Semi-Slope Heat Storage Solar Greenhouse

Ruize produces the Semi-Slope Heat Storage Solar Greenhouse in China as a manufacturer serving cold-climate agricultural projects and overseas greenhouse orders. The design follows the traditional solar greenhouse heat-storage principle: the front slope admits sunlight during the day, while the rear wall and rear slope absorb and retain heat for gradual release after sunset.

This passive heat-storage structure is intended to reduce the speed of nighttime cooling and help maintain a more stable growing environment when outside temperatures fall. It is particularly suited to areas with cold winters, frequent frost, snow and significant differences between daytime and nighttime temperatures.

Rear Wall and Rear-slope Thermal Storage

The rear section is the key heat-retention part of the greenhouse. A solid insulated rear wall works together with a high-density insulated rear slope to store daytime solar heat and release it gradually during the night.

• Solid insulated rear wall for heat retention
• High-density insulation layer at the rear slope
• Daytime solar heat storage
• Gradual nighttime heat release
• Reduced day-night temperature fluctuations

This structure helps protect crops from sudden nighttime cooling and is intended for overwintering production where maintaining suitable temperatures is important. In colder areas, additional thermal blankets or heating equipment can be added according to crop requirements.

Front Slope Designed for Winter Light

The front roof uses an inclined light-receiving surface rather than the curved form of an arch greenhouse. Its angle can be adjusted according to the latitude of the installation site, helping make better use of lower-angle winter sunlight.

The front slope and rear thermal structure work together: sunlight enters through the front covering during the day, while the rear section helps retain part of the accumulated heat after sunset. This makes the greenhouse particularly suitable for winter-growing conditions in high-latitude and cold regions.

Prefabricated Galvanized Steel Frame

The main frame uses round or oval steel tubes with acid cleaning, hot-dip galvanizing and passivation treatment for corrosion protection. The finished components are prefabricated at the factory and connected on site using standardized fittings.

This assembly method avoids the need for professional welding during the main installation process. For overseas projects, the modular structure can simplify installation and reduce dependence on specialized construction labor.

• Round or oval steel frame options
• Hot-dip galvanized corrosion protection
• Factory-prefabricated components
• Modular connection and assembly
• No on-site welding required for the main structure

Equipment Can Be Added Around the Crop

The greenhouse can be fitted with supporting systems according to the crop, climate and operating requirements. The original configuration supports the following options:

• Electric thermal blanket rolling system
• Top and side ventilation film openers
• Air circulation fans
• Water and fertilizer integration equipment
• Winter heating equipment
• Rainwater drainage gutters
• External shading system

These systems can be selected according to the actual growing conditions rather than requiring every greenhouse to use the same configuration.

Configuration Reference

Suitable Crops and Applications

The greenhouse is primarily intended for overwintering cultivation in cold regions. Its structure is especially relevant to crops that need protection from low temperatures during winter.

• Winter vegetables in high-latitude regions
• Strawberry growing and picking farms
• Fruit and vegetable nursery bases
• Small and medium-sized family farms
• Overwintering medicinal plant cultivation
• Off-season leafy vegetable production
• Connected agricultural demonstration projects

For areas with mild winters and no regular frost, the heat-storage advantage of this greenhouse may be less important. In such climates, a different greenhouse structure may be more suitable.

Flexible for Different Growing Sites

The greenhouse dimensions can be adjusted according to the available site and planting plan. Span, ridge height, overall length and rear-slope insulation thickness can be modified as part of the project configuration.

Larger-span layouts can also be considered where internal working space and agricultural machinery access are required. The actual structure should be designed according to the site, crop arrangement and equipment layout.

Export-ready Modular Delivery

The frame is divided into sections before packing, allowing the components to be organized for container transportation. This modular format also makes unloading, handling and on-site assembly more manageable for overseas agricultural projects.

Ruize can provide construction drawings, step-by-step installation videos, installation information and remote technical support. Original steel frame components, film and connection fittings can also be supplied for later maintenance and replacement.

Maintenance and Long-term Use

The galvanized steel frame is intended for long-term outdoor use, with the supplied product information indicating a service life of more than 10 years under normal conditions. Routine checks should focus on the frame, connection fittings, covering, ventilation components and thermal-control equipment.

For winter-use greenhouses, inspection before the cold season is especially important. The condition of the thermal insulation, covering and ventilation system can directly affect the internal growing environment.

Frequently Asked Questions

Can the rear insulation layer be increased for colder locations?

Yes. The rear wall and rear-slope insulation thickness can be adjusted according to the local winter temperature and crop requirements.

Is a semi-slope heat-storage greenhouse suitable for warm, low-latitude regions?

It is more suitable for cold and high-latitude regions where winter heat retention is needed. In warm, frost-free areas, the thermal-storage structure may not be used to its full advantage.

Can the front-slope angle be adjusted for different latitudes?

Yes. The front-slope angle can be planned according to the latitude of the project location to improve the use of available winter sunlight.

Does the customer need to source the rear wall materials locally?

Ruize can provide the rear-wall construction drawings and insulation material arrangement. Concrete and insulation materials can be sourced locally where appropriate, which can simplify the transportation of bulky construction materials.

Can the greenhouse accommodate agricultural machinery?

Yes. Larger-span configurations can be planned to provide wider working paths and usable internal space. The final dimensions should be based on the machinery size and the actual operating layout.
