Hello everyone,

Another year has passed, which means it’s time to review how much electricity the photovoltaic system produced this year, how much of that was used for self-consumption, and how much was fed back into the grid.

System size: 3.12 kWp
Commissioning date: November 2016
Location: Lower Austria
Heating system: Air-to-water heat pump
No pool or other significant loads that could benefit much from the photovoltaic system

Produced amount: 3650 kWh
Self-consumption: 1000 kWh
Fed into the grid: 2650 kWh
Self-consumption rate: 27.4% (previous year 28.1%)

I am quite satisfied with the self-consumption rate.
I’m looking forward to your data and possibly some tips on how to improve it even further.

Best regards

What kind of timer do you use for this?
A Wi-Fi socket with an app?

No. A very basic mechanical timer like the ones you can find at any hardware store. I usually have it turn on around noon and off in the late afternoon. I might adjust it a bit depending on the weather forecast.

So you finish programming the devices, start them up, and then disconnect them from the power supply?

Exactly. Although calling it programming is a bit of an overstatement for our machine. It just has a mechanical dial to turn. Old technology really has its advantages here.
But of course, you can also satisfy your curiosity and do it via Wi-Fi.
The dishwasher has a built-in delay timer. We set it so that it runs around midday. New washing machines probably have this feature as well.

Our washing machine still has a dial ;-), but it already features the "ready in" function.
Let's see if our dishwasher can do that too; it's newer, so it should be possible.
