Sonnen is launching what it claims is the first German battery storage exchange program. The company is offering households that installed a photovoltaic storage system before December 31, 2020, the opportunity to replace their old systems with a new Sonnen battery – regardless of the condition or manufacturer of the existing unit.
As part of this initiative, Sonnen is introducing a trade-in bonus modeled on the car scrappage scheme. Households can receive a credit of up to €2,800 ($3,223) towards the purchase of a new Sonnen storage system. The minimum bonus is €500 for a Sonnen battery with a capacity of 5.5 kWh, increasing in steps up to €2,800 for systems with a capacity of 33 kWh.
