Floor plan tube house L-shape triangular plot including oak tree

Great great great... as a child I also had a tree in front of the window... and I don't remember much, but I do remember the branches tapping on the window and the rustling of leaves in the wind. Ah. Yes, you might need light - but with the current summers, for me the advantage of shade outweighs it

Are there any news? Photos would of course be a dream.

Yes, although progress is rather slow. Interior plastering and screed are done. Tomorrow we will finally continue with the exterior facade. I will provide photos later.

A quick question for the tech experts here...

We switched from gas/solar to a heat pump during construction. It only really makes sense with a photovoltaic system. However, we currently have no budget for that. But before all the holes, slots, shafts, and whatever else are closed, I wanted to at least run the cable for it to the roof. Is there a standard cable for that, or does the cable size vary depending on the size of the photovoltaic system? Speaking of size: What output should the system have for an 8 kW heat pump and a wallbox in the garage?

Typically, cables with a cross-section of 4qmm are used for photovoltaic systems. The system should either be in the size range up to 9.99 kW or rather 12 or preferably 13 kW or more. The reasons can be found everywhere (Erneuerbare-Energien-Gesetz Umlage). Especially for an electric car, the system can hardly be too large, since in winter significantly less yield comes from the roof anyway. It is best to obtain a few offers in advance and have the preparations carried out by the electrician.

6mm² is standard, quantity depending on [Strings], [Dachflächen] etc.
