Why do Chinese panels have a bad reputation?
The bad reputation dates back to the early 2010s — when low-quality no-name products flooded the market. These modules genuinely had quality problems: faster degradation, weak warranties, poor customer service.
Since then, the industry has fundamentally changed. The major Chinese manufacturers — JinkoSolar, LONGi, Trina Solar, JA Solar, Canadian Solar — have invested billions in research and development. Today they are at least on par with European manufacturers in terms of efficiency, reliability and warranty duration.
The difference is no longer between "Chinese" and "European" — but between Tier-1 manufacturers and no-name products.

is the decisive quality criterion
Tier-1
What does Tier-1 mean — and why is it more important than the origin?
The Bloomberg Tier-1 status is the most important quality criterion for solar panels. To be recognised as a Tier-1 manufacturer, a company must: have delivered modules for at least 6 bank-financed projects, be rated as a reliable supplier by independent banks, meet proven production and quality control standards, and be financially stable enough to honour warranties long-term.
Tier-1 manufacturers from China: JinkoSolar, LONGi, Trina Solar, JA Solar, Canadian Solar, Risen Energy.
Tier-1 manufacturers from Europe: Meyer Burger (CH/DE), REC Group (NO), Luxor Solar (DE), SoliTek (LT).
Conclusion: A Tier-1 module from China is more reliable than a no-name module from Europe.
Direct comparison: Chinese vs. European
Efficiency: quality Chinese and European modules both achieve high values.
Lifetime: quality modules are typically designed for 25 to 30 years.
Warranty handling: Chinese ⚠️ often via Swiss importer | European ✅ direct European contact.
Hail protection Switzerland: Chinese ⚠️ varies by model | European ✅ often better certified.
Environmental footprint: Chinese ❌ longer transport | European ✅ shorter transport.
The major Chinese manufacturers
LONGi — world market leader in monocrystalline: The Hi-MO Series is one of the best-selling modules in Switzerland.

Who benefits from European panels?
If hail protection is a priority: In hail-prone areas, panels with HW4 or HW5 hail certification are recommended. Meyer Burger and Luxor Solar excel here.
If environmental footprint matters: Shorter transport routes, European production standards, better recycling infrastructure.
If Swiss quality is a selling point: Meyer Burger from Switzerland has emotional value for many homeowners.
Who should choose Chinese Tier-1 panels?
If the installer has experience with the manufacturer: A local installer who has been working with JinkoSolar or Trina Solar for years knows the products, the installation and the warranty process.
No-name modules from China — the real risk
The real risk factor is not "Chinese" in general — but unknown manufacturers without Tier-1 status. Warning signs:
- ⚠️ No Bloomberg Tier-1 status
- ⚠️ No PVEL certification
- ⚠️ Performance warranty under 80% after 25 years
- ⚠️ No European service partner
- ⚠️ Price significantly below market average
Ask your installer explicitly about the manufacturer and Tier-1 status of the panels. A reputable installer does not install unknown no-name products.

- ✅ Performance warranty of at least 80% after 25 years
