Suntech's technology yields improvements to BSF structure and anti-reflective coating to increase conversion efficiency.

The panel provides more field power output through an advanced cell texturing and isolation process, which improves low irradiance performance.

Unique design on drainage holes and rigid construction prevents frame from deforming or breaking due to freezing weather and other forces.

Suntech was named Frost and Sullivan's 2008 Solar Energy Development Company of the Year
