What is agricultural photovoltaic greenhouse?

For a new word “photovoltaic greenhouses”, it is the combination of two completely different industries. Photovoltaic power generation belongs to the new energy industry, while greenhouses belongs to one of the planting industries, which are called indispensable facilities in agriculture. It is mainly to solve the problem of out-of-season vegetable planting in winter, and make use of the thermal insulation and light entry of the greenhouse, so as not to affect the production of winter vegetables. Making money from photovoltaic power generation and making money from growing vegetables in greenhouses do not affect each other, which is why photovoltaic greenhouses appear. It can also be understood that this is the definition of photovoltaic greenhouse.

How to design photovoltaic greenhouse?

Greenhouse need light, photovoltaic power generation also needs light, the reason why they can combination is also because light, and the contradiction between them is also because of light. Take the most common example, in the same solar greenhouse, it is necessary to meet the growth of crops and meet the maximum amount of photovoltaic power generation, the balance between the amount of photovoltaic panels and the light transmission of the greenhouse, among which the most important design is to make the front room as a whole large plane, so that the lighting is better, also suitable for vegetable planting and power generation. In order not to interfere with the photosynthesis of the vegetables in the greenhouse, photovoltaic accounted for one-third, the rest for light transmission.

Does design influence the insulation of greenhouses?

Take solar greenhouse as an example, it is mainly used for off-season vegetable cultivation in winter. The key to the greenhouses can be planted in winter is that they have very good insulation in winter. Such design guarantees photovoltaic power generation and daylighting of greenhouses, but ignores the problem of thermal insulation. Usually there have insulation quilt in the normal design of the front room of a solar greenhouse, but this design don’t consider for insulation quilt. For winter planting, the reduction of thermal insulation, can only grow more cold resistant vegetables, the income will be reduced. For the vegetable industry, winter vegetable prices are the highest.

What are photovoltaic greenhouses suitable for planting?

Photovoltaic greenhouses are suitable for growing edible fungi. Under normal circumstances, edible fungi do not need light during their growth process. If necessary, additional shading measures may be added, such as oyster mushroom, shiitake mushroom, enoki mushroom and these common fungi can be planted. Except growing crops, there can also be farming projects, such as small and medium-sized livestock, which can make money without affecting power generation. There is not enough light under photovoltaic panels, so it’s suitable for shade-loving plants.
