250 W – 270 W Poly-crystalline Solar Module

SEP 250W/255W/260W/265W/270W

  • Plus power tolerance to +3% to ensure the high reliability of power output
  • PV glass design improves oblique irradiance performance and enhances module yield in low-light and medium-angle-light condition
  • Junction box and by-pass diodes guarantee the modules free of overheating and “hot spot effect”
  • 100% EL test before and after lamination, providing higher quality assurance
  • Easy installation and minimal maintenance with compatibility to industry standard inverters and mounting systems
  • Modules certified by TÜV to withstand high level of wind and snow loads (2400 Pa / 5400 Pa), hailstone impact (25 mm at 23 m/s), atmospheric impact (Salt-mist corrosion Test, Ammonia Resistance Test), potential induced degradation (PID) test and Carbon footprint assessment
  • Special PV Module Insurances by world leading insurance company guarantees the benefit to PV investors and PV module users

WARRANTY
