This 9.8kW system consists of 32 x AEG Monocrystalline panels of 305W, and a SolarEdge 10kVa, 3-phase inverter with Optimizers.

Such a system produces about 16300kWh per year, yielding annual savings of €3500.

The panels are placed into three groups, each one operating under difference parameters (slope of the frame in relation to the ground, angle of incident sunlight on the surface of the panel) and therefore have a difference production. The SolarEdge inverter offers the option of connecting Power Optimizers to each panel. This technology allows each panel to operate independently, without being affected by the production of the other panels of the same grouping, which is very helpful in cases of shading and multiple orientations where we have reduced or varied energy production. This method is therefore used in cases where shading exists, and where the layout of the roof does not allow the installation of the necessary panels limited to two directions.



The Net-Metering billing method is a mechanism that debits the amount of energy produced by the solar system and not used directly onto the household, for future use. For 1-phase households, the maximum size allowed to be installed is 4.16 kW, whereas for 3-phase households this limit is 10 kW.
