Products from Sunsurf Solar
Next-generation systems for renewable energy
Sunsurf Solar develops three patented systems for renewable energy on water and land: PowerModule™ for floating solar, PeatModule™ for peatland and landfill, and FlexibleMooringSystem™ for anchoring with 6 m of water-level variation. All are dimensioned to Eurocode and DNV-GL standards — built to hold up under snow loads, ice formation and high winds without giving up safety or output.
PowerModule™ — floating solar
Our system for leachate ponds, irrigation reservoirs and industrial ponds — generating power on surfaces where conventional solar can't go.
PowerModule™ is built with more than a metre of clearance above the water. Light passes through, air moves freely beneath the modules, and the components stay naturally cool — which extends working life and keeps impact on the water below to a minimum.
The open design lets sunlight reach the panels both directly and indirectly, reflected off the water surface and the surrounding aluminium and steel. Combined with bifacial panels, that can lift output by up to 15% compared with conventional ground-mounted monocrystalline panels at 25 °C.
Design features — PowerModule™
Open design
01Built to keep the cells cool — both through airflow and the natural cooling effect of the water beneath.
Maximised output
02Up to 15% more yield than conventional solar panels, thanks to bifacial panels and reflection off the water.
IP-protected design
03IP-rated electrical design with a robust structural frame in aluminium or coated steel.
Modular
04Sized to the shape of the pond, the capacity needed, and the optimal orientation.
Long service life
05A 40-year technical service life on the mounting system.
Service and maintenance
06Components stay easy to reach thanks to careful system design. Each PowerModule™ comes with an integrated walkway.
Fast installation
07Designed for simple, rapid deployment. Fully pile-free.
Winter-ready
08Built for the toughest winter conditions — snow loads, ice formation and freeze–thaw cycles — to Eurocode and DNV-GL standards.
Anchoring — FlexibleMooringSystem™
The systems are anchored to land using Sunsurf Solar's FlexibleMooringSystem™, built to handle water-level changes of more than 6 metres. It delivers stable operation while leaving the bottom undisturbed.
The anchoring keeps water turbidity to a minimum and doesn't affect sedimentation, protective liners or treatment processes. That makes it a good fit for sensitive environments — ponds, reservoirs and water storage basins.
Built for harsh winter conditions
The systems are designed for the toughest winters. Structure and anchoring are dimensioned to Eurocode and DNV-GL standards to handle heavy snow loads, ice formation and freeze–thaw cycles without losing stability or output.
The result is a reliable system year-round — snow, wind or ice. Because everything is pile-free, installation is fast and cost-effective. Sunsurf has also developed installation methods that keep disruption for the customer to a minimum. Once it's running, service and maintenance are straightforward thanks to our access platforms, and each PowerModule™ comes with an integrated walkway.
PeatModule™ — for peatland and landfill
Our system for large-scale solar parks on landfills, peat bogs and wetlands — sites with the most demanding ground conditions.
PeatModule™ is built for ground that conventional solar can't handle. On peatland, bog, marsh and landfill — where pile driving simply isn't possible — it delivers a stable, durable foundation.
The system is flexible and copes with both shifts in ground level and temporary surface water, without giving up safety or output. That makes renewable generation possible in places where it used to be off the table.
PeatModule™ sits on robust HDPE (high-density polyethylene) pontoons, allowing installation on the most challenging ground.
Design features — PeatModule™
Pile-free
01PeatModule is surface-mounted — no pile driving.
East–west orientation
02Configured for east–west production for an even daily output curve.
Biodiversity
03Designed to let light through to the ground below and support biodiversity.
IP-protected design
04IP-rated electrical design with a robust structural frame in aluminium or coated steel.
Modular
05Sized to the terrain and the capacity needed.
Long service life
06A 25-year service life on the panels and 40 years on the mounting system.
Service and maintenance
07Service walkways make it straightforward to access the installation.
Fast installation
08Designed for quick deployment — no pile driving, no excavation.
PowerModule™ vs PeatModule™ — which one fits my site?
Both systems are built for harsh winter conditions. The difference is what they sit on: PowerModule™ floats on water, PeatModule™ rests on land without pile driving.
Where it goes
01PowerModule™: water — leachate ponds, irrigation ponds, reservoirs, industrial ponds. PeatModule™: land — peatland, bog, marsh, landfill and wetland.
How it mounts
02PowerModule™ floats on HDPE pontoons, anchored to shore via FlexibleMooringSystem™. PeatModule™ is surface-mounted on HDPE pontoons — fully pile-free.
Panel orientation
03PowerModule™: south-facing with more than 1 m of clearance above the water, bifacial panels. PeatModule™: east–west for an even daily production curve.
Service life
04Both systems: 40 years on the mounting structure; 25–30 years on the panels with at least 80% of rated output after 25 years.
Typical customer
05PowerModule™: environmental services (Miljöhantering i Jönköping, Nårab), plant nurseries (Säve), agriculture (Tångagård). PeatModule™: landfill owners, peatland owners, rewetting projects (Kättilstorp).
Reference installation
06PowerModule™: Sweden's largest floating solar park (Jönköping, 116.1 kWp, 2025). PeatModule™: Sweden's first peat-adapted solar installation (Kättilstorp, 2024).
Certified materials
The modules are built in aluminium or coated steel — for a long service life, low weight and strong corrosion resistance. The materials perform well in demanding environments like leachate ponds, landfill and peatland.
The aluminium is sourced from Nordic raw materials and processed in Sweden. The steel is coated to resist corrosion even in aggressive conditions. Manufacturing runs in close partnership with certified suppliers, in line with ISO 9000 and ISO 14000.
The pontoons are made from high-density polyethylene (HDPE) by suppliers certified to ISO 9000 and ISO 14000. HDPE holds up under UV radiation, mechanical stress and chemical exposure, and is recyclable — a more responsible material choice.
