OASIS BIOSOLAR, the 1st biosolar roof on the market

The System

OASIS is Le Prieuré’s patented solution for optimizing water resources and developing roof gardens. The BIOSOLAR version is the 1st hydro-bio-solar roof on the market.

The advantage of OASIS BIOSOLAR is its 3-in-1 synergy:

• Increased electrical output: evaporation from the greening complex cools the panels, boosting their output during hot spells (+7.51% according to a study from June 2023 to June 2024),
• Optimized water management: the system captures and evaporates 80 to 100% of annual rainfall, helping to achieve “zero discharge”,
• Biodiversity encouraged: the shaded areas created by the panels create ecosystems conducive to the development of diverse flora.

 

HYDROSTOCK tanks are connected to each other to form a uniform water reservoir on the roof. The water stored in the tanks (52 L/m²) rises by capillary action to the substrate, or evaporates.

A flow limiter is located in each tank zone (approximately every 80 tanks) to allow water that has not been evapotranspired or consumed by the plants to be drained off, at a micro-flow rate of up to 0.5 L/s/ha.

The Modulo multimodal plate allows solar panels to be attached without impacting the waterproofing membrane. Modulo plates also act as a support for the culture layer (the substrate).

The system’s own weight allows it to be weighted down: the installation characteristics (choice of rails, substrate thickness, etc.) are defined following a preliminary study by Le Prieuré’s Bureau d’Ingénierie Verte.

For use on all types of roofs, with a maximum pitch of 5%.

OASIS BIOSOLAR is a joint innovation from Le Prieuré and Adiwatt.
