This article is going to talk about advantages and prospects of "Fish-light momplementary" mode of aquatic PV.
Aquatic photovoltaic refers to the construction of photovoltaic power plants (floating PV solutions
) in water environments such as ponds, small lakes, and reservoirs to solve the problem of a large area of traditional photovoltaic power generation. The internal rate of the project return of floating photovoltaic systems
on the water is higher than that of ground or rooftop power stations. Today, we will talk about the advantages and development prospects of the "fish-light complementary" mode of photovoltaic on water.
Fish-light complementary mode on the water
According to the different water depths, the photovoltaic foundation is mainly divided into precast concrete pipe pile foundation and floating foundation. The floating foundation is mainly divided into traditional buoy + support foundation and photovoltaic special integrated buoy foundation.
Different from ground power stations, water photovoltaic power stations do not occupy land resources, which is very suitable for the central and eastern regions where water resources are rich and land resources are scarce. Not only that, but water photovoltaic power stations also have technical advantages, because the water has a cooling effect on photovoltaic modules, which can inhibit the rise of module surface temperature and reduce radiation from the surface of the water. The overall power generation is about 10%-15% higher than rooftop or ground photovoltaic power generation systems under the same conditions. In addition, "fishery and light complementary" and other "photovoltaic +" business models realize the increase in fishery income on the basis of power generation.
Fish-light complementarity refers to the combination of fishery and photovoltaic power generation. The photovoltaic panel array is erected above the surface of the fish pond, and the water below the photovoltaic panel can be used for fish and shrimp farming. The photovoltaic array can also provide a good shielding effect for fish farming, forming a new power generation mode of "generating electricity, and raising fish".
As a new kind of distributed photovoltaic mode, the fishing light complementary is still in the initial stage of development. There are various problems such as lack of construction standards. The maintenance is difficult, but the emergence of this model in our development of distributed photovoltaic power stations puts forward a new train of thought. It is combined with local actual characteristics, which does not stick to the traditional mode. Innovation is the first.
Advantages of the fish-light complementary photovoltaic mode
1. The shading effect of the photovoltaic module can reduce water surface temperature, water evaporation, and the probability of fish and shrimp being scalded to death by water.
2. Reduce photosynthesis of water surface plants. It can inhibit algal reproduction to a certain extent, improve water quality, and provide a good growth environment for fish.
3. Bring additional photovoltaic power generation income and multiply the added value of aquaculture.
The fishing-light complementary photovoltaic power generation mode innovatively combines photovoltaic and fishery. The two industries will occupy a large number of land resources and achieve multiple benefits. It not only achieves three-dimensional reuse in space, saves land, but also outputs environmentally friendly clean energy.
