Key facts about solar electricity
Are you interested in solar electricity and would like to have a quick overview of facts? You can find all key information here.
In what way do I protect the environment with solar electricity?
A solar power system not only allows you to become less exposed to ever-increasing energy costs, but also enables you to protect the environment, as electricity generated by a solar power system eliminates many tons of CO2 emissions. In Germany, for instance, 700 grams of CO2 are emitted on average to produce a kilowatt hour of household electricity in coal, gas and nuclear power plants. In contrast, a solar power system cuts emissions by 569 grams per kilowatt hour and year. Thus, 3.6 million tons of CO2 were eliminated in 2009 as a result of all the installed solar power systems.
What is solar electricity? And what are photovoltaics?
Photovoltaics is the direct conversion of solar energy into electrical energy. The term 'photovoltaics' is made up of the word 'photo' – the Greek word for light – and 'volta' – after Alessandro Volta, a pioneer in electro-technology ('photovoltaic effect').
