Hello
we are planning a new semi-detached house.
We want to install a photovoltaic system later on.
We will get the right half shown in the photo. Orientation is southwest.
The photovoltaic system will of course be installed on the southwest side facing the garden.
The black area is the 3x5 m (10x16 ft) terrace, which will later be covered with a fixed terrace roof measuring 4 m (13 ft) deep and 5.5 m (18 ft) wide.
My question is whether it will still be possible to install a photovoltaic system on the roof once the fixed terrace roof is there?
If the terrace roof is on the southwest side in the garden, it will no longer be possible to set up scaffolding.
For maintenance or in case of problems, access to the photovoltaic system will be necessary later on (is access without scaffolding not possible?)
Or can the photovoltaic system be installed without scaffolding?
The house will have a gable roof and 2.5 full stories.

We only installed the battery because of the requirements for KfW 40+. Also, no more than 14.4 kW (19.3 hp) of photovoltaic panels fit on the roof. I didn’t optimize much but rather followed a few ‘brute-force’ approaches: lowering the heat pump temperature by 2°C (3.6°F) at night, setting the hot water to run only during the day via a timer program, and connecting the washing machine and dishwasher to the hot water supply—that’s about it. Whenever possible, we try to run the washing machine and dishwasher when there is surplus photovoltaic energy, but that is more out of personal challenge than practical importance.

Full cycles are calculated from charging energy/storage capacity, or do I have to read them off?In my opinion, it’s the amount of discharge, so losses are already deducted. That’s how I calculated my value.
Who has recently received offers? I have quotes for 10 kW including installation ranging between 16,000 and 20,000 euros. That is definitely too expensive, and no, these prices do not include storage. I hope that the form in that one forum will be available again soon.
If the prices still don't make sense, I will install it myself on the roof.

But the offer from the forum was quite good when it finally arrived. It’s definitely worth asking there.
If you mean the one with the form.

The question is whether and when prices will become cheaper again. My electrician just mentioned that although he has no trouble getting the panels, he cannot obtain the aluminum profiles. He has to buy them at a high cost through indirect channels.
If the first cities, states, or even the federal government enforce mandatory solar installation, I expect prices to rise during this legislative period.
It probably only helps to compare more or to do the installation yourself.
