The savings shown on this page are based on simulations and should not be interpreted as guaranteed savings. For the simulation we assume an annual household consumption of 5,000 kWh, an annual solar production of 5,000 kWh and a 10 kWh, 5 kW battery. The simulation is based on OMIE day-ahead prices and system and distribution costs for 2023. For the simulation we have used a standard 2.0TD 2023 consumption profile along with an estimated production profile. All savings shown are estimates, no rights can be derived from any information shown.
