Trina Solar’s 310 Watt solar panel is composed of 120 1/2 mono-crystalline half-cells that help prevent energy loss. Featuring the use of a new cell string layout and split J-box location, these panels are protected from energy loss caused by shading. An Integrated Light Redirecting Film (LRF) is applied to non-active areas of the solar panel to redirect potentially lost light back onto the active solar cells.
