The Advantages of Floating Solar
Malaysia's tropical climate and abundant reservoirs make FPV a highly strategic solution for land-constrained corporations and IPPs.
Zero Land Usage
Preserve valuable real estate and eliminate the need for costly land acquisition, clearing, and earthworks.
Higher Energy Yield
The cooling effect of water below the panels naturally limits thermal losses, boosting generation efficiency by up to 15%.
Water Conservation
The panels shade the water body, significantly reducing evaporation rates—crucial for dams and municipal water catchments.
Advanced Anchoring
Engineered mooring and anchoring systems designed to withstand monsoon winds and varying water levels.
Algae Reduction
By blocking excess sunlight from penetrating the water, FPV mitigates harmful algae blooms, improving water quality.
Hydro Integrations
Pairing FPV with existing hydroelectric dams utilizes existing transmission infrastructure and balances peak generation.
Ideal Applications for FPV
Industrial Retention Ponds
Factories with large cooling/retention ponds can offset massive internal loads without sacrificing factory expansion space.
Water Treatment Plants
Municipal and private water operators can utilize catchment reservoirs to power their highly energy-intensive pumping stations.
Utility Scale (LSS)
Independent Power Producers developing large-scale projects (e.g. under LSS) on dormant lakes or in synergy with hydro assets.
FPV-Grade Equipment
Inverters rated for high-humidity, marine environments (per the manufacturer datasheet) — important for reliable floating solar operation.

The FPV Engineering Challenge
Floating solar requires completely different engineering paradigms compared to standard ground-mounted or rooftop PV. Trexon's engineering team and specialist engineering partners focus on the crucial structural mechanics:
1Bathymetric Surveys: Mapping the underwater topography to design the optimal anchoring arrangement.
2Mooring & Anchoring: Elastic mooring lines and deadweight/helical anchors designed to handle wave action and wind loads.
3Floater Technology: Utilization of HDPE pontoons that are UV resistant and safe for aquatic ecosystems.
Frequently Asked Questions
Technical insights on floating solar deployments
Is floating solar more expensive than ground-mounted?
Initially, the CAPEX for FPV is higher than rooftop solar (our floating solar guide cites roughly RM 3.5-4.5/W against about RM 2.4/W for rooftop) due to the specialized floats and complex mooring systems. However, this is heavily offset by the zero land acquisition costs and the higher energy yield (up to 15% more generation due to water cooling), making the long-term LCOE highly competitive.
Are the solar panels safe mounted over water?
Yes. We use double-glass, high-durability modules with elevated waterproof ratings, paired with string inverters rated for the environment per the manufacturer datasheet (e.g. Sungrow SG110CX, IP65). All DC cabling is routed above the water level using cable trays integrated into the floaters.
Does FPV harm aquatic life?
The impact of FPV on a reservoir ecosystem depends on the site and is assessed in the environmental review. Shading can limit rapid algae growth, and food-grade HDPE floaters are specified so that they do not leach chemicals into the water.
