The investors of this installation from Piaseczno decided to choose the Gold Package, available in Energynat Solutions offer. On the roof of the residents of a 170-meter house in Piaseczno, there is an installation of really high quality. Power plant with the capacity of 9.86 kW was built entirely on a heavy-duty Dutch Van der Valk structure, to which we attached Q-Cells G8 Full Black modules. The black panels, in a black frame, blended perfectly with the dark color of the building without disrupting the aesthetic of the building. Investors opted for the technology that will allow them to save on energy for electricity up to PLN 5500 per year. Return on investment projected in less than 7-8 years.
