ᐅ Do photovoltaic systems and heat pumps share similar performance characteristics or operational experiences?

Hello dear forum members,
Since Monday afternoon, my photovoltaic system has been up and running, and I have to say... I can’t stop smiling.
Here are the details:
Today’s performance:
The gray line represents household consumption, the blue and red areas show production, where the blue part was self-consumed and the red part was sold.
You can clearly see the washing machine running in the morning, the regular starts of the heat pump, midday consumption, and even the not-so-optimally started dishwasher after 6 p.m.
For a (very good) day in March, I’m more than satisfied. The only thing is that the heat pump in the early morning isn’t yet running as efficiently as I’d like. But I guess only a battery would help with that, and that still seems uneconomical to me.

Here are the details:
- 5.4 kWp (18 modules at 300 W each)
- Peak power limitation 70% soft
- Flat roof, mounting angle 10°
- Orientation southwest, about 45° off south
- Feed-in to household electricity including heat pump
- Surplus energy sale
- no battery storage

Sorry, I’ll stick to my opinion that you presented this a bit confusingly in context.

It is presented as is, without any embellishment.

He didn’t hide the pool, and even if he had: self-consumption is still self-consumption, so you have to agree with him on that. It would be misleading if he had omitted a hydropower plant that also supplies electricity at night and included that in the calculations.
The self-consumption rate always depends on the individual situation—meaning which devices I have, the conditions on the roof, whether I control my loads based on feed-in, how many people are home at what times, and what they are doing.
Otherwise, a home office would fall under your confusing portrayal just like a pool, as if no one is home during the day in both cases. Then the self-consumption would actually be higher.

Sebastian795 Sep 2016 09:38How can people get so worked up about this – I was simply referring to the statement "should. Someone try to copy me" – I could set up a server farm myself and then my energy performance coefficient (EPC) would look great...
It’s nonsense anyway, but how quickly this person takes it personally… I find that more troubling.

But Musketier is right, there’s no point in debating it. Written statements should be taken without reading emotions into them, because that always leads to misunderstandings .
