Sustainable by Design
Every decision we make is guided by our responsibility to people and planet. Solar power meets fair trade in a product that lights the way to a better future.
Light That Leaves No Footprint
Sustainability isn't just a buzzword for us—it's the foundation of everything we do. From the moment we conceived Sonnenglas, we asked ourselves: how can we create beautiful light without harming the planet?
The answer was simple: harness the power of the sun. Every Sonnenglas captures free, clean energy during the day and releases it as warm, ambient light at night. No batteries to dispose of, no electricity costs, no carbon emissions. Just pure, sustainable illumination.
Numbers That Matter
Our commitment to sustainability creates measurable positive change for people and planet.
Three Pillars of Sustainability
Our sustainability strategy rests on three interconnected pillars that guide every decision we make.
Clean Solar Energy
Every Sonnenglas is powered entirely by the sun. Our advanced photovoltaic cells capture daylight and store it in high-quality batteries that last for years.
- Zero electricity consumption during operation
- High-efficiency solar cells for maximum energy capture
- Rechargeable batteries rated for 1000+ charge cycles
Fair Trade & Social Impact
We believe sustainability includes social responsibility. Every Sonnenglas creates fair-wage employment and supports communities in South Africa.
- Fair Trade certified production in Johannesburg
- 75+ skilled artisans earning living wages
- Community development programs and education support
Circular Design
We design for longevity and recyclability. Every component is chosen to minimize waste and maximize lifespan, with 95% of materials being recyclable.
- Durable borosilicate glass lasts for decades
- Modular design allows easy repair and battery replacement
- Packaging made from recycled and recyclable materials
Recognized for Sustainability
Our commitment to sustainability has been recognized with multiple prestigious awards and certifications.
"We don't just want to make sustainable products—we want to prove that business can be a force for good. Every Sonnenglas is evidence that profitability and purpose can coexist."
People at the Heart of Sustainability
True sustainability includes social responsibility. We create products that benefit both planet and people.
Our factory in Johannesburg isn't just a workplace—it's a community. Workers receive fair wages, skills training, and the opportunity to build better futures for their families.
