Floating Solar Installation: A Growing Sector for Water-Based Energy
Floating photovoltaics (FPV), also known as floatovoltaics, represent one of the fastest-growing segments in renewable energy. Global installed FPV capacity reached 5.9 GW by 2023, with the market valued at approximately $7.8 billion in 2025 and projected to grow at a CAGR exceeding 34%.
Why Floating Solar?
FPV systems installed on reservoirs, lakes, and industrial ponds offer distinct advantages over ground-mounted alternatives:
- No land competition — critical in land-constrained regions
- Reduced evaporation — panels shade water surfaces, conserving resources
- Higher efficiency — water cooling effect boosts panel output by 5–10%
- Dual-use infrastructure — existing grid connections at hydropower reservoirs reduce interconnection costs
Market Leaders by Segment
| Segment | Leading Companies | Key Differentiator |
|---|---|---|
| Freshwater FPV (pontoon-based) | Ciel & Terre, Sungrow FPV, Scotra | Proven at scale; 100+ MW projects |
| Offshore / Ocean FPV | SolarDuck, Ocean Sun, Swimsol, Oceans of Energy | Wave-resistant designs for marine environments |
| EPC & Project Development | D3Energy, BayWa r.e., Tractebel | Full turnkey project delivery |
Selecting an FPV Contractor
When evaluating floating solar installation companies for a reservoir or water body project, utility developers should assess:
- Track record at scale
- Has the company delivered projects above 10 MWp? Ciel & Terre has completed 340+ projects across 30 countries; Sungrow FPV has supplied over 3 GWp of floating systems globally.
- Anchoring & mooring expertise
- Water depth, bottom conditions, and water-level fluctuation dictate anchoring solutions. Look for companies with experience in rock-bolt, cable, and deadweight anchoring systems.
- Environmental compliance
- FPV projects require environmental impact assessments addressing aquatic ecosystems, water quality, and wildlife corridors.
- Local permitting knowledge
- Regulations vary significantly by jurisdiction. Companies with multi-country experience can navigate complex permitting landscapes.
