Photovoltaic power energy
The sun reaches us with enough energy every minute to meet the energy needs of the entire world population for 1 year. Unlike fossil fuels, sun energy is a sustainable and lasting solution. Almost no CO2 is released with photovoltaic energy. The little CO2 that is nevertheless released is due to the production of the PV panels. The sun energy itself is emission-free. That is why opting for clean energy is a wise choice.
Photovoltaic power energy
Thanks to favorable measures, but especially due to the constantly rising energy prices, both individuals and companies are increasingly interested in alternative energy sources. The demand for PV systems to generate green energy will certainly increase in the future. On our site you already get some idea about the form of a complete system.
- Fusion reactions take place in the core of the sun, whereby hydrogen is converted into helium. As more helium is added, it starts to shine more and more powerful: 10 percent more powerful per 1 billion years.
- In 1 billion years our star seems so strong that all the water on the surface of the earth evaporates and life as we know it ceases to exist.
- The sun appears yellow from the earth. However, this is because our atmosphere blocks some of the color-giving photons that the star emits. Seen from space it is white. In fact, it contains photons in all colors that we know. You can see that in rainbows and when the light is broken by a prism.
- In 2012, a research team from the University of Hawaii succeeded in measuring the difference between the diameter of the sun at the equator and at the poles. Although it has a diameter of 1.4 million kilometers, the difference between the horizontal and the vertical cross-section is only about 10 kilometers.
That means that if the sun were to be as big as a beach ball, the difference between the equatorial diameter and that between the poles was smaller than the thickness of a human hair. This makes it the most perfect naturally shaped sphere that we know.
- On the surface of the sun the temperature is around 5500 ° C. That's pretty hot, but nothing compared to the temperatures on the edge of the star's atmosphere, the corona. Here it can be between 1 and 3 million ° C.
- In a eclipse, the moon stands between the sun and the earth, covering the sunlight. The fact that sun eclipses can occur is purely coincidental.
It is 400 times as big as the moon, but the moon is exactly 400 times closer to the earth than the sun. As a result, it is possible that the much smaller moon completely covers the sun.
- If our star is twice as old as it is now, it will have used up all its hydrogen and will turn helium into carbon. This increases the size and makes it a different type of star: a red giant.
