HPS develops and produces systems for storing and using solar energy in single- and two-family homes. HPS stands for safety, independence and sustainability in decentralized energy supply. The first system from HPS, Picea, combines energy storage, heating and indoor ventilation in one compact system. Thanks to its high-performance energy management system, Picea is able to meet the complete electrical energy needs of a family home. HPS is based in Berlin.
We want our customers to decide where their energy comes from. We stand for sustainability and transparency and have developed a solution enabling our customers to enjoy exactly that. With us, owners of family homes are able to produce and store their energy locally, in order to meet their needs. This not only conserves resources but also reduces greenhouse gases and helps slow down climate change. By using all by-products of the process adequately, we harness every sunbeam with maximum efficiency.
HPS solutions support the expansion of renewable energies.
As part of the global energy community, we are convinced that the cross-linking of our solutions to larger energy storage networks will create a building block for the success of the renewable energy revolution.
Experienced. Passionate. Enthusiastic. These characteristics describe our team. We strive to change the world with our work.
