The Solvatten Portable Solar Water Heater is a revolutionary solution designed to provide safe and clean drinking water in off-grid households and communities that lack access to electricity or clean water sources. This innovative device harnesses the power of the sun to purify water, making it safe for consumption and other uses.

Constructed from UV-transparent plastic, the Solvatten device is foldable and portable, making it easy to transport and use in various settings. When exposed to sunlight, the device utilizes a combination of UV radiation and heat to disinfect water within 2–6 hours, meeting the safety standards set by the World Health Organization (WHO). The built-in fabric filter ensures that the water is free from impurities, while the LED indicator signals when the water is safe to drink.

In addition to purifying water, the Solvatten device also heats water up to 75 °C, making it suitable for cooking and hygiene purposes. By eliminating the need for chemicals or electricity, the device offers a sustainable and eco-friendly solution for water purification.

With a lifespan of 7–10 years and the capacity to treat up to 100,000 liters of water per unit, the Solvatten Portable Solar Water Heater is a cost-effective and long-lasting solution for communities in need. By reducing fuel costs, preventing deforestation caused by charcoal or firewood use, and improving health outcomes, the device has a positive impact on both the environment and the well-being of individuals.

Moreover, the implementation of the Solvatten device in refugee camps, urban slums, and rural communities supports climate adaptation efforts, Water, Sanitation, and Hygiene (WASH) initiatives, and gender empowerment agendas. Distributed through NGOs, UN partners, governments, and corporate donors, the portable heater plays a crucial role in providing access to clean water and improving the quality of life for vulnerable populations.
