Hyllstofta Waste Managment Facility

Nårab Invests in Solar Energy: Floating Photovoltaic System on Leachate Pond in Hyllstofta

Floating Photovoltaics on Leachate Pond

To reduce climate impact and increase the share of renewable energy, Norra Åsbo Renhållnings AB (Nårab) installed a floating photovoltaic system in early 2025 on one of the leachate ponds at the Hyllstofta waste facility. This initiative is part of the company’s efforts to make waste management more sustainable and energy-efficient.

The installation of the floating photovoltaic system has been possible thanks to Sunsurf Solar’s technology. The system consists of 42 modules and 126 bifacial solar panels with a total capacity of 100 kWp. This corresponds to an area of approximately 500 square meters and generates up to 90,000 kilowatt-hours of electricity per year. Since the installed panels are bifacial, they absorb direct sunlight from above as well as indirect light reflected off the water surface, resulting in a higher overall efficiency compared to conventional ground- or roof mounted solar installations.

Placing the solar panels on a leachate pond is a strategic solution for the landfill area at Hyllstofta. It utilizes otherwise unused space for electricity production without affecting Nårab’s land resources or the logistics of waste management.

A key advantage of Sunsurf Solar’s technology is the patented mooring system, which enables secure anchoring without damaging the pond’s protective liner. The system can also handle large fluctuations in water levels, making it particularly suitable for environments like leachate ponds.

The solar power produced is used directly in daily operations, reducing the need for purchased electricity and lowering operating costs while increasing self sufficiency.

The installation is part of Nårab’s long-term environmental and quality strategy, where circular thinking, sustainable energy sources, and efficient resource use are central. Through this initiative, Nårab demonstrates how solar energy and waste facilities can work hand in hand.

Tångagård in Falkenberg

Sunsurf Solar’s Technology Enables Sweden’s Largest Floating Photovoltaic System

Floating Photovoltaics at Tångagård

At the beginning of 2024, a floating photovoltaic system was installed at Tångagård in Falkenberg, utilizing Sunsurf Solar’s technology. The system consists of 42 modules and 126 bifacial panels, with a total capacity of 122 kW, covering an area of nearly 500 square meters. The annual production is estimated to be 100,000 kilowatt-hours, which is equivalent to the energy needs of five to ten households per year.

The bifacial panels capture sunlight from both sides, meaning they also benefit from reflections off the pond's water surface. Thanks to this efficient design, the system generates more energy than traditional solar installations, increasing overall energy efficiency.

The system is strategically located next to Tångagård’s pump house, making it possible to run the farm's pumps using solar energy. The system is anchored with Sunsurf Solar’s patented mooring system, which can handle large variations in water levels. This flexible solution is particularly suited for irrigation ponds and is a perfect fit for Tångagård’s needs.

By implementing this solution, Tångagård has not only reduced its energy costs but also taken another step towards more sustainable food production. The solar power contributes to the farm’s self-sufficiency and facilitates the production of green electricity without impacting cultivation areas or compromising food production.

"It's interesting to produce renewable energy on a surface that can't be used for anything else. I'm quite fed up with solar farms on arable land. I think it's complete nonsense. But having it on a surface that can't generate anything else, which also reduces evaporation, is great."

Project Peatland

A Development Project to Maximise the Potential of Otherwise Unused Land

Photovoltaic System on Peatland

Sunsurf continually strives to remain at the forefront of innovation and technological development. As part of our ongoing advancement in floating photovoltaic systems — and our ambition to make use of otherwise unutilized land — we have developed technology that enables installations on challenging sites such as peatlands, marshlands, and landfills.

The initial tests were carried out on peatland with challenging ground conditions, uneven terrain, and limited accessibility. The purpose of the test was to evaluate both the functionality of the technology and the efficiency of the installation process.

The results of the test were positive — the technology proved to be both reliable and efficient. One of its greatest advantages is the ability to enable solar installations in areas with low pH levels, where traditional methods such as piling are not feasible. This minimizes environmental impact — a critical factor when working with sensitive ecosystems like peatlands. Peatlands are vital carbon sinks, storing significant amounts of carbon dioxide and playing an essential role in climate regulation. At the same time, they cover vast areas that are difficult to utilize for conventional infrastructure. Developing energy solutions that can be implemented without disturbing these ecosystems is therefore of great environmental importance.

With our technology, solar panels can be installed on peatlands with minimal environmental impact. This allows us to contribute to the generation of green energy while safeguarding critical ecosystems. For Sunsurf Solar, this represents a significant step forward in our mission to develop sustainable solutions that support both the planet and the energy needs of the future.

“We had high expectations that the technology would perform well under these conditions, but it was still fantastic to see the results confirm our assumptions. We now look forward to using this solution in larger projects, where the land would otherwise remain unused.”

Floating Photovoltaic System at Säve Nursery Garden

Säve Nursery Garden at the Forefront of Floating Solar Energy

Floating Photovoltaic System at Säve Nursery Garden

Säve Nursery Garden, located north of Gothenburg, has long focused on sustainable practices to minimize its climate impact. The investment in a floating photovoltaic system became a natural extension of their long-term strategy to balance production and environmental responsibility while making smart use of existing resources.

Six modules with a total of 18 solar panels now float on the nursery’s irrigation pond, producing up to 10,000 kWh of green electricity annually. The system has proven to be stable even in harsh weather conditions, including snow and ice. On warm summer days, reflections from the water boost the output while evaporation has been reduced. The cooling effect from the water also helps keep the panel temperatures lower, ensuring more consistent performance—unlike rooftop systems, which can lose efficiency as panel temperatures rise.

The energy generated at Säve Nursery Garden is enough to power both the pumping stations and other parts of the operation, reducing their reliance on traditional energy sources. Thanks to Sunsurf Solar’s patented mooring system, the installation can also withstand large variations in water levels, making it a flexible and reliable solution that’s ideally suited to the nursery’s irrigation pond.
