The economic potential of grid defection of energy prosumer households in Germany
The fast decline in solar photovoltaics (PV) prices has brought grid parity or near grid parity to household systems, with alternative energy sources generating power at a cost less than or equal to the price of the power from the electric grid in many countries. This price decline, together with a...
