How the sustainable Second Sun System works

The Second Sun System provides the necessary Photosynthetic Active Radiation (PAR) to the pitch, in an innovative and sustainable way.

About the system

Second Sun has developed a sustainable system for grass growth based on innovative and intelligent mirrors that can automatically redirect the natural sunlight onto any area of the pitch inside a sports stadium. This will provide the necessary Photosynthetic Active Radiation (PAR) light to promote the photosynthesis inside the grass plant.

Financial and environmental savings

As the Second Sun System provides the much-needed PAR-light to the areas of the pitch in need, the need for supplementary artificial growth lightning will be significantly reduced or completely eliminated. This ultimately creates huge financial and CO2 savings for the stadium while keeping the pitch in the high-quality condition needed.

Installation

The Second Sun System will be installed in the existing structure of the stadium and will automatically deploy and retract from underneath the roof when needed and project the sunlight onto the desired areas of the pitch. In contrast to artificial light rigs, there will be no hassle for the groundsman team to neither transport the system in and out of the stadium nor storing it when not in use.

No interference with other activities inside the stadium

If there is no need for the Second Sun System or there is an event inside the stadium, the mirrors will automatically fold up underneath the roof ensuring no interference with the activity inside the stadium nor the spectators view from the stands.
