Panel poly YL-255P-29b 255W/60


  • High efficiency, multicrystalline silicon solar cells with high transmission and textured glass deliver a module efficiency of up to 15.9%, minimizing installation costs and maximizing the kWh output of your system per unit area.

  • Tight positive power tolerance of 0W to +5W ensures you receive modules at or above nameplate power and contributes to minimizing module mismatch losses leading to improved system yield.

  • Top ranking in the “TÜV Rheinland Energy Yield Test” and the “PHOTON Test” demonstrates high performance and annual energy production


  • Tests by independent laboratories prove that Yingli Solar modules:

    • Fully conform to certification and regulatory standards.

    • Withstand wind loads of up to 2.4kPa and snow loads of up to 5.4kPa, confirming mechanical stability.

    • Successfully endure ammonia and salt-mist exposure at the highest severity level, ensuring their performance in adverse conditions

  • Manufacturing facility certified by TÜV Rheinland to ISO 9001:2008, ISO 14001:2004 and BS OHSAS 18001:2007.


  • 10-year limited product warranty.

  • Limited power warranty: 10 years at 91.2% of the minimal rated power output, 25 years at 80.7% of the minimal rated power output.
