Definitely yes! A photovoltaic system in combination with an energy storage device enables a faster amortization of the investment and makes you largely independent of changes in electricity prices, which is reflected in lower and stable monthly electricity bills. It is crucial that the output of the system is selected in such a way that self-consumption (use of the electricity produced at the place of generation) is maximized without significant surpluses arising. The energy storage in such a plant serves as an energy buffer that transports the energy from the production peaks (around noon) and later when the sun is leaning towards the west or completely sets.
