    About the blind current fine for solar panels

    When solar panels are installed, they will produce "real power" under sunny conditions. The load present in the installation will absorb this active power from the solar panels. The remaining generated active power is fed back to the electricity grid.

    However, many taxes also absorb "reactive power" in addition to actual power. These are called inductive or capacitive loads. A good example of this are electric motors. However, solar panels usually cannot generate reactive power. This means that this reactive power will still be supplied from the electricity grid.


    Since in this situation the active power of the loads is supplied from the solar panels and the reactive power of the loads is supplied from the electricity grid, the ratio between the absorbed active power and the absorbed reactive power on the electricity grid will be extremely disadvantageous. Depending on the agreements with the grid operator / energy supplier, a fine can often be charged on the reactive power consumed if this ratio is too low.

    In short: even when energy is saved by generating it yourself with solar panels, maximum cost savings cannot be achieved in many situations because additional blind current fines are charged.
