Sunmit is a mountain tent with an integrated flexible, rollable solar panel that allows you to be selfsufficient at Everest Base Camp. Designed to withstand extreme weather conditions, it is lightweight and easy to transport.
Define the problem/need you are solving or addressing with your project. How does it address the Open Call criteria, such as environmental impact, social engagement, circularity, user experience, resource efficiency, and community-driven solutions?
The main issue this project aims to minimize is the use of kerosene and gas, the energy sources currently used in Himalayan camps, reducing both waste and harmful emissions. The project ensures fair working conditions for the Sherpa porters, who currently carry all equipment on their backs. It also improves conditions for Sherpa-Cookers, freeing them from inhaling smoke and fumes by replacing traditional fuels with clean energy. The product is manufactured in local textile workshops in Kathmandu (Nepal) using local labor, reusing nylon from abandoned tents—a common waste in high-altitude expeditions—while supporting the local economy.
Please describe your project, reflecting on the concept, inspiration, materials, technical aspects, methods and process(es).
Its ergonomic design allows the solar panel to tilt up to 36° to maximize energy efficiency. Is a modular system: multiple units can be connected to expand energy capacity according to the expedition’s needs. A single unit provides autonomy for two days, allowing the charging of 11 phones, 2 laptops, or powering 8 lights for 6 hours. The fabric is recycled nylon, recovered from abandoned mountain tents or other base camps. The structure uses fiberglass rods repurposed from old tent frames. The solar panel is flexible, monocrystalline, and has a 25-year lifespan, reused annually by expeditions. Built to withstand extreme weather conditions, it is lightweight, easy to transport, and simple to set up.
What do you think makes your project innovative compared to the existing efforts and ideas in the field it addresses?
There is currently no tent on the market with an integrated flexible solar panel. Existing flexible solar panels are sold as standalone units, designed for placement on vans, caravans, or boats, but not on tents. Our system also has a positive impact on Nepal’s economy, one of the poorest countries in the world, promoting sustainable tourism and supporting the well-being of local communities in high-altitude environments. Creating an electrical network through these modular tents provides organization and safety within the camp, offering shared power for all members. Additionally, it is a temporary, easy-to-assemble electrical installation that leaves no waste and does not disturb the natural environment, maintaining harmony with nature.
Does it impact or reflect young people need(s) and how?
Yes, it does. Many young Nepali Sherpas still depend on these physically demanding and poorly paid jobs for their future and their families’ livelihoods. Young Sherpas carry up to 40 kg on their backs for 15 days and risk their lives climbing Everest to ensure clients return safely. Our project aims to reduce this burden by providing clean energy solutions, improving working conditions, and offering safer, more sustainable opportunities for the younger generation.
