What Makes a Solar Panel the “Best”?

Efficiency & Output

High-efficiency panels generate more electricity per square meter—especially critical when roof space is limited. In 2025, panels with efficiency ratings starting at 21% are considered top-tier. Particularly noteworthy are bifacial N-type modules from brands like LONGi, TrinaSolar, and JinkoSolar, which perform exceptionally well in low-light conditions and rank among the most powerful panels on the market.

Thanks to their premium materials and proven technology, these modules also perform reliably in heat and partial shading—offering a clear edge over conventional polycrystalline alternatives. That’s why PVPro Solar exclusively uses N-type technology, which has earned top marks in multiple studies and is widely seen as the new standard for modern PV systems.

Types of Solar Panel Technologies

Solar modules differ in both material composition and cell technology:

By Material:

• Glass-Foil Modules: Traditional design with glass front and polymer backsheet. Lightweight and affordable, but with shorter lifespan.
• Glass-Glass Modules: Double-glass construction provides exceptional durability, fire resistance, and longevity—ideal for demanding environments.

By Cell Technology:

• P-type (Passivated Emitter Rear Contact): Standard, widely-used solution.
• N-type (e.g., Heterojunction or TOPCon):
  • Efficiency up to 22.3%
  • Minimal performance degradation over time
  • Excellent performance in heat and shading

Note: At PVPro Solar, we rely exclusively on N-type modules due to their superior efficiency and long-term economic value.

Warranty & Longevity

Key criteria to look for:

• Performance warranty of at least 25 years
• Product warranty of at least 15 years
• Successful testing according to TÜV standards (hail, salt mist, ammonia)

Brand Trust & Certifications

Choose reputable manufacturers with:

• Strong market presence in Germany
• TÜV and IEC certifications
• Verified sustainability across the supply chain

Our product selection is based on extensive evaluation and market research. The modules we offer are produced in leading factories, pass rigorous testing, and demonstrate high reliability. Anyone investing in solar today should opt for proven providers that combine technological excellence with environmental responsibility—for a sustainable and future-proof energy supply.
