Photovoltaic system, using experiences like a heat pump?

The mounting system is likely to cost around 200 euros/kWp, and the actual local providers were another 200-250 euros/kWp more expensive!

However, I did not choose the cheapest provider either.

The modules come from Taiwan and are not part of the cheap Chinese production, the rest of the technology is from Austria.

Yes, the subsidy fund repayment grant KFW 153.

I am still analyzing and adjusting the system, as the inverter shuts off without sunlight and does not record self-consumption at night.

Therefore, I need a few more days until I know.

But except for the heat pump in the morning and evening hours, we manage to achieve almost 100% self-sufficiency during the day.

Yes, the funding pot Repayment Grant KFW 153.

However, KfW 153 is not directly related to "Energy-efficient Building - For construction or first purchase of a new KfW Efficiency House."

We are also currently looking into what concepts and options are available here. Among other things, it seems possible to receive grants from the BAFA for "Heating with Renewable Energies."

Hello,

Loan program 274 is the keyword plus recently again 25% of the battery costs until the end of June 16, such a battery is to be installed. After that, the share of funding is reduced to 10% until the end of 2018.

Rhenish greetings

An exciting topic. I have dealt with it now and then. If something like that is worthwhile in Northern Germany with a storage battery, I would do it immediately. How do I find reputable providers in my area to get advice?

Thank you, construction expert.

So a subsidy is only available if you build with storage. Without storage, you have to compare the conditions, I believe for a fixed 10 years they are around 1.25%, so not really lucrative.
Somewhere I once read as a restriction up to a maximum of 2 residential units, but I can't find the passage right now, maybe it was another program.

Hello dear forum members,

since Monday noon I have my photovoltaic system in operation and how shall I say... I can't stop grinning.

Details:

[*]5.4 kWp (18 modules at 300W)
[*]Peak control 70% soft
[*]Flat roof, mounting angle 10°

[*]Orientation southwest, i.e. 45° turned away from south.
[*]Feeding into household electricity including heat pump
[*]Surplus sale
[*]no storage

Our performance today:
21.29 kWh

Hello Toxi,

now I may tease you a little or put a small damper on your joy .
We have a system with 5.36 kWp almost perfect south orientation (gable roof) and had yesterday a (for early March super great) production of

29.12 kWh.

Sorry - I couldn’t resist, because yesterday I myself was left open-mouthed when I saw it.
Probably due to the slight inclination of the mounting.

I think your display is not bad. My inverter is much simpler. It only shows the production.
Do you also get the value (number kWh and % of production) for self-consumption delivered? I always have to determine this using an Excel sheet.

Is your dishwasher programmable?
I start the cleared dishwasher in the morning (around 6:30 am) and then set a delayed start of 3 hours (in summer) or 6 hours. I try to get my wife to do something similar with the washing machine – with modest success. She washes and dries whenever she feels like it.
But with such small things you can still steer consumption a bit.
Do you have the possibility to program the heat pump so that it starts heating/hot water preparation, e.g., at 10:00 and 14:00 and turns down in the evening hours? No idea if this is possible.
