First Solar PV Modules are designed for safe and reliable operation.

First Solar modules are subjected to extensive testing that replicates the environmental conditions modules will be exposed to over their 25+ year lifetime. Tests include long term "light soak" exposure to estimate the stability of energy output over the life of the module; the "hail ball" test to ensure modules can withstand golf-ball size hail pellets; and exposure to accelerated levels of heat and cold to ensure performance is not affected in extreme environmental conditions. Independent, third-party laboratories conduct testing and approve modules to recognized industry standards for safety and performance.

An ongoing global Production Reliability Monitoring program ensures that First Solar modules are continuously meeting or exceeding these safety and performance standards in all production locations. Once the modules reach the field, First Solar continues to test and monitor performance to ensure that they're operating as expected in all climates and weather conditions.

Key Product Design Features

• Front (Substrate) and Back (Cover) Glass
  Laminated glass sheets are heat-strengthened to withstand handling and thermally induced stresses, while avoiding breakage over the 25+ year module life.
• Semiconductor
  CdTe compound semiconductor material forms the active photovoltaic cells, which convert sunlight into electricity.
• Laminate Material
  Used to bond the cover glass to the substrate, sealing the photovoltaic device from the environment.
