Any remote consultations related to the installation and/or conversion of solar systems are provided by the company's specialists free of charge.
However, if you want the object to be inspected in person, giving answers already about the specific project, then this type of visit usually costs from 80 to 150 EUR* - depending on the location of the object and the degree of complexity of the project.
* In case of a successful transaction - the fee for the first consultation is returned to the client in full!
