Off-Grid Rental Villas Secure a Sustainable Water Supply with Seawater Filtration

Challenge

Finland’s Archipelago Sea is the world’s largest archipelago by number of islands — nearly 40,000. At its center lies the Archipelago National Park, a protected area of rocky islets and forested islands.
In this unique and remote environment, Project Ö villas offer high-end, off-grid accommodations with all modern comforts, including clean water for drinking and bathing. Supplying reliable, safe water to these isolated islands posed a significant challenge.

Solution

The SolarRO MINI 150 desalination system provided an ideal fit for the project. Compact, energy-efficient, and fully solar-powered, it transforms seawater into safe, potable water — enabling independent, year-round villa use. The system eliminates the need for water deliveries or large-scale storage, ensuring comfort without compromise.

Impact

In operation for over seven years, the SolarRO MINI has delivered consistent, low-maintenance performance. It’s now a core part of the Project Ö experience — allowing guests to enjoy nature in peace, with clean water always available.
The system is a cost-effective, environmentally responsible solution for off-grid and remote hospitality applications, proving that sustainability and luxury can go hand in hand.
