Solar energy is already being used heavily in many parts of the world. And it has the potential to produce energy many times more than today's global energy consumption if utilized properly. Solar energy can be used directly to generate electricity or for heating. Or even cooling The future potential of solar energy is only limited by our willingness to seize that opportunity.
There are many ways that solar energy can be used. Plants convert sunlight into chemical energy using photosynthesis. We take advantage of this energy by eating plants and burning firewood. However, the word “Solar energy” means direct sunlight, rather than heat, or electrical energy for use. The basic types of solar energy are "solar thermal power" and "solar cell".
The process of solar cells is to produce electricity from light. The secret to this process is the use of a semiconductor that can be optimized to release electric charge. Which is a particle that is charged at the negative electrode This is the basis of electricity.
The most commonly used semiconductor in solar cells is silicon. Which is a common element in sand Every solar cell contains two layers of such semiconductor. One layer is slotxo เล่นฟรี charged at the positive terminal. The other floor is charged on the negative terminal. When light shines on a semiconductor The electric field passing through Part II, this layer intersects, allowing electricity to flow Causing an alternating current The stronger the light shines The more electricity is flowing.
Therefore, photovoltaic systems do not need bright sunlight to operate. It also produces electricity on cloudy days, as it produces electricity proportional to the density of the clouds.Plus, less cloudy days produce more energy than cloudy days. Because the sunlight is reflected from the clouds
It is common now to use very small solar cells to power small devices such as calculators. In addition, solar cells are used to generate electricity in areas without power transmission lines. We have developed a refrigerator called Solar Chill that can be operated using solar energy. After testing, it will be used in human rights organizations to help provide vaccine services in areas without electricity. And it will be used by those who don't want to rely on power transmission lines to keep food cool.
Architects are increasingly making use of solar cells as a key design feature. For example, tile or slate roofs with solar cells can be used as a replacement for conventional roofing materials. Flexible thin films can be incorporated into parabolic roofs. While the semi-transparent film creates a blend of shadows with daylight. In addition, solar cells are able to produce the most energy for buildings on hot summer days when air conditioning systems require the most energy. Therefore, it reduces the electricity condition to increase the maximum quantity.
Both large and small solar cells can power transmission lines. Or work on its own
