What we believe in

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.

What we do

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.


What excites us

Eternal Sun Group believes in the potential of solar and the potential of technical students, therefore we sponsor the two solar related raceteams of the Delft University of Technology: The Nuon Solar Team, famous for winning the World Solar Challenge in Australia 5 times and the Delft University of Technology Solar Boat Team which is competing in the Solar Boat World Cup and the Solar1 Monte Carlo Cup (Monaco) this year. Part of this sponsorship is helping them to improve the performance of their solar racing equipment with advanced solar simulation equipment and specialized testing services. The subsequent aim is showing the world the possibilities of advanced technology and solar power and inspiring people to strive for a more sustainable future.
