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 significant financial and CO2 savings for the stadium while keeping the pitch in the high-quality condition needed. Every year more than 1.500 stadiums could save:

●Up to 2.250 MWh

●Up to 750 ton CO2

●Up to € 225.000 (electricity only)

●Up to 750 man hours

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.
