Solar systems under test - standards and developmentModern solar systems convert the sunlight into electrical energy. They work practically and make a big contribution to environmental protection.
Solar systems have many advantages over fossil fuels.
Advantages of solar systems
The cost of coal and oil is constantly increasing. In addition, their sources are gradually drying up. The sun's energy, on the other hand, has an inexhaustible capacity. It provides more energy in one day than humanity can consume. The solar technology exploits this potential for photovoltaic systems for the production of electricity and for solar thermal energy for heating water and as heating support.
Operation of solar thermal
The solar radiation heats up the heat transfer fluid in the system and delivers it to a second circuit. Here, the heat is evaporated by water, which can be a turbine driven. On sunny days, the system can also be switched to gas mode. This ensures a uniform power generation. Solar thermal energy is cheaper and more effective than photovoltaic systems. With the help of solar energy, buildings can be fully supplied with warm water and heating energy.
Photovoltaic systems and their importance
Photovoltaic systems are used to generate electricity for electrical appliances. There are large solar power plants that feed the electricity generated into the public grid and smaller systems for single or multi-family homes for private use. Photovoltaic systems are flexible and therefore independent of infrastructure and network connections.
Solar systems and their development
By the constant
Further development and the advancement of the technology could increase the effectiveness of the solar plants in the last years considerably. But solar energy can do more than produce heat and electricity. So-called solar ovens can produce a mixture of hydrogen and carbon monoxide from carbonaceous raw materials. With the help of solar energy, the mixture can be used as an effective fuel for heating. Solar fuels could also be used to power vehicles and thereby replace fossil fuels.
Promotion of solar systems
There are various subsidy programs for the investment of a solar system. The state supports the purchase of solar technology equipment through financial aid. In this way, the establishment of renewable energy is supported and additionally the environmental protection.
