280W polycrystalline solar panels for home use

1.High conversion rate
2.High-transmission rate glass
3.TUV,UL,ICE,CE certificated

Anti-reflective solar glass

Nb solar modules use a textured cell surface and tempered glass for solar use only to reduce reflection of sunlight.An anti-reflective coating provides a uniform blue color and increases the absorption of light in all weather conditions.

Long service life

Nb solar modules can serve for at least 25 years,5 years warranty on material and workmanship and gurantee their output at 90% after 10 years and 80% after 25years.

Excellent construction

Nb solar modules have been encapsulated with the greatst care:they can resist corrosion caused by rain,water,gas.Their anti-shocking performance makes them resist hail and work under artrocious weather conditions where temperature changes quickly.

Real life examples

Nb solar modules have applied in many areas.Buiding roofs,photovoltaic power plants,telecommunication station,etc.And have been exported over the whole word where they enjoy an excellent reputation.
