Photovoltaic Agricultural Power Station System Case

1.Project main positioning

A photovoltaic agricultural industrialization demonstration base will be built in the planned area, covering an area of about 2,000 mu. It is a comprehensive demonstration park integrating agricultural production, technology, ecology, sightseeing and other functions, with the development of photovoltaic industry, giving priority to the development of modern agriculture, guided by the government and operated by enterprises, and built and managed with the concept of industrial park, with the goal of promoting agricultural modernization and increasing farmers' income, based on modern technology and material equipment, implementing intensive production and enterprise management, and integrating agricultural production, technology, ecology, sightseeing and other functions.

After completion, the project will become a modern photovoltaic agricultural industry demonstration base with advanced provincial facilities, reasonable agricultural function system design, and representative and exemplary. This project intends to use Israel's advanced greenhouse technology, combined with local climate characteristics, and position the product as a production base for local high-end agricultural products, driving the production of high-end agricultural products (including high-end organic fruits and vegetables, fungi, and medicinal materials) in the local area and radiating to the surrounding area within a radius of 300 kilometers, and even becoming a production base for high-end, cross-regional economic crops.

2.Overall design

Plan layout: 90 multi-span greenhouses and 75 multi-functional greenhouses will be built, with the overall positioning of producing organic, high-end, high-value-added fruits, vegetables, fungi and other economic crops.

Total capacity: 50MW.

Multi-span greenhouses: Each greenhouse covers an area of 6000㎡ (excluding the front and rear road area of 5110 ㎡), with an installed capacity of 492.8kW; the greenhouse roof is arranged in a north-south direction, and photovoltaic modules are arranged on the south roof. The modules are recommended to use monocrystalline silicon 280W high-efficiency modules;

Multi-span greenhouses are mainly used for intercropping or mixed planting of different crops with different temperature requirements in different seasons. According to the length of the growth period of different crops, reasonable connection and intercropping are carried out. Three-dimensional cultivation of vegetables with different light requirements makes full use of the space and light characteristics in the greenhouse to give full play to the production potential of limited ground.

Multifunctional shed: Each shed covers an area of 3000 ㎡ (excluding the front and rear road area of 1425 ㎡), with an installed capacity of 73.92kW; in the multifunctional shed, the components are arranged on the roof of the mushroom house, and the components are recommended to be monocrystalline silicon 280W high-efficiency components.

Multifunctional shed belongs to intelligent photovoltaic agriculture. The front of the shed is used as a winter warm shed for planting plants, the back of the shed is used for factory-based edible fungi breeding, and the roof of the shed is used for power generation. One shed has three uses: energy circulation, water saving, land saving, and energy saving.
