HPS Home Power Solutions has introduced the new generation of picea, its solar-hydrogen home storage system.
With picea 2, the company has achieved what it describes as “a significant technological leap forward” with a system containing 15kW capacity, doubling the output power.
It can provide buildings with a continuous supply of CO2-free solar power from their own rooftops, even in winter. It was developed in the Berlin-Niederschöneweide R&D facility.
The system is capable of satisfying elevated demands, such as those for electric vehicles or heat pumps, the company claims.
In the event of an external power interruption, the reinforced backup power supply ensures the uninterrupted provision of electricity to critical household appliances and it provides long-term storage capacity of up to 1,500kWh.
The new generation also provides a significantly increased maximum connection capacity for photovoltaic systems. As a result, picea 2 aligns with a discernible market trend toward larger photovoltaic installations.
Thanks to its new power electronics, picea 2 exhibits higher efficiency and enables even greater levels of self-sufficiency. Furthermore, picea 2 features status indicators that offer transparency on crucial system and storage conditions.
The interior energy unit, in comparison to its predecessor, is now easier to install, being over 70% lighter and with a smaller footprint.
picea 2 can now be installed in low basements or other suitable locations within the home. This development creates a crucial foundation for collaboration with installation companies by HPS.
Zeyad Abul-Ella, Founder and CEO of HPS, said today marks a milestone in the nine-year-old company’s relatively short history.
He said, “In both the national and international contexts, we offer an energy storage solution that continues to stand out on a technological level. Our growth strategy entails a rapid market reach in collaboration with installation companies. With all the enhancements, especially those aimed at streamlining the installation process, we have created vital prerequisites for long-term partnerships.
“The energy policy relevance of our new picea, particularly in conjunction with electric vehicles, heat pumps, and grid expansion, is exceptionally high.”
The electrification of private households in Germany, driven by the adoption of technologies like heat pumps and electric vehicles, is expected to triple the country’s electricity demand.
Meeting this increased demand requires a greater number of year-round energy storage solutions to ensure a continuous and reliable power supply, while preventing the curtailment of surplus renewable energy during peak periods.
Year-round energy storage systems installed within buildings are particularly well-suited for this purpose, as each self-consumed kilowatt-hour that does not feed into the grid minimises the need for grid expansion. picea converts surplus solar energy from a building into hydrogen during the summer, enabling efficient and long-term energy storage on a large scale.
