Order your Twinsolar-System


A solar ventilation with an energy gain by Grammer Solar is simple and efficient in planning, installation and operation. Place your order for a system directly at our online shop and let it be installed by a local handyman. Experienced handymen can easily install a Twinsolar Compact on their own.

In case you should need professional support regarding construction or installation, you can gladly contact one of our partner companies in your area.
We would readily check up on your planning if you send us pictures and sketches of your house. For this reason, please order the item “Project consultation” in our online shop.

We will check your planning when you send us your pictures and sketches.
The more detailed your description of the object, mounting position and surrounding (shade) is, the more we can specify the installation.
As part of this consultation we also check wether the chosen collector size is suitable for the given mounting position. We will make proposals about alternatives and additional parts if necessary.
The consultation is made in all conscience, according to your information which you have sent us. We assume no liability.
