Dresden – Are our landmarks now turning into solar power plants?
Saxony’s Environment Minister Wolfram Günther (48, Greens) wants to promote electricity generation from clean energy with the “speed of Tesla in planning and approval”.
According to current figures from the ministry, only 10 percent of the energy consumed in Bavaria comes from wind turbines, solar systems and biomass, among other sources. Most electricity is still generated from coal.
There are currently 60,900 solar systems in Saxony. But there should be much, much more. And so SAENA, the Saxon energy agency with Minister Günther as chairman of the supervisory board, had a solar registry drawn up for a five-digit sum.
At www.solarkataster-sachsen.de everyone can now see which place on the roof of their house is the best place for a solar system and where the greatest amount of electricity can be produced.
Extraordinary: Solar surfaces were also determined and marked for monuments and landmarks such as the Dresden Frauenkirche, the Leipzig Monument to the Battle of the Nations or the Chemnitz Opera House.
According to SAENA’s calculations, 1,022 square meters of the Frauenkirche’s roof and dome could be used as a solar power plant.
Therefore, the solar church could produce 94,863 kilowatt hours per year and thus supply about 33 homes.
According to SAENA, a solar system of one square meter currently costs around 300 to 400 euros. On average, a solar system only pays for itself after several years.
As reported by the authority to BILD, a computer calculated the solar data of the buildings. If he had removed sights, churches and the like, it would have cost “several times”.
But that doesn’t mean solar systems are now being installed in our benchmarks.
According to the Ministry, the “owners of cultural monuments” would be subject to a “conservation obligation”, which includes treating them with care. But “this does not fundamentally rule out the use of roof areas for solar systems.” However, interests such as monuments or climate protection would have to be weighed.
