Products and services

Solar Water Solutions can turn seawater, or any undrinkable water into drinking water with direct solar power. No more diesel generators or high electricity bills, no more transporting of water. Water in remote settings is now affordable, local, safe, and sustainable. 

The company solves the energy cost and transportation problems in the most efficient way: 

  • A conventional water desalination system (making clean water from sea or contaminated water) needs a lot of electricity which is expensive. In remote locations, such as islands, deserts, and rural areas, the most common source of energy is diesel generators. They have high fuel costs and high CO2 emissions. Solar energy doesn’t cost a penny. 
  • Water is costly to transport, and building pipeline network is expensive. With a decentralized solar powered system you can make your own clean water. 


Solar Water Solutions offers a comprehensive range of small- and mid-sized modular, solar-powered desalination systems designed to produce clean drinking water from both seawater and brackish sources, without relying on fossil fuels, grid power, or battery packs. The SolarRO series, powered by SWS’s patented reverse osmosis technology, delivers a sustainable solution to water scarcity with high efficiency, direct solar operation, automatic pressure control, and a simplified design, significantly reducing the complexity compared to traditional desalination systems. SWS’s systems are tailored to meet diverse needs: smaller units provide reliable water for private properties, while larger systems support entire rural communities.

The modular design is infinitely scalable by installing multiple units in parallel to required water needs with a single unit capable of producing up to 500,000 liters of clean quality water per day. This adaptability makes SWS’s solutions ideal for use across a variety of settings, from remote islands to rural areas, and particularly well-suited for decentralized locations where expensive infrastructure development can be avoided. The company's local service and installation network ensures quick and seamless equipment commissioning, as well as efficient after-sales support. 

With increasing demand for off-grid water solutions, especially in emerging markets and arid regions, SWS’s technology offers a significant growth opportunity. Additionally, the resilient, zero-carbon operation enhances preparedness for natural crises, making SWS’s products a strategic choice for ensuring water security in an unpredictable climate landscape.

Three patent families ensure the freedom to operate and help to build distribution partnerships with leading water treatment specialists in the target markets. The patent families are related to the one-of-a-kind mechanical adaptive valve system technology ANVS®. It automatically maintains the pressure constant, even when the feed flow to the reverse osmosis membranes is fluctuating due to the variable power obtained from the solar PV panels. The strong and comprehensive international patent portfolio enables Solar Water Solutions to scale up internationally and keep its competitive edge. 

Business model

The main path to expanding business is a distributor partner path. The objective is to foster current regional partnerships with local water treatment companies and establish new ones with a focus on remote municipal water infra projects, natural disaster response, hotel, food & beverage sector and private properties. Each distribution partner is a water treatment specialist company in the area, with turnkey solutions and O&M services for after-sales support. They are large enough to participate in local tenders with their local reference portfolios. Current key geographical focus areas are the Pacific Islands, Kenya and Scandinavia. In 2025 the objective is to enter the Mediterranean and Asian markets as well. 
 

SWS’s customer segments in priority order: 

  1. Municipal and other institutional customers that need clean water for general population in decentralized,
    off-grid remote areas 
  2. Natural disaster preparedness and response 
  3. Hotels & resorts and residentials in remote locations 
  4. Agriculture and food & beverage industry customers
