Photovoltaic aquaponics
Photovoltaic aquaponics: above photovoltaic power generation, below growing vegetables and fish
Aquaponics technology, as an innovative agricultural model, combines aquaculture with hydroponics to realize the recycling of resources and ecological balance. The "photovoltaic aquaponics" model not only follows the basic principle of aquaponics, but also introduces photovoltaic technology on this basis to achieve the integration of agriculture and clean energy.
The core of aquaponics technology is its ability to recycle water. In this model, fish excrement can be used as a natural fertilizer for vegetable growth, and vegetables can absorb these nutrients at the same time, but also purify water quality, providing a good living environment for fish. This cycle not only greatly reduces the consumption of water resources and the use of chemical fertilizers in traditional agriculture, but also effectively improves the sustainability of agricultural production.
Based on the basis of aquaponics, the photovoltaic aquaponics model further expands the application range of this technology. By installing photovoltaic panels on the top of the greenhouse, it can both provide the required power for agricultural production and transmit excess power to the grid, achieving a two-way flow of energy. This model not only improves the efficiency of energy use, but also creates additional economic benefits for farmers.
An efficient model of dual use, complementary agriculture and light
"One greenhouse for dual use" refers to both agricultural production and electricity production in the greenhouse. This layout maximizes the use of limited land resources and improves the comprehensive utilization efficiency of land. The "agro-light complementarity" reflects the synergistic effect between agricultural production and photovoltaic power generation, which not only guarantees the electricity required for agricultural production, but also provides clean energy for other fields outside agricultural production through photovoltaic power generation, promoting the diversified use of energy.
Innovative practice of dual system production mode
The photovoltaic aquaponics model adopts a closed-loop and open-loop dual system production mode, which makes the system more flexible and efficient. In summer, it is dominated by an aquaponics system that uses natural light for photosynthesis while providing electricity for agricultural production through photovoltaic modules; In winter, through the indoor fishing aquaponics cycle, photovoltaic power generation is used to supplement light and heat, ensuring that crops and fish can grow normally in winter conditions. The flexible switching of this mode ensures the possibility of annual production and improves production efficiency and economic benefits.
The extension and improvement of industrial chain and value chain
Through the PV aquaponics model, the added value of agricultural products has been improved. Due to the adoption of environmentally friendly and sustainable production methods, the agricultural products produced are greener and healthier, meeting the market demand for high-quality agricultural products. At the same time, excess power can be sold to the grid, creating additional income for farmers. This model also helps to promote the extension of related industrial chains and value chains, such as photovoltaic equipment manufacturing, system maintenance, deep processing and sales of agricultural products, and further promote the development of local economies.
Although this model faces challenges such as technical and management difficulties and model limitations, it still provides us with a valuable perspective on the possibility of combining agricultural production with environmental protection and energy utilization.
