How to choose the proper type of solar greenhouse in your project

In the modern times, Growing vegetables and plants for people is a very productive hobby and is considered a great supplemental livelihood. Besides, it is a good way to earn extra income by producing high-valued crops. As a result, greenhouses have become very popular, widely used both in agriculture and household today.

In most cases, agricultural crop production depends on two main factors: solar radiation and climate. Plants need solar radiation for photosynthesis, and the interior environment (temperature and humidity) must match the plants requirements. Technically speaking, the main operation principle of a solar greenhouse lies in accumulation and storage of solar energy (sun radiation) during daytime and gradual release of the energy (heat) during the night. In that regard, solar greenhouse have many distinctive features, such as collecting the maximum amount of solar radiation during the day, efficiently storing the heat collected from sun radiation during the day, releasing this heat to the interior of the building during the night, reducing heat losses by insulation of the whole greenhouse and so all. In addition, solar greenhouse has a very bright future, especially given the amount of concern over the global energy crisis and climate change (no CO2 emission during horticultural crops winter production), as significant energy savings can be accrued from switching to solar greenhouses.

At present, solar greenhouses have four major categories according to their structural characteristics: the ordinary style, semi-underground style (0.5m–0.9m underground), multiple gutter-connected style, and double-arched style. Specifically speaking, the ordinary style is still the most used version, with about 95% of the extant solar greenhouses using this structure. The semi-underground style has a shading problem in winter and waterlogging in summer. The multiple gutter-connected greenhouse style is very roomy, which is often correlated with poor heat preservation if it is not heated. This type of greenhouse is used on a very small scale. The double-arched style is expensive to build; however, its good insulation is an attractive attribute. This model is at the beginning stage of technical optimization and extension to end users in the Chinese market.

In recent years, people opt for glass greenhouses over plastics primarily because of clarity and transmission. Glass panels allow more light in comparison to polycarbonate and it won’t fade over time. This means a higher potential for photosynthesis, as well as greater heat absorption. Glass is inert, long-lasting, UV resistant, non-combustible, and easy to maintain. And a passive solar greenhouse has been widely used in many applications because it is a greenhouse heated entirely by sunlight, with no additional fuel based heating. Passive solar greenhouse absorbs as much as possible solar energy (sunlight during the day) in the winter season for the following gradual emission of accumulated solar energy for heating purposes.
