Solar balcony/balcony power plant/Plug&Play PV plant - after one year of operation

I had planned to install a PV system on our house. Unfortunately, the Stadtbildkommission in Basel-Stadt still blocks an economic implementation by excessive requirements in our residential district. These make the installation of the PV so expensive that it is not economically feasible even with funding.

For this reason, I installed a so-called Plug’n’Play solar system a year ago. See contribution from last year.
Of course, this still with the hope that the regulations will loosen up at some point and I can realize a roof PV with the maximum possible use of the roof area in the future…

My panels point east as our house has an east/west orientation. In nice weather I have direct sun on it between about 08:00 and 13:30 and in the second half of the day the diffuse light in the house shadow.

My expectation for one year of operation was between 250 and 300 kWh/year. So about 7% of my annual consumption. So around the 100-120.- SFR savings
Through the winter I doubted this goal. The daily yield in cloudy skies and cloudy weather was sometimes very sparse.

The screenshot after one year has now shown that the bill was not completely wrong for the whole year. I am, of course, very pleased about that.
If the panels were oriented to the south, the yield would certainly be much higher.

With around 400.- SFR investment costs, the plant is amoticized with this yield after 4 years. I think that’s a good calculation. Of course, I still want to relax the requirements in order to be able to install a decent system. But until then I have at least a small part of self-generated electricity in the house :
