Concentrated solar power is today’s matter. This system use powerful mirrors to focus and increase the solar power. That’s why we say it “concentrated”. Solar energy, also called solar power, refers to the energy of solar radiation, which can be used by humans technically.
The use can take place in the form of electricity, as heat, but also as chemical energy. This is only possible through the nuclear fusion processes in the interior of the sun. By burning hydrogen on its surface prevail temperatures of about 5500 degrees Celsius, which meet as electromagnetic radiation partly on the earth’s surface.
How does concentrated solar power work?
While solar energy at the boundary to the earth’s atmosphere has an intensity of 1.367 kW per square meter. The so-called solar constant, the radiation energy on the earth’s surface hits “only” 0.114 to 0.268 kW per square meter, depending on the region. A large part of the incident solar energy is already absorbed or reflected by the earth in advance. Nevertheless, this “low” intensity on the earth’s surface is sufficient for man to use it technically in different areas of the energy supply.
How efficient is concentrated solar power?
We see that concentrated solar power is really efficient when compared standard production. Since solar energy can be measured at all, the sun emits an almost constant radiant energy. Serious fluctuations are not known even from times long past. Thus, solar energy represents an almost limitless source of energy that, unlike fossil fuels, is hardly exhaustible. The sun, or solar energy, is therefore the largest, available energy source of humanity and with modern solar technology in different energy ranges for humans usable.
How much does concentrated solar power cost?
When we take a look at the concentrated solar power costs, we see that average cost is $0.08 per kWh. Solar energy can be used, for example, by means of solar collectors for heat generation, generated within solar thermal power plants with the aid of steam electricity or is used for DC generation by photovoltaic systems. However, solar energy or solar radiation is subject to daily, seasonal and regional fluctuations. Theoretically, a solar farm covering an area of 700 x 700 kilometers, set up in the sun-drenched Sahara and with an efficiency of only 10 percent, would be enough to cover the global total energy demand.
