Sonnenglas® Eco Impact
Our Commitment to Climate Protection
Solar Energy for a Brighter Future
At Sonnenglas, we are redefining light by tapping into the endless energy source of the sun. Unlike traditional lamps or candles, our products can run entirely power-free and emission-free during use. By day, they harness solar energy and transform it into clean LED light by night. A great solution that requires no outlet.
However, it's not just our products that set new standards, it's also how they’re made. Our production facility in Johannesburg is mainly powered by solar energy, enabling us to consider our ecological footprint right from the manufacturing stage.
6th Generation High-Tech
The beating heart of our solar lineup is the , which powers every single one of our products. Its clever design harvests solar energy even under low light, turning it into a warm, welcoming glow when night falls.
How our Solar Light Helps Saving Resources?
The is more than just a light source, it powers all the products in the Sonnenglas solar ecosystem, from the classical to the and the . Cutting-edge battery technology allows for an impressive light duration of up to 100 hours per charge (depending on the model and brightness setting). This not only means you can enjoy prolonged warm lighting, but it also saves 100 hours of electricity and CO₂ emissions each time compared to traditional light sources.
Durable Battery Technology
Less frequent charging cycles extend lifespan, minimizing battery waste
Highly Efficient Solar Cells
Utilize solar energy even in low light, reducing grid reliance significantly.
Smart Energy Use
Auto-adjusting light output ensures minimum energy consumption and maximum battery longevity
Modular Structure
Swappable components enable easy repairs, extending product lifespan greatly
Flexible Design
Each SOMO seamlessly integrates in all Sonnenglas products for flexible usability
Modular System
Our design philosophy centers on modularity, so you don’t have to buy a whole new product if something breaks. For example, our consists of five separate components. Each of these parts can be easily replaced, ensuring that you never have to replace the entire product.
This approach significantly contributes to waste reduction. By opting to repair rather than replace, you actively minimize environmental impact and help extend the lifespan of our products even further. This modular approach makes repairs not only more affordable but also more accessible, saving you money while encouraging sustainable consumption.
Universal Applications
Way beyond a simple solar lantern, Sonnenglas is an adaptable, modular ecosystem built with intention from the very start.With the SOMO Solar Module, you can enjoy the flexibility of our entire product range. Whether you need a bedside lamp, garden lantern, flashlight, or table lamp - Sonnenglas has you covered.
The is universally versatile: use it in the while camping, in the garden with the , at dinner with the , or even on its own as a handy pocket light for on-the-go use. Our solar system offers countless flexible application possibilities, seamlessly integrated into the design, so you can bring light precisely where you need it, without having to purchase a different product for each use. At Sonnenglas, everything is considered from the very beginning. Welcome to the solar system!
Eco-Friendly Production. Sustainability Throughout the Entire Process.
From raw materials all the way to the final light, every production step at Sonnenglas is designed with respect for our planet in mind.
Photovoltaic System
Making solar products takes energy too. Which is why our production plant in Johannesburg relies on its very own solar system. With 105 PV rooftop panels outputting 40 kW, most of what we build is powered straight by the sun.
Sustainable Materials
Wherever possible, we use recycled and sustainable materials, from the raw materials to the packaging of our products. For example, the glasses of our are made from recycled glass, significantly reducing waste. The glass for our is also 100% recycled and is melted down in a furnace powered by used cooking oil – saving valuable natural resources and avoiding fossil fuel
Fair Solder
For all our soldering, we rely strictly on transparently sourced tin: either obtained from verified and certified producers in emerging nations or derived from pure secondary raw materials of European origin.
Global Components, Local Responsibility
It’s impossible to manufacture an electronic product entirely in one location. Our production in South Africa requires importing some electronic components: the batteries for instance are from China. Despite the international nature of these components, we ensure through our Code of Conduct that our supply chain meets strict social and environmental standards.
International Awards. The Multi-Award-Winning Solar Light.
By consistently combining outstanding design with our values, our products have been honored with over 20 international awards, including prestigious accolades such as the Big See, Good Design, iF Design, Red Dot, and Social Products Award.
The First Solar Light with the "Blue Angel"
Sonnenglas proudly bears the "" eco-label – the first solar lamp ever to receive this demanding certification. This esteemed label, issued by the German Federal Ministry for the Environment (BMUV), represents the highest environmental friendliness and confirms the high sustainability standards met by our products. But there's more: since 2019, we have also been recognized as a supplier by the 'World Shops Association' and sind 2026 we are an official member of the World Fair Trade Organization (WFTO).
