The impact of installing photovoltaic panels in fish ponds

Establishing floating photovoltaic (FPV) systems on aquaculture ponds can reduce demand for land use and affects food and solar energy production.

The fishery-photovoltaic complementary industry is an emerging industrial model in China that integrates aquaculture with the solar industry. This innovative model involves conducting aquaculture activities while installing photovoltaic modules on the water surface to harness solar energy for electricity generation.

The impact of the PV array installation in the lake on the H is 1.5 times compared to the H of the natural lake. Therefore, solar radiation plays a decisive role in the change process of H.

Château et al. (2019) explored the ecological effect of covering the fish pond with FPV panels through experiments and simulation. The results showed that FPV may have a certain negative impact on the growth of fish, but the energy efficiency can make up for it.

Our results show that the installation of FPV on fish ponds may have a moderate negative impact on fish production, due to a reduction in dissolved oxygen levels. However, losses in fish production are more than compensated by gains in terms of energy (capacity of around 1.13 MW/ha).

6 FAQs about [The impact of installing photovoltaic panels in fish ponds]

Does fishery complementary photovoltaic (FPV) power plant affect radiation and energy flux?

Meanwhile, the underlying surface of PV in land is significantly different from those in lake. The fishery complementary photovoltaic (FPV) power plant is a new type of using solar energy by PV power plant in China. The studies of the impact of FPV on the balance of both radiation and energy flux have been less presenting.

Does Floating photovoltaic (FPV) affect the aquatic environment?

With the aggravation of global warming and the increasing demand for energy, the development of renewable energy is imminent. Floating photovoltaic (FPV) is a new form of renewable energy generation. However, the impact of FPV on the aquatic environment is still unclear.

Can floating solar panels be used to cover fish ponds?

Numerous studies have developed mathematical models of fish pond ecosystems (Piedrahita et al., 1984; Svirezhev et al., 1984; Wolfe et al., 1986; Li and Yakupitiyage, 2003; Zhang et al., 2017; Granada et al., 2018), but to our knowledge, the ecological effects of covering fish ponds with floating solar panels have not yet been studied.

Are fishery complementary photovoltaic power plants a new surface type?

The deployment of photovoltaic arrays on the lake has formed a new underlying surface type. But the new underlying surface is different from the natural lake. The impact of fishery complementary photovoltaic (FPV) power plants on the radiation, energy flux, and driving force is unclear.

Does FPV power station affect aquatic environment?

Based on the above analysis, the construction of FPV power station has limited impact on aquatic environment, mainly reflected in the impact on DO. However, the development of “fishery and photovoltaics integration” project will lead to serious eutrophication of water bodies.

How FPV will affect the fishery and photovoltaics integration project?

With the increase of coverage ratio, FPV will lead to the overall reduction of T w in the construction water area, and the distribution of T w will be more uniform. For the “fishery and photovoltaics integration” project, reducing the peak T w in summer and reducing the diurnal fluctuation are more conducive to the growth of fish.
