Since 2002 the Spi-Sun Simulator has become the industry standard in module performance testing. It is now used by more than 30 standards testing and certification laboratories worldwide and is a staple in mass production lines around the globe.Solar is the most economical way to generate electricity in ‘sunbelt’ countries, and will be so all across the globe in the coming decades. Therefore, in energy investments, solar will be dominant. There are two large trends: First, a race down the experience curve drives efforts in R&D and module manufacturing to enable the maximum potential of solar modules and second: the downstream market is maturing. To cope with the margin pressure, knowledge on performance degradation will gain importance.We contribute to the development and growth of the solar industry by enabling the highest degree of measurement control and certainty by providing high-end solar testing advice, technology & services.
