In 2008, a collaboration in the field of photovoltaics for ground-mounted and rooftop systems was established, based on partnerships with international manufacturers. However, the radical restructuring of the Renewable Energy Act (EEG) in 2011 by the Ministry of Economic Affairs called the business model into question, leading to an initial suspension of activities.
In 2020, STP-Solartechnik-Partner GmbH was relaunched with a renewed focus on acquiring and operating its own photovoltaic systems on properties within the company’s portfolio.
From 2023 onwards, sales activities commenced, leveraging expertise gained from CIR systems (Commercial, Industrial & Residential). This experience led to the development of tenant electricity models specifically designed for owners of multi-family homes (MFH). These models incorporate insights from large-scale installations. Thanks to state-of-the-art inverters, individual tenants can now harness solar power independently.
Additionally, in collaboration with energy corporations, multi-site projects have been developed. These ensure that multiple locations of a company can be equipped with photovoltaic systems, all managed under a single energy provider as a contractual partner.
