Solar Mirrors.


Here is an example of A Solar Mirror Farms

Below are some Frequently Asked Questions:

1) What are Solar Mirror Farms for?

Solar Mirror Farms are used to focus concentrated rays of the sun’s radiation onto solar panels on a large tower, granting a larger output of electricity.

2) How is this method efficient as opposed to setting up solar panels throughout the ground?

Solar Mirror farms are self-sufficient, and save space. The light is reflected off the mirror, into a fluid-filled tube, which is then used to heat steam which runs the turbines, utilizing solar power to its maximum potential.

3) How is it ensured that the mirrors receive the maximum possible sunlight throughout the day?

The mirrors face south, and as the sun moves, it turns to face the sun as it moves from east to west, ensuring maximum possible output.

4) How does it compare to other power plants?

Solar Mirror Farms are equally if not better in providing electrical energy, solar energy collected by the panels convert it to electricity, while the rest which is reflected into a fluid-filled tube converts the heat energy of the sun to power turbines, making it energy efficient as well as being eco-friendly.

5) Why is it that not many solar mirror farms are available throughout the world?

Other countries either lack the money needed, or the land area required for large solar mirror farms. Also, many factors, such as rainfall, amount of sunshine throughout the year affect the practicality of solar power, as well as its usefulness and output, for example, Singapore does not have the land area required, countries such as Russia do not face constant sunshine, despite having a large land area, as well as Egypt, which despite having a large amount of sunlight, the environment of dust and such affects the productivity and maintenance cost of the solar mirror farms.

Solar Mirror Farms

Solar Mirror Farms are firstly introduced by Spain, which created the first largest solar power station. Overtaking the United States. The above pictures come from Spain’s solar mirror farms. These Solar Mirror Farms produce more solar energy than that of the United States, supplying 3% of its country’s electricity, the internal systems of following the sun as it rises and sets increases output and practicality, making Solar Mirror Farms a reliable solution for Spain’s growing demands for electricity.

Solar Mirror Farms concentrate large amounts of sunlight onto the panels, enough to make the surface of the panels reach a maximum of potentially 3600 degrees Fahrenheit, of which the steel and receiver which would melt down then, and whereby the mirrors are required to be directed away from the solar panel, the only flaw in this system.

Despite this flaw, Spain has found a way to put the excess sunlight to good use, using the reflected light to heat up large tanks containing differing types of nitrates, storing up to 570 degrees Fahrenheit up to 6 hours, allowing for energy to be stored for the night.


First Solar Power Farms

These are the First kind of Solar Powered Farms, they are very different from Solar Mirror Farms and comprise of the simple design of covering the ground with large amounts of solar panels seen above, this often requires huge land areas, as it is designed to absorb all light within the large area used for solar panels, the typical way in which solar power plants are developed.

These Solar Power Farms are not as energy efficient as Solar Mirror Farms, which produces good if not better results with the same amount of landuse, as well as being cheaper due to using mirrors to reflect light onto the much smaller amount of solar panels, concentrating light rather than just placing Solar Panels across the area receiving diffused light and is more expensive. Solar Mirror farms also utilize the heat energy from the sun’s rays to heat up the air and power turbines which generate electricity. Whereas, the first Solar Powered Farms utilizes the large land area the country has and uses it to generate electricity. Solar Mirror Farms, despite having its advantages, loses out to the First Solar Powered farms as it gets bigger as despite being cheaper, the Solar Panels can only handle a certain amount of temperature due to the side effects of heat from the sun’s rays, therefore limiting maximum amount of radiation shone onto the solar panel, lowering the maximum possible amount of electricity produced.

However, the initial Solar Powered Farm, though more expensive, is equally beneficial in that it allows for maximum production of electricity, without being limited by factors such as heat, thus the most beneficial farm in the long term in a very hot country would be the initial Solar Powered farms, not facing the problem of overheating, however for areas with moderate sunlight, the most effective one would be a Solar Mirror Farm, as it allows for the greatest productivity for a lower cost, and the chances of overheating are much lower.
