Dear interested customers,
Up to this point, we have always tried to find you a suitable specialist company in your area. Due to the current high demand, many of our specialist companies have hardly any free capacity. Therefore, a mediation on the part of Wagner Solar can not take place at the moment. We ask for your understanding.
