What Is Solar Energy?
The sun’s electromagnetic radiation (including its visible light, infrared heat, and ultraviolet rays) helps to generate electricity. It creates heat energy (photothermal) or electricity (photovoltaic) by setting up solar panels or collectors.
Solar energy, one of the most prominent renewables, is essential to the change. It contributes to cleaner economies that safeguard the environment, increase people’s well-being, and assure business sustainability.
Solar power is the most efficient and cheap renewable energy sources due to technology. Besides contributing to the planet’s sustainability, this limitless energy source draws investment, generates employment, and boosts corporate competitiveness.
At a time when protecting the planet is a top issue, we should know the many forms of solar energy, how they work, and how their usage as a source of power production can expand.
Types Of Solar Energy
Photovoltaic Solar Power
This energy is collected using a photovoltaic system, which converts solar radiation directly into electricity. When exposed to sunlight, the photovoltaic cells of solar panels ionize, releasing electrons that interact with one another to create an electric current.
With the emergence of solar communities and the energy savings brought forth by new solar self-consumption installations, PV solar energy has gained considerable popularity in recent years.
Thermal Solar Energy
Solar collectors in solar thermal equipment convert solar energy into heat. These collectors capture and store solar power to heat water to support heating or hot water systems for sanitary, residential, or industrial purposes.
Another alternative is Concentrated Solar Power (CSP). Sunlight is focused on a surface using lenses or mirrors in this scenario. The energy produced by this process is utilized to create electricity by boiling water to produce steam and power, for example, the turbines of a generator.
Passive Solar Power
In this case of passive solar power, the sun’s energy is directly captured via materials and building solutions rather than converted into other forms of energy, as in earlier situations (which may be termed active).
Passive solar technology is an essential component of ecodesign and bioclimatic architecture, and its primary use is heating living areas. Natural illumination, whether direct or through light tubes (with mirrors within), is another example of passive solar power utilization.
Hybrid Solar Energy
In this situation, any of the sources above of solar energy are coupled with other renewable energies to increase the energy supply.
The most obvious example is the use of solar and wind energy together. Utilizing both the sun and the wind, hybrid photovoltaic and wind systems maximize energy production.
