Since the introduction of the SunCarrier, a+f GmbH concentrates on the development, project planning, implementation and service of solar power plants. The a+f invented SunCarrier is the largest, toughest and most profitable open space tracking system for photovoltaic that continuously adjusts the surface of the modules to the current position of the sun. This ensures the optimum angle for capturing sunlight and an increased yield of up to 30% in comparison to motionless systems which are aligned to the south. Solely in the last 12 months more than 43 MWp have been installed with the SunCarrier. To meet the several requirements of different regions and customers, the a+f introduces at Intersolar 2009 two new one axis tracking systems to the market. At the one hand the new SunCarrier 4.0 which is especially designed for regions in Southern Europe with height limitation. On the other hand the SkyCarrier 8.0 for the equatorial areas will be launched. Depending on costumers wishes the single installed module arrays are variable scalable in their number.
