How much does solar battery storage cost in Switzerland?
“A battery storage system installed by I.ON starts at CHF 6,500 for 10 kWh (BYD Battery-Box). A Huawei Luna 2000 or a Fronius Reserva of equivalent capacity ranges from CHF 7,000 to CHF 9,000, installation included. The price depends on capacity, brand and compatibility with your existing inverter.”

“Without a battery, a household self-consumes about 30% of its solar production. With a battery, that figure rises to 70–80%. For an 8 kWp installation in Western Switzerland, the extra saving is CHF 600 to 900 per year. The payback period of a battery is 8 to 12 years depending on your supplier's electricity rate.”

“For a 4–5 room house consuming 4,000 to 5,500 kWh per year, a 10 kWh battery is recommended. It covers evening and night consumption. For a house with a heat pump or an EV charger, scale up to 13–15 kWh. I.ON sizes the battery based on your actual consumption curve (12-month meter reading).”
