Solar Photovoltaic Green Houses

Photovoltaic greenhouse

I. photovoltaic agricultural greenhouse brief introduction photovoltaic farmhouse is a greenhouse that integrates solar photovoltaic power generation, intelligent temperature control system and modern high-tech planting. The greenhouse uses a steel skeleton covering solar photovoltaic modules. At the same time, it ensures the lighting demand of solar photovoltaic power generation and the whole greenhouse crop. Solar photovoltaic power generation can support the irrigation system of greenhouse, supplement the light of plants, solve the heating demand of greenhouse in winter, raise the temperature of greenhouse, and promote the rapid growth of crops.

II. Advantages of photovoltaic agricultural sheds

Photovoltaic farmhouse is a new type of photovoltaic application mode. Compared with the centralized construction of large photovoltaic ground power stations, photovoltaic farmhouses have many advantages:

1. Effectively alleviate human-land contradictions and promote sustainable social and economic development.

The photovoltaic farmhouse power generation module uses the farmhouse roof, does not occupy the land, also does not change the land use nature, thus may save the land resources. In the case of large population growth, it can effectively reverse the trend of large reduction of cultivated land. On the other hand, photovoltaic projects in the original agricultural cultivated land construction, good land quality, conducive to the development of modern agricultural projects, the development of modern agriculture, support agriculture, conducive to the combination of the second and third industries and the primary industry. It can directly increase the economic income of local farmers.

2. Can flexibly create an environment suitable for the growth of different crops.

By setting solar panels with different transmittance on agricultural greenhouses, we can meet the light demand of different crops, plant various high value-added crops such as organic agricultural products and precious seedlings, and realize off-season planting and fine planting.

3. Meet the demand for agricultural electricity, generating benefits.

The use of ceiling power generation can meet the demand of temperature control, irrigation, light supply and other electricity consumption in agricultural greenhouses, and can also sell electricity to power grid companies to realize the income and benefit of investment enterprises.

A New Approach to 4. Green Agricultural Production

Compared with traditional agriculture, it pays more attention to the input of scientific and technological elements, management and the improvement of workers' quality. As a new mode of agricultural production and management, while promoting the popularization and application of regional agricultural science and technology, it will become the pillar industry of regional agricultural efficiency and farmers' income by realizing agricultural science and technology and agricultural industrialization.

III. Planting of photovoltaic agricultural sheds

1. Crops of high economic value

Photovoltaic farmhouses can focus on the development of organic vegetables, edible fungi and Chinese herbal medicine equipment production, moderate development of ornamental seedling planting, increase unit land output value and added value of agricultural products.

Most edible fungi do not need light or adverse reactions at the growth stage. Lentinus edodes, Pleurotus ostreatus, Pleurotus ostreatus and Flammulina velutipes can be planted.

According to the different requirements of vegetable light intensity, it can be divided into vegetables that need strong light, vegetables suitable for medium light and vegetables that bear weak light. Weak light-resistant vegetables are mainly celery, asparagus, spinach, ginger, leek, lettuce, dandelion, cabbage, black fungus and so on.

Negative, Yin-resistant Chinese medicine has Panax quinquefolium, Coptis, Codonopsis, Ophiopogon japonicus, Radix Isatidis, Atractylodes macrocephala, Pinellia ternata, Gastrodia elata, Ganoderma lucidum.

Can cultivate shade-tolerant seedlings, potted plants, flowers and so on in the greenhouse.

2. Can be developed into sightseeing agriculture.

Make full use of good transportation and location advantages, make full use of agricultural production and ecological environment resources, rely on ornamental seedlings and other ecotourism resources, cooperate with the development and construction of agricultural tourism resources such as organic vegetables, produce and acquire agricultural tourism resources, develop tourism projects in various forms, such as sightseeing, leisure and experience, and form characteristic and large-scale sightseeing agriculture.

IV. Architectural form

The construction of photovoltaic farmhouse is mainly integrated thin film photovoltaic greenhouse (flexible connection between power generation module and steel skeleton), original greenhouse professional transformation and so on. Generally speaking, the new shed is built according to the comprehensive building, as shown below.

Greenhouse generation module can be divided into thin film module, polysilicon module and monocrystalline silicon module. Compared with ordinary greenhouse, the steel frame structure of photovoltaic shed is more complex and the cost is relatively high.
