Photovoltaic installations on new buildings offer potential for 78 billion kWh of solar power generated and 44 million tons of CO2 savings. This is according to a study.
The roof surfaces on German new buildings offer a large solar power potential, as a new analysis of Eon data experts and the think tank Energy Brainpool shows: If every new single-family, semi-detached and terraced house built within the next 15 years were equipped with a rooftop PV system, a total of 78 billion kWh of green electricity could be generated in this period. In 2036 alone, these systems combined would generate 10.38 billion kWh, enough electricity to mathematically meet the annual electricity needs of more than 4.1 million average private households.
"The photovoltaic potential for rooftop systems is enormous. Within the next 15 years, solar installations on newly built houses could save a total of 44 million tons of CO2. It is therefore right that the German government wants to make the installation of PV systems in new residential buildings the rule," explained Filip Thon, CEO of Eon Energie Deutschland. In addition, there are still numerous suitable but previously unused areas on many existing buildings and in the commercial sector.
For this calculation, Eon and Energy Brainpool have taken as a basis that in the coming years just as many single-family, semi-detached and terraced houses will be completed as in the average of the past five years.
