Floating solar PV, on your water.
Turnkey commercial and industrial floating solar — pontoon design, mooring, LV/HV connection and G99 grid applications delivered end-to-end, from 250 kWp to multi-MW.
What we deliver
End-to-end floating solar — design, install and O&M
From bathymetric survey and mooring design through to G99 grid connection and 25-year O&M — one accountable team.
Mooring & anchoring design
Site-specific mooring design for varying water levels, wind loading and ice risk — bank, bed or dead-weight anchoring with corrosion-resistant hardware.
LV / HV connection & G99
Full LV/HV grid connection design and delivery — string inverters or central inverters, transformer packages and G99 DNO applications and witness testing.
Environmental & EA compliance
EA / SEPA / NRW consenting, ecological assessment and water-quality protection — with construction methods that preserve aquatic habitats and water usage.
Monitoring & performance
String-level monitoring, weather stations, alarm dashboards and remote diagnostics — with clear performance-ratio reporting against modelled yield.
Long-term O&M
Scheduled cleaning, mooring inspections, inverter servicing, string testing and 24/7 alarm response — keeping yield high across the 25-year design life.
Our process
Four stages from feasibility to first generation
Water-body survey, consents, on-water build and long-term O&M — a single accountable delivery partner.
- 01
Water body & yield survey
Bathymetric survey, water-level range, wind fetch and shading analysis — combined with irradiance modelling to size the array and forecast annual yield accurately.
- 02
Design, consents & DNO
Pontoon layout, mooring design, cable routing, environmental / EA permits and G99 / DNO connection applications — all handled by our in-house design team.
- 03
Installation & commissioning
On-shore panel assembly, floating pontoon deployment, anchor and mooring installation, submarine / floating cabling, inverter commissioning and G99 witness testing.
- 04
Handover & O&M
Full test certification, as-built drawings, O&M manuals, monitoring portal handover and long-term operations & maintenance contract — cleaning, mooring inspections and performance monitoring.

FAQs
Floating solar, answered
Why floating solar instead of ground-mount or rooftop?
Floating solar unlocks generation on unused water bodies — reservoirs, quarry lakes, mine pits and wastewater lagoons — without taking up land that has another use. Water-side cooling typically lifts yield by 5–10% versus equivalent ground-mount, and shading the water reduces evaporation and algal growth.
What size projects do you deliver?
Commercial and industrial arrays from around 250 kWp on private reservoirs up to multi-MW schemes on utility water bodies and disused quarries. Below 250 kWp the floating balance-of-plant usually isn't cost-effective versus rooftop or ground-mount.
What water bodies are suitable?
Man-made reservoirs, disused quarry lakes, mine pits, wastewater lagoons, settling ponds and irrigation reservoirs are ideal. We avoid ecologically sensitive natural lakes, tidal water and locations with high commercial navigation or ice loading.
How does the array cope with wind, waves and water-level changes?
Mooring is designed for site-specific wind fetch, wave height and vertical water-level range — with either bank-anchored, bed-anchored or dead-weight mooring, sized for the worst-case load case at each site.
Do you handle EA / SEPA / NRW permits?
Yes — we lead all environmental consenting, ecological assessment and licencing with the Environment Agency, SEPA or Natural Resources Wales, plus any water-abstraction, reservoir-safety or discharge permits the site holds.
What lifespan and performance can we expect?
25-year panel warranty, 12–15 year pontoon design life with staged refurbishment, 10-year inverter cover and modelled performance ratios of 78–83% depending on site. Water-cooling typically holds cell temperatures 3–8°C lower than ground-mount.
Do you cover the whole UK?
Yes — floating solar is delivered UK-wide, with survey, design and commissioning from our directly-employed team and vetted marine and civils partners for on-water works.
