04 — Why develop FPV with WALDEVAR

Stable. Efficient. Economically smart.

Many still see FPV through outdated myths. Let's talk facts — for forward-thinking enterprises and governments, FPV is a strategic advantage in a low-carbon economy.

  • Cooler panels, more energy

    The water's cooling effect enhances panel performance — higher output and returns than ground-mounted systems.

  • Less evaporation

    Covering the surface reduces water evaporation and helps protect vital water reserves.

  • Less algae

    Shading the water limits algae proliferation — a smart long-term investment for the reservoir.

  • No land taken

    Water surfaces become energy hubs, preserving land for agriculture and development.

  • Fully reversible

    No excavation, no deforestation and a minimal environmental footprint.

  • 25-year lifespan

    Designed for durability — long-term energy production and stable returns.

05 — How it works

A power plant that floats.

PV modules · floats

Modules ride on our own floats

Floats made in the WALDEVAR FPV factory carry the modules. Cooled by the water, they produce more than the same modules on land.

Underwater cable

From the island to the shore

The energy leaves the floating island through underwater cables, laid along the bed to the shore.

Central inverter · transformer

Converted and stepped up on land

On the shore, the central inverter turns direct current into alternating current and the transformer raises it to grid voltage.

06 — Site selection

Choosing the right water body.

The factors we weigh before designing a floating solar photovoltaic plant.

FactorHigh preferenceLow preference

Location

  • Near populated regions
  • Easily accessible by road
  • Secured
  • Near key production points, for logistical efficiency
  • Remote places with high transportation cost

Weather & climate

  • High solar irradiation
  • Little wind or storms
  • Calm water
  • Low-rainfall areas where sustainable water management is critical
  • Cold regions above 55° latitude
  • High winds and waves, risk of natural disasters
  • High water currents
  • Drought events that expose the water bed

Type of water body

  • Hydroelectric power reservoirs
  • Mining support reservoirs
  • Gravel pits
  • Industrial process water reservoirs
  • Cooling water reservoirs for power plants
  • Multi-purpose industrial supply reservoirs
  • Tourist or recreational sites

07 — Manufacturing

Europe's largest FPV factory.

Strategically positioned along Bucharest's main Ring Road, with exceptional logistic advantages. To reduce its own carbon footprint, the factory is powered by a 2.6 MW photovoltaic park backed by a Battery Energy Storage System — and uses state-of-the-art blow-molding and injection equipment.
