AS ECO-FRIENDLY AS WATER-MAKING CAN BE
About Solar Water Solutions
Decentralized Solar Desalination Systems for Remote Utilities and Communities
Solar Water Solutions — Engineering Water Independence
Solar Water Solutions is a Finnish cleantech company specializing in decentralized solar-powered desalination systems for seawater and brackish water treatment.
For over 10 years, we have engineered and delivered containerized and skid-mounted reverse osmosis (RO) systems designed for off-grid and hybrid operation. Our solutions provide reliable freshwater production for utilities, municipalities, industry, islands, and remote infrastructure where grid power, fuel logistics, or centralized water networks are limited.
To date, we have delivered over 450 small- and mid-sized water treatment systems globally, supporting private, municipal, and governmental projects in decentralized environments. Our installed base enables the production of significant volumes of clean water annually, helping communities and industries reduce dependency on diesel, water transport, and centralized infrastructure.
We focus on what matters most in critical water infrastructure:
- Proven reverse osmosis technology
- Integrated pre- and post-treatment
- Energy-efficient solar operation
- Containerized plug-and-play deployment
- Remote monitoring and automation
- Transparent cost per cubic meter
In strategic partnership with LORENTZ, we integrate advanced solar pumping and control technology to ensure reliable performance in fully off-grid conditions. Together, we develop scalable desalination solutions that combine renewable energy, operational simplicity and long-term durability.
Built for Real-World Conditions
Water scarcity, climate variability and infrastructure gaps require decentralized systems that are robust, energy-efficient and easy to deploy.
Our SolarRO product family covers capacities from small-scale remote applications to commercial desalination systems up to 300 m³/day (seawater) and 500 m³/day (brackish water). Each system is engineered for:
- Remote municipalities
- Coastal and island communities
- Industrial sites
- Climate resilience and emergency preparedness
- Off-grid infrastructure projects

In Partnership with LORENTZ – Advanced Solar Pumping Integration
Solar Water Solutions works in strategic partnership with LORENTZ, a globally recognized manufacturer of solar-powered pumping and drive systems.
Together, we co-develop and integrate solar pumping, control systems and power electronics into our SolarRO desalination platforms. This enables fully off-grid operation, optimized solar energy utilization and stable performance even under fluctuating irradiation conditions.
LORENTZ technology is deployed in more than 130 countries and is known for reliability in demanding environments. By integrating advanced pump controllers and drive systems into our containerized desalination units, we achieve:
- High system uptime
- Predictable and stable operation
- Optimized energy efficiency
- Reduced operational complexity
- Long component lifetime
This partnership combines Finnish water treatment engineering with advanced solar pumping technology — delivering resilient, low-maintenance desalination infrastructure for remote and decentralized applications.
Resilient Solar Desalination Infrastructure for Remote Environments
In remote regions — from island communities to inland arid areas — reliable access to clean water requires robust, energy-efficient infrastructure.
Our systems utilize reverse osmosis (RO), a proven desalination and water treatment technology capable of removing up to 99% of dissolved salts and contaminants. Traditionally, desalination has depended on stable grid power or diesel-based generation. Solar Water Solutions addresses this challenge by directly integrating renewable energy into the desalination process.
Each system is engineered for:
- Seawater desalination
- Brackish groundwater treatment
- Off-grid and hybrid energy operation
- Autonomous control and remote monitoring
- Simplified maintenance and long operational life
Our decentralized approach provides a scalable alternative to water trucking and bottled water supply, reducing logistics dependency, fuel consumption and long-term operational costs.
Tailored Engineering and Technical Support
Every water project requires site-specific engineering and technical validation.
Before system configuration, we evaluate:
- Daily freshwater demand (m³/day)
- Raw water analysis (seawater, brackish, borehole or surface water)
- Available power source (solar, grid, battery or hybrid)
- Installation conditions and logistical constraints
Our engineering team supports clients from initial system sizing through configuration, deployment and commissioning. We ensure that each desalination solution is technically optimized for its operating environment and long-term performance expectations.
Through our global partner network, we also provide ancillary equipment and turn-key water treatment systems tailored to municipal, industrial and remote infrastructure applications.
