Originally, Bosch Solar CIS Tech operated under the name Johanna Solar Technology GmbH. However, in November 2009, the Bosch Group became involved in both aleo solar and Johanna Solar.
At that time, Bosch acquired an around 60% stake of Johanna Solar and, with part of it, founded Bosch Solar CIS Tech GmbH. Also at that time, aleo held a 17% stake in Bosch Solar CIS Tech and Bosch owned a nearly 70% stake in aleo, which increased gradually.
Bosch Solar CIS Tech GmbH currently produces thin film photovoltaic modules in Germanys Brandenburg an der Havel, near Berlin.
Around a month ago, Bosch waived aleos repayment of a 25 million loan, in order to help ease the photovoltaic manufacturers financial situation. Shortly afterwards, aleo announced a sharp decline in revenues and an EBIT loss of 51.5 million in the first nine months of 2012.
