I'm not usually a fan of these wooden houses, but overall I really like both of them, and they especially suit the surroundings!

Thank you for the feedback – blending in with the surroundings was one of our goals. Once the garden is landscaped in a few years and the wood has weathered to a gray tone, a good harmony between the house and its environment will develop.

@hampshire: What is the reason for not installing the solar roof tiles over the entire roof? And what is the total kWp capacity you have installed now?

@hampshire: What is the reason you didn’t install the solar roof tiles on the entire roof? And how many kWp have you installed in total now?

The background is as follows:
- Our carbon reduction goal: The house should produce more clean energy than it consumes. The system is generously sized for this.
- We wanted to stay below 10 kWp to avoid paying the self-consumption energy surcharge – installed capacity is 9.99 kWp.
- A photovoltaic roof tile is more expensive than a regular roof tile.
- The difference is not visible from the street view, only up close like in the photo.
- We can easily expand to up to 27 kWp later on by simply replacing and connecting more tiles; the wiring has already been planned accordingly.

Thank you for the explanation. I had already suspected that you reached the 10kWp limit. And it’s also understandable that photovoltaic roof tiles are more expensive.

Do you know approximately how high your electricity consumption will be? The common recommendation from photovoltaic forums is always to maximize capacity, as long as it makes sense in terms of solar irradiation.

Which photovoltaic roof tile are you using?

Maximum system sizing made sense when feed-in tariffs were higher than the electricity purchase price. Those times have been over for a few years now. The energy surcharge payable makes maximum sizing even less attractive for private households. Economically, it is more sensible to optimize the system size for self-consumption and to complement it with an energy storage system. From an environmental perspective, it is worth considering compensating winter consumption with corresponding feed-in during summer. However, this negatively affects economic viability (as in our case).

Our anticipated electricity demand is an "unknown" since we will change some lifestyle habits with the move and currently have no experience data. Additionally, we have already factored in that we will rely on electric mobility for local transport in the near future.

The photovoltaic tiles are from Autarq. Ours are based on the Creaton Domino flat tile system. In addition, there is a hybrid inverter from Kostal, a large BYD battery box, and the connection to the heat pump hot water storage tank.
