Hermetically Sealed for Reliability

The thin film photovoltaic material employed by Solyndra’s proprietary modules is copper indium gallium diselenide (CIGS). Historically, CIGS cells have been known to degrade because of their vulnerability to moisture. Solyndra's design employs a hermetic seal at the ends of each module — creating a gas-leak tight glass-to-metal seal. In addition to a 25-year power warranty, Solyndra's products have received UL 1703 certification for use in North America and IEC 61730, IEC 61646 certification for international use.
