With a setup of HiBattery 4020 X and four 500W PV modules, the system generates about 2,378 kWh of solar energy per year (=5.96 kWh/day). Around 30% is used directly during the day, while the surplus is stored in the battery and used at night achieving up to 90% self-consumption. At an electricity price of €0.4/kWh, this results in an estimated annual saving of about €584,maximizing the value of every kWh generated.

**Actual results may vary based on usage patterns, regional tariffs, and dynamic pricing conditions.
