Concentration of solar radiation using a heliostat and fixed mirror

As I interpret it, he wants sunlight on the terrace circled in blue.

There are enough windows. It is also fairly bright. But the sunlight is missing. Depending on the season, the sun is gone at 2:00 PM and only comes back behind the big house in the west again in August/September...

Then you are like millions of other people. Sorry, I cannot contribute anything else on the topic, as in 30 years of real estate experience I have neither seen such a system in any construction project (so far everyone has lived well with their situation and, if anything, is glad not to have too much sun INSIDE the house - the main thing is reasonably bright), nor have I ever known anyone who has even remotely thought about it. Even with a north-facing orientation, I would never come up with such an expensive exotic solution.

Thank you Nordanney. Please refrain from further contributions. There are too many complainers here and you are one of them. Don't get me wrong. But please just don't post anything else. It doesn't help.

I am in contact with EnLiCos. Current idea.
Mast. Foldable for maintenance of the heliostat.

As I understand it, you then need 2 stepper motors which are preferably remotely controllable by radio.

I can absolutely understand the desire and also find it interesting to see such solutions. As mentioned, I know it more from the Alpine region and partly from the Black Forest. I would do it too if it were necessary. This way, the outdoor area is also more usable. Please keep reporting. Would such a tall mast cause problems with the approval? I believe with EnLiCos the tracking runs fully automatically. So you set the point to be illuminated once and the tracking does the rest.

That would of course be the best solution with automatic tracking... Regarding approval... certainly not that easy... especially here in Baden Württemberg... It would certainly have to be classified as a flying component...
