General description
-------------------
As the csv-reader was removed with version 0.2 this example shows how to create
an excel-reader. The example is equivalent to the old csv-reader example.
Following the example one can customise the excel reader to ones own needs.

The pandas package supports the '.xls' and the '.xlsx' format but one can
create read and adept the files with open source software such as libreoffice,
openoffice, gnumeric, ...

Installation requirements
-------------------------
This example requires oemof.solph (v0.5.x), install by:

.. code:: bash

    pip install oemof.solph[examples]
    pip install openpyxl


If you want to plot the energy system's graph, you have to install pygraphviz
using:

.. code:: bash

    pip install pygraphviz

For pygraphviz under Windows, some hints are available in the oemof Wiki:
