The amount of CO2 savings depends on various factors, such as the size of the PV system, its location, and the technology used. In Germany, an average photovoltaic system with a capacity of 5 kWp can save about 3,000 kg of CO2 per year by reducing the electricity drawn from the public grid. This is roughly equivalent to the emissions of a car with a gasoline consumption of 8 liters per 100 kilometers, traveling a distance of 15,000 kilometers per year.
