Photovoltaic system offer for our single-family house

The alignment was after all:

"NRW 46562, 8 kwp southeast almost south, 4.2 kwp northwest almost north"

Even with now 14.4 KWp I see no relevant losses despite 70% soft - or am I mistaken?

Exact alignment - 40° and +140° So southeast and northwest. Solar installer says the 10 kW inverter is sufficient.

Therefore, in my opinion, you can save the nearly 1000€ for the Sunny Home Manager?!

Costs 690 € in the offer. Still thinking about whether I will have it installed. But it will be delivered at first.

Stupid question. Why is it then limited? I always thought that the excess is simply fed into the grid.

"Single-family house photovoltaic systems" are allowed to feed in a maximum of 70% of their kWp.
You can operate systems so-called "soft," meaning you can additionally still consume yourself.
With the inverter planned here, however, that is not possible.

Orientation was:

"NRW 46562, 8 kWp southeast almost south, 4.2 kWp northwest almost north"

Even with now 14.4 kWp, I see no relevant losses despite 70% soft - or am I mistaken?

What does "despite soft" mean?
Do you mean "despite hard"?
But yes, with the orientation, 70% hard should still be okay.

So southeast and northwest. The solar installer says the 10 kW inverter is enough.

That may be true. Did he simulate or calculate it, or is it just a feeling?

Costs €690 in the offer. Still thinking about whether to have it installed. But it will be supplied first.

Gross or net? Already money for a toy. ;-)
But at least a nice toy that might also encourage you to optimize consumption.

...
What does "trotz weich" mean?
Do you mean "trotz hart"?
For the alignment, 70% hard should still be okay
...

Thanks for the correction, that's exactly what I meant, but I'm no longer that much into the topic (my system is running anyway ;-) )

That may be true. Did he simulate it or calculate it or just have a feeling?



Gross or net? Already money for play. ;-)
But at least a nice gimmick that might then also encourage optimizing consumption.

calculated and the price is net

as I said, whether I have it installed or not is not yet decided, if it is not installed, it will not be charged

"Single-family house photovoltaic systems" are allowed to feed in a maximum of 70% of their kWp. It is possible to operate systems so-called "softly," meaning you can additionally consume yourself. However, with the inverter planned here, that is not possible.

I still don't understand. With a battery, less is fed in because more is consumed.
