How much energy does a solar roof generate in Europe?

It is estimated that solar roofs could generate about a quarter of the EU’s electricity consumption, i.e. more than the share of natural gas used in the European energy mix. The European Solar Roof Initiative announced in the framework of REPowerEU aims to rapidly exploit this potential.

How much solar energy is needed in Switzerland in 2024?

In Switzerland: Solar obligation for new buildings with more than 300 m2 from 2024 (approx. 30% of new private buildings). The UReK-S (the Environment Commission of the Council of States) wants to accelerate the expansion of solar energy. According to the commission, electricity production urgently needs to be increased.

How will new solar regulations affect Switzerland's electricity grid?

“The new regulations encourage the temporary storage of solar production peaks, which helps relieve the electricity grids,” said Swissolar. Switzerland installed approximately 1.78 GW of new PV capacity in 2024, according to provisional figures from Swissolar.

How many buildings use rooftop solar?

Despite consuming 40% of global energy, relatively few buildings take advantage of the free energy source shining down onto their roofs. Less than 1% of US buildings have rooftop solar. This is rapidly changing. Pushed by changing regulations, solar panel use on commercial buildings is expected to double in the EU by 2050, for example.

What is the European Solar Roof Initiative?

The European Solar Roof Initiative announced in the framework of REPowerEU aims to rapidly exploit this potential. To achieve this, the Commission calls (in a note published in August) for necessary measures by the end of 2022. Under its latest guidelines, it states that:

How much energy does real estate use in Switzerland?

Now, private real estate (households and service companies) accounts for 40% of energy consumption in Switzerland and about one third of CO2 emissions (which are due in particular to heating systems).
