powers heat engines to produce electricity. Solar thermal power plants use concentrating collectors, parabolic troughs, solar power towers, and solar dish/engine systems.

What is Solar Energy?
The sun’s energy is turned into thermal or electrical energy. It is the most efficient and abundant renewable energy source available. Today’s technology can harness it for various purposes, including power generation, lighting or creating a relaxing interior environment, and residential water heating for commercial or industrial use. Solar power has both challenges and potential; the industry is scaling up production while lowering
manufacturing and installation costs.

Solar energy harnessing has several ways:
1. Photovoltaics (Solar Electric)
2. Solar Heating & Cooling
3. Concentrating Solar Power (for utility)
4. Passive Solar

SOLAR RADIATION – is a renewable energy source with essentially no limits. The heat produced when a material absorbs electromagnetic radiation is used in the most basic form of solar energy technology. A pyranometer is used to measure it. This device was traditionally made up of a specific sensor consisting of numerous thermocouples inserted in a particular substance. The main goal is to absorb the entirety of the sunlight spectrum. The usage of a photoelectric sensor has become more frequent in recent years. While the spectrum sensitivity does not match the solar output and a typical instrument, it is adequate for most applications when calibrated.
