+PyWatts - Predict Output of Solar Panels
+
+# Dependencies
+
+PyWatts is based on python3.6 and uses the following dependencies:
+
+* requests (2.19.1)
+* pypvwatts (2.1.0)
+* numpy (1.15.0)
+* peewee (3.5.4)
+* scikit-learn (0.19.2)
+* pandas (0.23.4)
+* tensorflow (1.9.0)
+* matplotlib (2.2.3)
+* scipy (1.1.0)
+
+We suggest using a python virtualenv.
+
+# Execute
+
+The script can be executed by issuing the follwing command:
+
+```bash
+$ python photovoltaic_gruppe4.py data.json
+```
+
+The output can be found in the same directory in `test_data_gruppe4.json`
