Technologies for harnessing solar energy.


It’s difficult to efficiently use the sun’s energy. Because of how pervasive the sun is, finding the best method to capture it necessitates sophisticated knowledge and technology. Utilizing solar energy is possible through a variety of technologies, each of which is distinct and tailored for a particular application.

The photovoltaic cells, also referred to as solar cells, come first. These are most likely the most popular method of using the sun’s energy. The first thing that comes to mind when someone mentions solar energy is having countless photovoltaic, or PV, panels. These cells contain semi-conductors, which are typically made of silicon and absorb solar light. New free electrons are produced when sunlight strikes silicon’s surface. Electric current is produced as the electrons are directed out of the silicon.

Concentrating solar power systems are the second type of solar energy technology. This one uses mirrors to direct sunlight to a specific area. Some systems use sophisticated tools to monitor the sun’s path and modify the mirrors to increase the amount of sunlight the system receives. A conventional power plant is heated or powered by the sunlight that is reflected by the mirrors. Other systems direct the mirrors’ light toward a collection of photovoltaic cells.

The solar trough, parabolic dish, and solar power tower are the three most well-known types of concentrated solar power systems. The solar trough directs sunlight toward a tower at the center of the mirrors using sizable U-shaped (parabolic) reflectors. The sun’s energy heats hot oil in the center tower, which helps boil water to produce steam that powers convention plants.

Similar to solar troughs, the power tower system makes use of this idea. Mirrors are used to reflect sunlight into the center tower, where a heated liquid is used to produce steam that will power a power source. The parabolic dish system concentrates and focuses sunlight onto a receiver using mirrored dishes. The dish’s dimensions can vary, but it is typically 10 times larger than a typical cable satellite dish.

The solar water heating systems that are currently in use are another solar power technology. This one is easy. The process involves directly capturing solar energy to heat liquids or water, which then heats the water. This is more typical in homes that are great for families.

Solar panels must be installed in your home or in a location where you will need hot water, such as a swimming pool area, in order to capture the sunlight. Although a large space is required for this, in the long run you will be able to significantly reduce your electricity costs.

The transpired solar collector, also known as the solar wall, is the ideal solar energy technology for commercial buildings. Perforated solar collectors are used, through which outside air is allowed to pass before entering the building.

These are just a few of the available technologies that can be used to harness solar energy. As new innovations and discoveries are made, solar energy harvesting technologies also continue to advance. Things could change drastically in a few years. Additionally, the cost of all solar power technologies will decrease, which will benefit ordinary consumers.
