Bangladesh has 7 million hectares of water bodies — haors, baors, fish ponds, and irrigation reservoirs. Floating solar (floatovoltaics) can generate electricity from these surfaces without using agricultural land, offering a unique opportunity for Bangladesh's energy transition.
Bangladesh faces a fundamental constraint for large-scale solar deployment: land scarcity. With one of the world's highest population densities, every hectare of agricultural land is precious. Yet Bangladesh has an extraordinary alternative resource — approximately 7 million hectares of water bodies, including haors (seasonal wetlands), baors (oxbow lakes), fish ponds, and irrigation reservoirs. Floating solar (also called floatovoltaics or FPV) deploys solar panels on pontoons or floats on these water surfaces, generating electricity without consuming agricultural land.
Floating solar systems typically generate 5–15% more electricity than equivalent land-mounted systems in the same location. The reason is the cooling effect of the water beneath the panels — solar panels lose efficiency as they heat up, and the evaporative cooling from the water surface keeps panel temperatures lower. In Bangladesh's hot and humid climate, this performance advantage is particularly significant during the April–June peak heat period.
| Water body type | Suitable for floating solar? | Typical application | Capacity range |
|---|---|---|---|
| Fish ponds (private) | Yes — excellent | Farm power + fish production | 10 kWp – 2 MWp |
| Irrigation reservoirs | Yes — excellent | Pump power + grid supply | 100 kWp – 10 MWp |
| Haors (seasonal) | Seasonal only (dry season) | Seasonal generation | 1 MWp – 50 MWp |
| Baors (oxbow lakes) | Yes — good | Community power | 50 kWp – 5 MWp |
| Industrial ponds | Yes — good | Factory power | 50 kWp – 5 MWp |
One of the most promising applications of floating solar in Bangladesh is agri-aqua solar — combining fish farming with solar power generation on the same water body. The solar panels provide shade that reduces water temperature and algae growth, improving fish yields. The electricity generated powers aerators, water pumps, and processing facilities. Studies in China and India have shown that agri-aqua solar systems can increase fish yields by 10–20% while generating significant electricity revenue.
SREDA (Sustainable and Renewable Energy Development Authority) has identified floating solar as a priority technology for Bangladesh's renewable energy expansion. The Bangladesh Power Development Board (BPDB) has issued tenders for floating solar projects on government-owned reservoirs. Private sector investors can develop floating solar under the net-metering framework for systems up to 120% of sanctioned load, or under the Independent Power Producer (IPP) framework for larger utility-scale projects.
