Sonnen launches trade-in program for old solar battery storage systems regardless of condition or manufacturer
Detail:
The initiative by the Allgäu-based company targets owners of photovoltaic storage systems installed before the end of 2020. The value of the trade-in bonus depends on the capacity of the new Sonnen battery. Sonnen describes the campaign as a “targeted growth initiative in a new market segment.”
