No. In the case of a solar installation with a standard offer (CESI), the project study is free; it is carried out using the MyDualSun software platform.
With our solar project study you are assured a personalized answer with which you will be able to study the specifics of your solar project in detail. You’ll have all the key information in your hands to decide whether DualSun panels meet your energy needs and whether to proceed with their installation.
On the other hand, for a more complex solar project study (SSC, pool heating, multifamily housing, etc), the study is done on a case by case basis. You will be billed 100 € for it; and will be reimbursed if the project is then carried out.
