Dear friends and partners,

We are proud to share another important step on our journey towards a greener and more sustainable future.

Driven by our strong commitment to not only develop environmentally friendly products, but also to ensure that our manufacturing processes are in line with these values, we have made significant investments in renewable energy.

Following the successful deployment of solar parks with a total capacity of 9 MWp, we have now invested in the installation of the largest single solar storage battery in the region - with a capacity of 3.7 MWh.

This milestone is a key part of our mission to reduce emissions, lower our carbon footprint and make a significant contribution to the transition to clean energy.

Because investing in the future - a green future - is the smartest investment any business can and should make.
