Helvios Sàrl bridges premium solar technology from China's leading manufacturers directly to Switzerland and Europe — with Swiss precision, reliability, and accountability at every step.
Founded in Vaud, Helvios Sàrl was built on a simple conviction: Switzerland deserves direct access to the world's best solar technology, without unnecessary intermediaries and without compromising on quality.

We offer a full range of services around solar technology — from procurement and logistics to consulting and project support.
Direct sourcing of solar panels, inverters, batteries, and balance-of-system components from certified Chinese manufacturers.
End-to-end import management including freight, Swiss customs clearance, VAT handling, and last-mile delivery coordination.
Product selection guidance, technical specifications, and compatibility assessment for your specific project requirements.
Factory assessment and due diligence for clients seeking to establish their own direct relationships with Chinese manufacturers.
Bulk procurement and phased delivery planning for large-scale solar installations and commercial energy projects in Switzerland.
Warranty management, replacement coordination, and ongoing supplier liaison for products sourced through Helvios.
From generation to storage — we source the full spectrum of solar technology components from leading manufacturers.
Monocrystalline, polycrystalline, and bifacial modules from Tier-1 manufacturers. Commercial and residential grades available.
Grid-tied, off-grid, and hybrid inverters. Single-phase and three-phase configurations with Swiss grid compatibility.
LFP and NMC lithium battery packs for residential and commercial energy storage. BMS-integrated, certified systems.
Roof, ground, and façade mounting solutions. Aluminum and steel structures engineered for Swiss weather conditions.
AC and DC charging stations for electric vehicles, compatible with Swiss and European standards.
Smart monitoring systems, energy management units, and remote diagnostics platforms for solar installations.
Working with a Swiss-based solar sourcing company means full legal protection, local expertise, and the trust that comes with accountability.
All contracts are Swiss law governed. You deal with a local company, not a foreign supplier you can't easily reach.
We only work with manufacturers who hold IEC, TÜV, or equivalent certifications. No surprises at customs.
Factory-direct relationships mean pricing that intermediary-heavy channels simply cannot match.
We operate in French, English, and Mandarin — removing communication barriers at every stage.
All products sourced through Helvios are required to meet Swiss and European import standards before any order is placed.
Whether you're a solar installer, developer, or business exploring energy independence — we'd like to hear from you.
