A heavy-duty anodized aluminum frame provides strength and convenient mounting access. Cells are laminated between high transmissivity, low-iron, 3mm tempered glass and sheet tedlar-polyester-tedlar (TPT) material by two sheets of ethylene Vinyl acetate (EVA). This protects against moisture penetrating into the module. Mono-Crystalline cells are up to 20% efficient and is said to have a service life of about 25 years.
