Laketricity combines solar energy with water conservation

Discover floating solar

Floating solar power is based on the same electrical principles as ground-mounted and rooftop power plants. What sets it apart is its removeable floating structure, which means it can be installed in unused spaces to deploy large capacities on all types of water.

This is one of the least impacting applications of photovoltaics, since it relies on the use of spaces already in use or exploited for another activity. In fact, this technology meets the growing need to produce clean energy and represents a sustainable solution to land scarcity, the preservation of precious land, deforestation and conflicts of use with existing activities.

Today, the potential for floating solar power worldwide is estimated at over 4TW  (source : DNV Institute study published in 2021). Offering a wide variety of applications, the development possibilities and compatibilities are vast.

Floating solar power means producing renewable energy without use conflicts

  • Solar power is an endless source of energy.
  • A wide range of applications: A large number of activities are compatible with floating solar power: agricultural, industrial, hydroelectric, mining, recreational, etc.
  • Combinations of solar technologies: a floating solar project can also be combined with another energy-producing solar installation, such as energy storage systems, agrivoltaics, rooftop solar, ground-mounted solar, etc. Depending on the configuration of your site, our teams can design projects with multiple solar energy sources.
  • Limit evaporation: preserve your water resources with a floating solar power plant that acts as a barrier to limit evaporation.
  • Compatible with drinking water ponds: the technologies we use at Laketricity meet the most stringent standards applicable to water intended for human consumption.
  • An integrated solution: floating solar power can have a positive impact on biodiversity. For example, it can limit algae growth. It is also a way of financing the development of measures to promote biodiversity on the sites entrusted to us.
  • Passive income generator for property owners: as the owner, you have nothing to do and nothing to pay out: we take care of everything.
  • Floating solar power is a good neighbor: during operation, it generates no noise and is visually unobtrusive. At Laketricity, we co-construct our floating solar projects by including all stakeholders, local authorities and residents, so as to take local needs into account.
  • A source of green electricity for electro-intensive users: installing a floating solar power plant on an industrial or water treatment pond represents a real economic advantage for your business or region. Thanks to our self-consumption solutions, you can significantly reduce your electricity bills.
  • The 3rd pillar of solar energy: floating photovoltaic systems can produce green energy on a large scale, helping to diversify the energy mix and replace fossil fuels.

Laketricity, at your project’s service for advanced, tailored solar solutions

In addition to developing your floating solar project, we can integrate other solar power generation solutions to meet your needs and objectives.

Floating solar power plants well integrated into their environment

At Laketricity, we strive to ensure that our floating solar power plants are well integrated into their environment. To achieve this, we imagine and design tailor-made solutions and systems to cover needs linked to the preservation of biodiversity, or to the social or economic activity of your site.

We mobilize all the expertise needed to build an intelligent floating solar project, working with highly qualified design offices to cover environmental, landscape, tourism and flood risk issues.

Our environmental integration approach

Encouraging aquatic biodiversity development

We respect the natural environment of the water bodies on which we develop our floating solar projects. For instance, we facilitate the growth of aquatic biodiversity on the site by installing vegetated islands. These islands allow aquatic vegetation to develop spontaneously, creating new habitats for aquatic fauna. Fish, in particular, thrive in these areas: spawning grounds, resting places, breeding grounds, nurseries, etc.

Protecting terrestrial biodiversity

We also contribute to preserving terrestrial biodiversity through various actions, depending on the site’s needs and possibilities. For example, we can set up an embankment revegetation program to help create nesting areas for birds. Certain areas of the site can be left completely free to respect the avifauna living there. We can also install insect hotels and beehives close to the water body to encourage pollination, as well as hedgerows.

Integrating the power plant into the landscape

At Laketricity, we make every effort to integrate the electrical equipment of our floating photovoltaic projects into the existing landscape. For example, we can install wooden cladding over the transformer cabinet on the embankment slope. We can also install vegetated islands on the water to conceal the floating solar power plant from the shore, as well as encouraging pollination and bird nesting.

Developing additional facilities according to site use

Depending on the existing operations on-site, we can consider additional solutions when developing a floating solar power plant project. For example, we can install an energy storage system: energy is stored via a system that optimizes electricity consumption during peak demand periods. We can also install hydrogen stations or charging stations for electric vehicles, depending on your needs.

A location and anchoring that respect the site and are adapted to its specific features

Right from the preliminary development phases, we carry out the environmental studies required for the successful development of the project. We also ensure that the plant is sized to meet the specific requirements and challenges identified for your site.

Indeed, our engineering teams design tailor-made layouts for the photovoltaic power plant and its anchoring. This enables us to guarantee optimized energy production, while respecting the environment and ensuring the plant’s long-term safety.

To develop our floating solar projects, we take a local approach

If you have a question about floating solar power, we have the answer:

Is there a size or capacity limitation?

There is no size limit for a full-scale floating photovoltaic installation. For anchoring reasons, large-scale projects must be composed of several PV islands.  

For example, the 70 MWp de Anhui Cecep (China) is composed of 13 floating PV islands.

What is the efficiency of photovoltaic panels installed in a bi-facial configuration?

Bifacial photovoltaic panels benefit from a better waterproofing and are therefore perfectly compatible with floating solar projects. Electricity production is increased thanks to the backside of the panels, even if limited because the light reflection (albedo) is about 8%. Moreover, the cost difference with mono-facial panels is small.

What type of anchors can be used?

The type of anchoring proposed for the project is always discussed between the technical teams of Ciel & Terre, Laketricity and the owner of the water body in order to offer the best possible solution. In general, we consider three main types of anchors: drilled anchors, percussion anchors and concrete blocks. If none of these can be used, other types of anchors can be investigated.
