Hydrelio®: the patented floating PV system
Hydrelio® technology is a patented water-based PV concept – first finetuned system to be industrialized – consisting of modular ‘lego-type’ floaters assembling into rows. Made from recyclable HDPE, the floating PV system enables to support PV modules above water while withstanding long-term environmental hazards, as wind, rain and snow.
To offer you the best experience with a long-lasting solution, our entire product range is qualified through technical tests for the reliability, performance and lifetime of your floating PV project. Hydrelio® technology comes standard with a 10-year warranty with the option to extend up to 25 years ensuring you a safe and bankable investment.

SIMPLE, DURABLE AND AFFORDABLE FLOATING SOLAR PV PLATFORMS
A simple and affordable alternative to ground-mount solar systems, Hydrelio® floating solar farms are particularly suitable for energy and water-intensive industries who cannot afford to waste either land or water. Wineries, dairy farms, fish farms, mining companies, waste-water treatment plants, irrigation districts and water agencies are all examples of organizations who benefit from the synergy that our system creates between sun and water.
From a technical point of view, our floating solar combines simplicity of construction and maintenance, flexibility of design, ecological safety and a durability proven by numerous tests. Hydrelio® is scalable and compatible with a wide range of PV equipment, and adapted to most types of reservoirs, dedicated for irrigation, water retention or treatment, hydroelectricity.
