Generate the energy for your own consumption - and even much more of it.

That could be the new Lenggrieser nursing home in the future.

The municipal council has now paved the way for a solar roof on the new building.

Lenggries

– When it comes to the power supply of the new nursing home, Lenggries is now breaking new ground.

The roof will consist entirely of solar cells.

Some councilors were able to see for themselves what that could look like a week earlier at the on-site visit in Gauting.

Alexander Nazarenus from the Ennogie company explained the principle to all other councilors at the meeting on Monday evening.

"The thought behind it is: Why do you still need roof tiles, why not put the solar panels on the roof in one go?" The principle was developed in Denmark, but is now also enjoying increasing popularity in Germany.

The solar cells are installed directly and overlapping on a rainproof sub-roof.

The high-quality monocrystalline modules are covered with a water-bearing layer.

They are also safe from storms and hail.

On listed buildings, the modules are also possible in red, "but then they have less power".

On the roof of the Lenggries nursing home, for which an electricity consumption of around 125,000 kilowatt hours per year is assumed, the Ennogie modules could produce around 330,000 kilowatt hours a year.

Municipality wants assurance that roof will withstand snow loads

On behalf of the municipality, Matthias Welzer from an engineering office in Murnau compared the offer from “Ennogie” with a conventional solar system.

This would come to around 163,000 kilowatt hours per year.

While the conventional system costs around 560,000 euros, the one from “Ennogie” would be around 740,000 euros.

The solution of "Ennogie" had convinced the councilors who were in Gauting.

"But we would still like written assurance that the roof will also withstand the snow loads," said Mayor Stefan Klaffenbacher.

Anton Leeb (CSU) wanted to know why the central building of the nursing home was not planned with a solar roof.

The pitch of the roof there is too low, replied Klaffenbacher.

“We will then have considerably more electricity available than we need.

What do we do with him?” Leeb wanted to know more.

And whether there is a promise from the carrier, Caritas, that they will also take the electricity.

Yes, they talked about it with Caritas, said Klaffenbacher.

"There are considerations that we could also supply the neighboring house for the elderly.

But we will not be able to avoid feeding it into the grid.” In principle, Leeb thought the solution was a good one, it was “a coherent concept”.

Benedikt Demmel (CSU) wanted to know whether a solar roof could be opened in the event of a fire.

The modules could be dismantled individually, said Klaffenbacher.

"House of the elderly" could also be supplied

There is a precise cable plan, Nazarenus answered another question.

If there was a problem, it could be located immediately.

Even roofers and carpenters on site could easily climb onto the roof and carry out repairs.

Stefan Heiss (FW) was skeptical: A tiled roof would last much longer.

"At some point you have to replace every PV system," said Mayor Stefan Klaffenbacher.

Roman Haehl (Greens) would, contrary to the local design statute (OGS), allow such solar roofs on private houses if someone wanted it.

To do this, however, the OGS would first have to be revised, according to the mayor, who finally summarized: “We want to push ahead with the expansion of renewable energies.

We want the full-roof solar solution when we have the snow load data.”

The solution was voted against by the municipal councilors Stefan Heiss and Martin Willibald.

The call for applications will be made in a timely manner.
