Dear friends of renewable energies
Accompany me visiting the pv installations
on top of the roofs of the secondary school "Ludwig-Marum-Gymnasium" (Pfinztal, near Karlsruhe, Germany)
The owners of the first plant on top of the school canteen are:
The municipality "Pfinztal" and
The Renewable Energies for the One-World GmbH & Co. KG.
These two owners form a civil law partnership for the first installation.
The only owner of the second installation on the main building is the
(Renewable Energy for the One-World GmbH & Co. KG)
The owners of this enterprise renounce their profit from that installation. They donate the profit to
the association "Schöpfung nachhaltig bewahren" (i.e. Preserving Creation Sustainably)
With these donations the association finances projects that deploy renewable energies in Africa.
To get to the installation, we have to use a steep ladder and to pass through a passage.
Here we are on the roof.
Our tour leads us first to the solar field. These modules belong to the younger of the two installations.
This installation was built in 2008.
The total area is about 225 m² and the installation has a power of 30 kW peak.
The modules are oriented to south-south-west and have an elevation of 25 degrees.
These inverters transform the generated DC to AC (Direct Current to Alternating Current).
The older installation is on top of the school canteen and is not so easily accessible.
Therefore we can see it only from the far. That installation was built in 2006.
The modules are oriented to the south and have a power of about 15 kW peak.
The total area of the modules on the canteen is about 120 m².
The inverters and electricity meters are housed in a steel locker on the roof.
The two installations generated about 600,000 kWh so far. The energy was fed into the public grid.
With this energy you can serve about 21 average families in Germany for one year.
If you want to know more about the two installations and about the activities of the association "Schöpfung nachhaltig bewahren",
