What advantages does photovoltaics offer?
- The sun provides about ten thousand times the energy required worldwide.
- In contrast to fossil material resources, such as oil or natural gas, solar radiation does not have to be developed and transported first (like oil through oil drilling). It does not diminish when it is used but is available everywhere every day. As a result, energy production is also not politically and economically dependent on imports from countries that have fossil resources (such as oil), but can take place directly where the electricity is also consumed.
- The amount of energy required for the production of solar modules is amortised after only 1 to 4 years of use. This means that within this time the solar modules generate as much energy as was needed for their production.
- Silicon, the most commonly used raw material for solar cells, is the second most common chemical element on earth after oxygen and is therefore readily available.
- Photovoltaics contributes to environmental and climate protection as well as to health: Millions of tons of CO2 emissions are avoided, and pollutants and noise are not emitted during the operation of solar modules.
- The strengthening of the photovoltaic industry will create numerous new jobs.
- Photovoltaics has high cost-cutting potential. This means that further technological development can make production even cheaper and the prices for solar modules will continue to fall.
- Solar modules can be installed on existing roofs and facades. They do not take up any additional building space.
