A coalition of 18 organizations urged EU member states to set requirements for the installation of solar energy in all new, renovated and existing non household buildings.

In a letter recently sent to the EU Energy Minister and the European Parliament, the signatory wrote that accelerating the development of solar energy in buildings is crucial to supporting the energy security in the coming winter and improving the resilience of the European energy system.

In order to maximize the potential of this initiative in the EU Building Energy Efficiency Directive, the letter urged the installation of solar energy in all new and renovated buildings.This letter was signed by SolarPower Europe, a trade agency.

The letter quoted data from the European Joint Research Center that building solar PV can meet 25% of Europe's annual power demand, which is equivalent to the sum of power consumption in Germany and Poland.

According to SolarPower Europe, at present, seven EU countries have mandatory regulations on solar energy for renovated buildings and nine countries have mandatory regulations on solar energy for new buildings. "Now is the time to make it the norm of the European Union."
