Solar Power Plant International GmbH (SPPI)sppi logo

  • SPPI-GmbH was founded in September 2020 by the companies SET Software Engineering Tschürtz GmbH, Mainstream Consulting GmbH, RG-Sonnenstrom GMBH and Pindt & Partner Slovakia, k.s.



Our Vision and Approach

  • Solar Power Plant International GmbH (SPPI-GmbH) develops standalone solar power plants for the supply of energy in remote regions that either cannot be supplied by high voltage overhead grids or the investment in overhead lines would not deliver a positive return, even in the long run. Our solar power plants were developed as modular systems in order to be adapted as flexibly as possible to the local electricity demand and to the energy requirements at the respective location by connecting it to a local microgrid. This means that the systems are designed to be scalable. As a result, the performance output can be increased through expansion if necessary, without the basic or initial investment becoming obsolete. On the one hand, this provides the operator with investment security, and on the other hand, it is possible to react quickly to increasing energy demand.

  • Providing cheap autonomous energy supply for small communities in remote regions by renewable energy. We want to assist in enhancing the living conditions and support a sustainable economic and social development in the the region
