Frameless Modules

摘要

Frameless PV modules, such as Lumos Solar's LSX series and Trina Solar's PDG5s, are gaining traction beyond traditional thin-film options. Trina Solar's frameless modules (and Silicon Energy's Cascade series, which are only framed on two sides) have a standard sheet of glass on top of the cells but instead of a plastic back-sheet, use another layer of glass on the back. Double-glass construction earns these PV modules a Class A fire rating, and they may be the only modules suitable for installation in certain jurisdictions (for example, in urban-wildlife edge zones in California).
