TOPSUN has obtained the first TUV certification which ranged from 355wp to 430wp in 1W increments by TUV Rheinland on 26th June 2010.

It is the best module which is using 6 inch solar cell.

Our 400wp modules have passed the 5,400pa of mechanical load test. It means that we have solved the structural anxiety on large size modules.

As our 400wp modules have many strong points, the modules will play a leading role in the world.

The 400wp modules have great advantages on over than 1MW solar power stations.

During the solar station construction, our 400Wp modules are bring about groundbreaking saves than exising 225wp modules. Our module needs smaller solar site dimension, shorter construction periods, smaller concrete consumption, smaller quantity of fixing clips in total. So we can reduce the total construction costs very much.

Our PV modules are great present for the PV installers.

We will do our best for ceaseless growth in the prospective photovoltaic field.
