Yes. It is obviously possible to contact an installer before the construction of your house to discuss and plan what is needed for the installation of DualSun panels. For us to put you in contact with the installer however, we prefer that the scope of the installation be very clear and the building permit already written up. Before that it is better to discuss the project directly with the architect or your design office.
Any construction project has of course its distinctive elements that can be surveyed. For an initial personalized estimate of your future home and the energy and economic benefits of a DualSun installation, we have put the free software tool MyDualSun at your disposal. Feel free to connect and use this first.
