Sunpark Greenhouse
The Sunpark Greenhouse Systeem has been developed for both renovation and new construction of greenhouses. The self-supporting roof structure with integrated solar panels is mounted on an existing or new greenhouse gutter.
By using standard, widely available photovoltaic (PV) panels, the installation can be fully tailored to the client’s requirements. Integrated ventilation in the roof ensures effective cooling of the solar panels. Wear and malfunctions are minimized as all electrical components are installed in a dry environment. The roof structure is considerably stronger than a traditional greenhouse roof, reducing the risk of damage, lowering maintenance costs, and increasing overall safety.
The Sunpark Greenhouse Systeem contributes significantly to the reliability of the building and the optimal performance of the PV installation.
Standards
The Sunpark Greenhouse Systeem is designed in accordance with European standards and the Dutch regulations under the Besluit bouwwerken leefomgeving (Bbl). For greenhouses and garden centers, NEN-EN 13031 applies. For other applications, such as parking canopies, carports, warehouses, and sheds, the Eurocodes (EN 1990–1999) form the basis for structural design.
The Eurocodes require higher snow and wind load resistance and risk factors. While the Sunpark Greenhouse Systeem can serve as a roof solution, standard greenhouse gutters present limitations. This is why the bending stiffness of the Omega gutter is five times higher than that of a typical greenhouse gutter.
Within the context of greenhouses and garden centers, the Sunpark Greenhouse Systeem provides substantial reinforcement of the roof structure. For applications outside the scope of NEN-EN 13031, the Sunpark Omega Systeem offers a suitable solution to meet the applicable standards.
Note: For projects outside the Netherlands, or for non-standard loads, spans, or greenhouse configurations, the structural design must always be verified and approved by a locally certified structural engineer.
Solar Panels
The Sunpark Greenhouse Systeem is adapted to the standard dimensions of greenhouses and PV panels. Venlo-type greenhouses with steel gutters typically have roof spans of 3.20 m or 4.00 m. Commonly used PV panels have the following dimensions:
|
Roof Span |
Panel Size |
Power |
|
3.20 m |
1762 × 1134 × 30 mm |
± 460 Wp |
|
4.00 m |
2278 × 1134 × 30 mm |
± 600 Wp |
To integrate the panels effectively, the roof pitch of the Greenhouse Systeem is slightly steeper than a traditional greenhouse roof. Alternative configurations, such as smaller panels or larger roof spans, can be customized to meet project-specific requirements.
Applications
The Sunpark Greenhouse System is suitable for both renovation and new greenhouse construction.
In production greenhouses, light transmission can be maintained by using (semi-)transparent solar panels. In addition, a closed cultivation environment can be created based on the principles of Circular Indoor Farming. When properly implemented, this results not only in positive energy production, but also in CO₂ consumption and up to 95% reduction in water use for crop production.
If you do not wish to modify your cultivation environment, please note that a roof with solar panels allows less light transmission. For many crops this is not desirable, but in non-cultivation environments it can be an advantage due to reduced heat load. This applies, for example, to processing areas, logistics, storage, and technical spaces. Applications such as caravan storage also benefit from a less transparent roof.
In such applications, the Sunpark Greenhouse System provides structural reinforcement of the roof while minimizing the risk of glass breakage and damage.
