Float System for Solar Power Generation

Float System for Solar Power Generation

For clients who want to flexibly use their assetsMaking it easier to introduce solar power generation via waterborne spaces to generate long-term energy.

Secure new source of revenueSecure new source of revenue

Operating power generating facilities in unused waterborne spaces that can be expected revenue by selling electric power.

Reduce environmental burdenReduce environmental burden

As forest clearing or ground improvement is not required to prepare for installation, environmental burden is reduced.

Installation available for a diverse range of locationsInstallation available for a diverse range of locations

The system can be installed in various locations including agricultural irrigation ponds, flood control reservoirs, industrial water retaining ponds, reservoirs and lakes.

High power generating efficiencyHigh power generating efficiency

Thanks to the cooling effect from the surface of the water, high efficiency power generation can be expected by controlling the rise of temperature in solar panels.

Controlling water evaporation and algae formationControlling water evaporation and algae formation

By having floats cover the surface of the water, light is blocked to prevent evaporation and formation of algae.

Ensuring sunlight with low-cost maintenanceEnsuring sunlight with low-cost maintenance

Compared with other land-based installations, our solution sees a relatively small impact with the amount of sunlight exposure on surrounding plants, which require it to grow. As a result, maintenance tasks such as weeding are not necessary.

System overviewAs there are few obstacles blocking sunlight on water which inherently provides cooling effect, waterborne locations can be expected higher power generation capacity than land-based installations.
In addition, float systems are also expected to have the effect of improving water quality by inhibiting the formation of algae through prevention of sunlight from entering the water.

System OverviewSystem Overview

System Overview

1. FloatsThe float is a buoyant body that rests above the water and also acts as a solar panel installation base. It also includes components for the fixing of mooring cables.

2. Float for ScaffoldingIt is mainly placed on the outer periphery, and it is used as a scaffold for installation and maintenance of the mooring rope.

3. Upright standsWhen mounted to the float, this acts as a base component that produces an angle of inclination for the solar panels.

4. BridgesThe bridge is a component that connects floats to one another and serves as a foothold during construction and maintenance.

5. Binding BandsThe binding band fixes floats together. Two varieties are available to match the wind pressure load.

High-quality, high-performance float system

High-quality
Materials
and Design

  • Float will not sink thanks to polystyrene foam filling.
  • Between three and five times the rigidity strength of products designed to hollow specifications.
  • Highly safe wind pressure load calculations can be made.

Simple
Construction

  • The lightweight materials can be carried by a single person.
  • Assembly is easy and a minimum of two people can perform installation.
  • Simple and speedy construction with binding bands.

Exceptional
Economy

  • Higher power generating efficiency than land-based systems.
  • Shorter construction periods thanks to the simple construction.

Do not sink even when damaged

As the insides of the floats are filled in polystyrene foam, they will not sink even when damaged.

Simple float assembly

Floats are easily connected together using binding bands. That makes it possible to construct large-scale systems.

Simple panel mounting

Solar panels from several different manufacturers are suppotted, with speedy installation using bolts and brackets.

Other Features

  • Increase power generation efficiency using the cooler environment above the water
    The floats underneath the solar panels have wide openings at their center to promote a cooling effect, with the aim of improving the power generating efficiency of the panels.
  • High durability
    As high-density polyethylene(HDPE) which is resilient against UV light is used, the product does not degrade easily and can be used with peace of mind on a ong-term basis.
  • Supports solar panels from a wide range of manufactures
    Solar panels from many different manufacturers can be installed on the system.
    Outer dimensions for installable panels: Width:1500-1680mm X Depth: 980-1000mm X Height: 35-50mm
  • Anchoring Service
    We provide anchoring design and installation service and test on every anchor to ensure qualities.

Environmentally friendly

Contains no harmful substancesContains no harmful substances

Contains no harmful substances

Materials of our float system do not contain any harmful substances. We use safe materials that can be manufactured into water pipes and lunch boxes.

No impact on water qualityNo impact on water quality

No impact on water quality

The dissolution test confirmed that materials will not dissolve any substance within water that may affect the water quality.

FAQ

How much time and labor are required for assembly and installation?

In one day, four people can assemble the float system and install the solar panels for around 20-kW(around 80 solar panels)

How long will the system last?

Under regular usage, the system should last for around 20 years.

When should electrical wiring work be performed?

When the solar panels are mounted on land or in a work yard, connect the wiring between panels. Overall wiring is performed once the floating system has been set up on the water.

What is the maximum number of panels that can be connected together?

The number varies depending on conditions of the installation location. When provided with specifics about the installation location and other variables, we can propose an installation plan.

Does this system pollute the water quality or damage the ecosystem of the surroundings?

Experiments have proved that the equipment components that we use will not melt under normal usage. It will therefore not pollute the water quality or damage the ecosystem of the surroundings, and it can coexist with the surrounding flora and fauna.

What happens if we cannot install the system by ourselves?

Please do not worry. We have an additional installation and setup service at your site. If you encounter any difficulties in setting up the system in the future, please do not hesitate to contact us.
