Our commitment to your energy transition
Who are we ?
H2SE Tech SA, based in Sion in Valais, specializes in the design and implementation of solar power plants and battery energy storage systems.
Our company focuses on proven expertise across the entire value chain, from preliminary engineering to commissioning and operational optimization.
With over fifteen years of international experience, the team brings together engineers and designers capable of supporting a variety of projects, from standard photovoltaic plants to complex hybrid architectures integrating BESS.
This expertise also extends to the energy optimization of existing installations, taking into account grid constraints, performance analysis, and maximizing energy value.
The proprietary sizing tools developed in-house form a major methodological pillar.
They ensure precision, reliability, and long-term robustness, while allowing the implementation of technical architectures adapted to economic and operational requirements.
We support you across the entire value chain in configurations, with or without storage, including advanced hybridization for network operators.
The solutions are designed to improve flexibility, strengthen network stability, and ensure sustainable operation.
H2SE Tech SA is committed alongside its clients in Switzerland and around the world to building resilient and responsible energy infrastructures.

Reducing our Carbon Footprint
We are constantly seeking to improve logistical control on both international and local scales by prioritizing orders/purchases within the Pacific region. Our approach includes consolidating material transports to sites and promoting carpooling
Control of our Waste
We are involved in the selective processing of waste by increasing inspections and making regular visits to disposal sites. Our internal approach emphasizes the importance of sorting waste, reflecting our commitment to sustainability and responsible waste management.
Quality Charter
Our internal Quality Charter aims to establish a common methodology for photovoltaic installers to ensure compliance with quality standards in all aspects of advice, system sizing, and installation quality.
