How can agriculture utilize photovoltaic energy storage by improving returns?

In recent years, agricultural production has faced increasing challenges, including climate change, rising energy costs, and price volatility of agricultural products. And with the continuous progress of renewable energy technology, photovoltaic energy storage systems are gradually entering the field of agriculture, becoming an important breakthrough for sustainable agricultural development.

Traditional agriculture faces two core challenges: rising energy costs and low land utilization. Especially in the application of photovoltaic greenhouses, farmers not only have access to a stable supply of electricity, but are also able to improve productivity, reduce costs, and even enhance the yield and quality of crops through power storage. So, how can PV energy storage systems improve profitability in agriculture? Let's explore this question specifically through some industry data and actual cases.

Advantages of photovoltaic greenhouses

Photovoltaic greenhouses are solar photovoltaic modules installed on the top of greenhouses, which can not only generate electricity for agricultural production, but also maintain a good temperature-controlled and humidity-controlled environment under different climatic conditions, further improving crop yield and quality. In addition, the PV energy storage system can store excess electricity during the day and continue to use it at night or on cloudy days, thus ensuring that agricultural production is not affected by fluctuations in power supply.

According to industry data:

1. Electricity cost savings

According to the Chinese Academy of Agricultural Sciences (CAAS), PV greenhouses can save about 30%-50% of electricity costs for agricultural production every year under the condition of effective utilization of light. For agribusinesses growing in greenhouses, PV systems can effectively reduce electricity expenses and directly improve operational efficiency.

2. Energy self-sufficiency

By installing PV energy storage systems, agricultural greenhouses can achieve more than 70% energy self-sufficiency, especially in areas with abundant light, the effect of power self-sufficiency is more obvious. This not only reduces the farmers' dependence on external power, but also avoids the operational pressure caused by rising electricity prices.

3. Long-term benefits

The system service life of PV greenhouses is usually about 25 years, with the cost of PV technology decreasing year by year, the payback period of enterprises has been shortened to 5 to 7 years, after which long-term stable income can be realized.

How can greenhouses realize efficient synergy through PV technology?

1. Intelligent system integration

Agricultural greenhouses use DC-coupled energy storage technology, with PV directly supplying power to irrigation and temperature control equipment during the day and storing excess power; at night, power is supplied through the energy storage system, which reduces the use of diesel generators by more than 70%.

Grid-forming PCS guarantees stable power supply, supports seamless switching with diesel generators, and the power supply interruption time is less than 20ms, which ensures no fluctuation in the growing environment of crops.

2. Modularized design adapts to multiple scenarios

Adopting lightweight flexible module, its load-bearing capacity is lower than 15kg/㎡, which is suitable for the transformation of traditional greenhouse structure and reduces the installation cost by 20%.

Configured with light-conducting PV panels, its light transmittance can be adjusted from 10% to 50% to meet the spectral requirements of different crops such as strawberries and flowers.

Multiple benefits of photovoltaic energy storage in agriculture

Photovoltaic energy storage system can not only provide stable power supply for agricultural greenhouses, but also bring multiple benefits as follows:

1. Optimize production environment

Through precise control of light, temperature and humidity, PV greenhouses are able to provide the best growing environment for crops under different climatic conditions, improving crop yield and quality.

2. Saving energy costs

Through self-generation of solar energy and electricity storage, agribusinesses can significantly reduce energy costs, especially in areas with high electricity prices, and the savings can be used for other agricultural inputs such as seeds, fertilizers and labor.

3. Enhancing agricultural sustainability

The application of photovoltaic greenhouses helps to reduce the use of fossil energy, reduce carbon emissions from agricultural production, in line with the trend of sustainable development, while enhancing the green image of enterprises.

4. Enhance market competitiveness of agricultural products

High-quality, high-yield agricultural products are more likely to gain a competitive advantage in the market, especially in the context of organic food and green agriculture is gradually favored, photovoltaic greenhouses can win more market share for enterprises.

Summarize

The application of photovoltaic energy storage system in agriculture can not only help farmers to improve their income, but also bring the double benefits of green environmental protection and sustainable development. Photovoltaic greenhouses have been upgraded from “experimental field” to “high-yield field”, and have become the standard equipment for modern agriculture to improve quality and efficiency. By installing photovoltaic greenhouses, agricultural enterprises can effectively save energy costs, improve crop yield and quality, while optimizing the production environment and improving market competitiveness.

If you also want to realize the green energy transition in agricultural production, photovoltaic greenhouse is undoubtedly a worthy investment choice. With the continuous development of photovoltaic technology and the gradual strengthening of policy support, the future of photovoltaic greenhouses will promote the green revolution of agriculture on a global scale.
