Besides some advantages of large scale and quick deployment of this farm model combined with solar power, there are also many questions about how to both make solar power and combine agriculture below and deploy everywhere like the rooftop solar power model. Today Ngu Thuong (using the model of growing straw mushrooms in greenhouses) will answer this question for readers to refer to further.

Decision 11 of the Prime Minister has created a very good mechanism to promote the rapid development of the solar power industry in Vietnam. With the mechanism of selling excess electricity to the grid, many households, businesses, and factories have installed solar power for both use and sale. There is a model that both uses and sells electricity, which is high-tech agricultural farms, below is farming and above is covered with solar panels, both producing electricity to serve the farm's own needs and selling electricity to the grid to create additional supply for the national grid.

Unlike ground-mounted solar power, which only produces and sells electricity to the grid, solar power combined with high-tech agriculture will create dual agricultural benefits below such as growing mushrooms, vegetables or suitable plants, or raising high-yield cows, chickens, pigs, crickets..., in addition, the project owner can develop it themselves or combine with an agricultural company to invest profitably from the existing infrastructure assets of roofed houses.

In the combined models, Ngu often chose one of the energy stations to test the indoor Straw mushroom growing model. This method has many conveniences and advantages. Compared to producing straw mushrooms outdoors, growing straw mushrooms indoors can be done all year round without fear of weather influences, controlling temperature and humidity, helping mushrooms grow well, achieving high productivity, ensuring clean, high-quality products.

In particular, growing straw mushrooms indoors can also proactively produce and sell on holidays, New Year and the full moon day of the lunar month, getting a higher price than normal days from 6,000 - 10,000 VND/kg. In addition, the remaining straw and cotton after harvest will be collected, composted, and sold to households growing ornamental flowers, contributing to increased income.

Straw mushrooms

On average, each mushroom growing house is built with iron columns, covered with tarpaulin to suit the available area of each power station, the built area is from 20 - 100 m2. The benefit of growing straw mushrooms indoors is to avoid the influence of the weather when the temperature is too high, the humidity is low, the rain is heavy... the output reaches an average biological conversion index of 20% of the raw materials. Since then, the productivity in a 30m2 room has reached about 90kg. With the lowest selling price of 60,000 VND/1kg of mushrooms, it will ensure a good income with this combined model.

Straw mushrooms are an industry that requires high technology, a rich market, and is almost constantly in a situation where demand is greater than supply, so this is also the reason investors should choose.
