Bosch Solar Energy

What Bosch Solar Energy does

Bosch Solar Energy operates as Bosch Solar Services GmbH, a wholly-owned subsidiary of Robert Bosch GmbH headquartered in Arnstadt, Germany. The company provides after-sales service, warranty support, technical maintenance, repair, and operational management for solar PV products, including crystalline and thin-film modules, string and central inverters, inverter stations (BPT-IS and VIS series), and hybrid storage systems (BPT-S 5 Hybrid). It supports an installed base of legacy Bosch and aleo-branded solar equipment manufactured prior to 2014 through direct service provision and a network of authorized international service partners across six countries.

The company's technology stack centers on PV plant monitoring and management software, including the e.Web internet portal for performance analytics and alarm management, the e.UserApp mobile monitoring application, e.Designer system sizing software, and the BPT-M Touch plant monitoring system. It maintains an in-house laboratory certified for solar module testing per IEC/DIN EN 61215 standards, including visual inspection, power measurement, insulation testing, temperature cycling, damp heat testing, electroluminescence imaging, thermography, and PID testing. The subsidiary Pollux Solar-Service GmbH extends service reach to private households, municipalities, and industrial customers.

Bosch Solar Services generates revenue primarily through professional service contracts, maintenance agreements, warranty claim processing, and managed services for technical and commercial operation of solar power plants. The company is certified under DIN EN ISO 9001:2015 and DIN ISO 45001:2018 (valid 07.08.2023 to 04.08.2026). Following the discontinuation of thin-film module production in April 2011 and the transfer of crystalline module manufacturing to aleo solar AG ending May 2014, the entity has transitioned from a solar manufacturer to a service-focused operation servicing the legacy installed base.
