Average Italian family can save $18,170 over 20 years with home solar and battery

The Italian business of German battery maker Senec has calculated how much an average Italian family could save on electricity costs by installing a home solar-plus-storage system.

“A family with average electricity consumption of 3,600 kWh per year and an energy cost of €0.35/kWh could end up spending over €30,615 in 20 years, considering an annual increase of 2% in [electricity] tariffs,” said Senec, which compared that outlay to the total, 20-year energy expense of a home with a 3.9 kWp solar array and an energy storage system.

In the latter case, Senec said, “the overall cost of energy would drop to €13,113, considering the cost of the [solar and energy storage] system, with a 50% tax deduction, and the remaining electricity bills. This translates into a net saving of €17,502 in 20 years.”
