Among the renewable energy sources that has been gaining popularity as a eco-friendly alternative, solar power has been at the forefront of the international movement towards clean energy. While demands for photovoltaic modules are expected to increase dramatically as more countries begin to enforce environmental regulations and turn to cleaner energy sources, the safety evaluation aspect of the technology is still in its developmental stages.

The safety standards IEC 61730-1, IEC 61730-2 and UL1703 require that the photovoltaic modules as well as materials used in their construction be appropriately tested.

In response to this recent trend and to provide reliable testing data for the standards that are expected to become the global standard for photovoltaic module testing, IEC 61730-1, IEC 61730-2 and UL 1703, we have received a certification from the A2LA (American Association for Laboratory Accreditation). As A2LA is a US certification body participating in ILAC's mutual authentication, its data are widely accepted throughout Europe and Asia in addition to the US.

With this, we are now able to provide internationally accepted and reliable test data specific to photovoltaic modules as well as our existing line of certified tests of general plastic material.
