ᐅ Daylighting the ground floor using a heliostat and fixed mirrors

Hello everyone,

I’m having trouble making progress with this topic. Apparently, there is only one provider in Germany (EnLiCos), and they charge over 10,000 euros. Every house is, of course, unique.
What I have found out so far is that the actuator which moves the mirror to follow the sun’s path originates from satellite technology...

Maybe someone here is familiar with this subject and can offer some advice. I would appreciate it.

Thank you very much, Alex

What kind of valley do you live in that you need something like this?
I only know of a few Alpine valleys where this is common. I would suggest looking for suppliers in Austria or Switzerland.

Hello, we are quite enclosed, and the living-dining area is on the ground floor. I would like to use a heliostat and fixed mirrors to bring more sunlight down...

Take a look at interferenz dot de. I have no idea about the price range. Stelio is also available, but probably even more expensive. I’ve also seen some DIY solutions. It seems to be a very niche market. For €10,000 (about $11,000), you could install a daylight lamp in a garden shed and run it for a long time. That way, you wouldn’t depend on the sun.

Hello,

I’ve called Interferenz. 30,000 euros (€). Not possible!
I will also call Stellio. Thanks for the tip!
Yes, the market is very limited. However, I could imagine that this will change in the future due to increasingly dense building developments.
I’m not familiar with such a strong daylight lamp yet.

To me, this looks like a typical residential building. I would suggest the more cost-effective option of having larger or additional windows. I don’t see the problem in the picture.
