250W-280W Poly-crystalline Solar Panel

· Two decades of experience in manufacturing, the complete PV chain of silicon materials, ingot, wafer, solar glass, solar cell and module, and ISO90001 & ISO14001 certified factory, to ensure excellent raw materials and production control.

· Modules certified by TUV Rheinland (IEC61215, IEC 61730 standards) in the extreme conditions (temperature, load, impact) with good performance. Pass strict tests of solar modules including Salt-mist Corrosion Test, Fire Test, Ammonia Resistance Test, PID Test, Sand Abrasion Test and Carbon Footprint Assessment in TUV.

· The good weak light performance (morning, evening and cloudy day) has been tested and approved by professional third-party.

· Guarantee from 0 to +6W as power tolerance, customers can obtain 5.8% power more than conventional output.

· 100% EL test before and after lamination, and finished products EL test, providing higher quality assurance.
