The concept of combining solar panels with fish farms, often referred to as aquavoltaics, is gaining traction as a sustainable and innovative solution. Here are some key points about this approach:
Benefits of Aquavoltaics:
Energy Generation: Solar panels installed over fish ponds generate renewable energy, reducing reliance on traditional power sources.
Water Conservation: The shade from the panels reduces evaporation from the ponds, conserving water.
Temperature Control: The panels help lower water temperatures, creating a more favorable environment for fish and reducing the risk of fish dying from high temperatures.
Algae Control: Reduced sunlight penetration can help prevent harmful algal blooms, improving water quality.
Dual Land Use: This approach optimizes land use by combining energy production with aquaculture.
Global Examples:
Taiwan: The government has been promoting aquavoltaics to meet renewable energy goals, with projects like the 42.9-megawatt facility in Tainan.
China: Several large-scale projects, including a 940-megawatt floating solar array at a fish farm in Jiangsu, are underway.
Other Countries: Nations like Bangladesh, Chile, and Norway are also experimenting with this concept.
Challenges:
Technical Issues: Engineering water-hardy floating solar arrays and specialized mooring systems can be challenging.
Environmental Impact: The impact on aquatic life and ecosystems is still under investigation.

Solar panels installed over fish farms in hot climates can provide several benefits, including:
- Solar panels generate clean, pollution-free electricity.
- The shade from the panels can help maintain optimal water temperatures and reduce algae growth. This can create a healthier environment for aquatic life.
- The shade from the panels can reduce water evaporation, which can be especially beneficial in dry climates.
- Solar panels can be a cost-effective renewable energy resource for fish farms.
- The shade from the panels can help improve yields of seafood. For example, a study in China found that solar panels increased shrimp and sea cucumber yields by 50%.
- Mounting solar panels above water can have a natural cooling effect.
- Bifacial solar panels can generate power from both sides, including the light that reflects off of the water.
- Floating panels can increase the weight and stability of the structure, and prevent soiling on the panels.
