Photovoltaic system Your yield in the year 2018

90% autarky

This group of terms around "autarky" in photovoltaic systems is, in my opinion, one of the biggest marketing deceptions that sometimes exist in house construction.
As soon as there is a grid connection, and just 1 kWh passes through the meter from or into the grid, you are exactly one thing: namely, no longer autark.

This group of terms around "autarky" in photovoltaic systems is, in my opinion, one of the biggest marketing deceptions that exist in house construction.

That's true, with my system with a battery, the evaluation also correctly states: "self-sufficiency rate in %" or self-consumption (of the generated electricity) in kWh. But with Porsche, they also call the new 911 Cabriolet a "Timeless Machine." It's certainly not entirely accurate, but so what? Anyone who wants such a thing buys it anyway :-) just like the photovoltaic system. Nobody really needs it and it doesn't make you self-sufficient either, yet some people just want to have it. There are more pointless ways to burn your money than with photovoltaics or even photovoltaics with a battery...

System size: 8.04 kWp
Commissioning of the system: August 20, 2018
Place of residence: S-H
Heating: Air-to-water heat pump

Produced amount: 1420 kW
Self-consumption: 482 kW --> 18 %
Fed in: 938 kW

Self-consumption rate could be better. However, we really had poor winter months here in the north in terms of sunshine. Additionally, my unfavorable roof angle of 28°, which is suboptimal in winter with the low sun.
In November I had 99 kWh and December only 36 kWh....there, however, 92.3% self-consumption.

System with 9.9 kWp in 91xxx from 2017 Generated in 2018: 10780 kWh Autonomy rate 44% All without storage. Large consumers such as dishwasher and washing machine operate according to timer during expected sunshine hours.

System 6.24 kWp in 37339 East/West, unevenly distributed as the east side also gets a lot of south exposure Generated in 2018: 6.16 MWh Sold: 5.1 MWh 17.2% self-consumption rate Could be better, but unfortunately not all parties in the house consistently operate consumers when the sun is shining.

All without storage. Large consumers like dishwasher and washing machine run according to a timer at expected sunshine hours.

What kind of timer do you use for that?
A WLAN socket with an app?
