At Second Sun we use green energy for better pitches. We have developed an innovative and award-winning reflector system for sports stadiums to re-direct sunlight to areas where the grass needs growth.


 Sustainable. Cost-Efficient. Automated. 

 Solution for Natural Grass Growth 



Second Sun provides


Leverage a full spectrum of sunlight reflected from the innovative system and reduce your CO2 footprint significantly


No running costs associated and a quick return on investment from energy- and manual labour savings


The system is designed and built with advanced automation and an intelligent control system

High quality pitch

Remarkably increase the amount of sunlight projected to the pitch - even in shaded areas

Second Sun Case Example

Yearly electricity savings for a medium-sized stadium:

500.000 kWh*

* Based on Second Sun simulation software, historical weather data, existing 1000W light rigs available in the stadium and a target of 12 DLI per day - the actual savings will vary based on geographical location, orientation, height and local weather conditions but 500.000 kWh is a conservative estimation applicable for most stadiums across Europe with existing artificial light rigs

... which equals CO2 savings of:

150 tonnes of CO2*

* Based on data CO2 emission intensity in Europe (

Daily electricity savings in average weather conditions and sunny weather conditions for a medium-sized stadium*:

* As it is seen the kWh savings are lower on Sunny days compared to average days for some months. The reason is that for sunny days the need for additional PAR-light is lower and thus, the kWh savings are also lower

Second Sun in Brøndby IF


Chris Hague

Groundsman, Brøndby IF

"Innovation and new technologies are part of Brøndby IF on and off the field. That's why we also want to take new steps to try to optimize the conditions for the grass," says Chris Hague, groundsman at Brøndby Stadium.

"There are parts of the southern end that need more sunlight than it can get naturally. No alternative is better for grass to grow than sunlight and the right temperatures, and with Second Sun we try to provide that to the whole pitch. If it works, as we hope, it will be a win for the pitch - and for the environment."

Sunlight Simulation

With our advanced Sunlight Simulation tool, we can simulate the yearly sunlight for any stadium in the world - Please reach out to us if you would like a free Sunlight Simulation for your stadium to better understand how your pitch is affected throughout the year.
