Solar Structure Installation
Installing solar panels is not simply about placing panels on a roof or open ground. A properly designed and installed solar mounting structure is essential for supporting the panels, maintaining the required orientation and tilt, and protecting the installation against wind and other environmental loads.
For project owners, choosing the right structure and ensuring proper installation can have a direct impact on the safety, durability and long-term performance of a solar project.
From rooftop solar systems and industrial installations to ground-mounted plants and solar car parking structures, every project has different structural requirements.
SmartCube India specializes in the manufacturing and installation of solar mounting structures for rooftop, ground-mounted, elevated, tin-shed, solar car parking and customized applications.
This guide explains the major steps involved in solar structure installation and what project owners should consider before, during and after installation.
What Is a Solar Mounting Structure?
A solar mounting structure is the supporting framework used to securely install solar panels on a particular surface.
Its main functions are to:
- Support the weight of solar panels
- Maintain the required panel orientation
- Provide the appropriate tilt angle
- Resist wind and environmental loads
- Keep panels securely positioned
- Provide structural stability
- Allow suitable access for inspection and maintenance
The structure can be installed on different surfaces depending on the project, including RCC rooftops, metal or tin roofs, open ground and parking areas.
SmartCube India manufactures structures using materials such as hot-dip galvanized steel and aluminium, depending on project requirements. Its website specifies customizable tilt angles and project-specific structural design.
Step 1: Understand the Solar Project Requirements
Before manufacturing or installing the structure, the project requirements need to be clearly defined.
Important information includes:
- Solar plant capacity
- Number of solar panels
- Panel dimensions and weight
- Roof or ground conditions
- Available installation area
- Desired panel orientation
- Required tilt angle
- Structure height
- Wind conditions
- Environmental exposure
- Access requirements
- Maintenance requirements
A residential rooftop system may require a completely different structure from a large industrial rooftop or MW-scale ground-mounted project.
Therefore, the structure should be designed according to the actual project rather than using a generic solution.
Step 2: Conduct a Site Assessment
A proper site assessment is one of the most important stages before installation.
For rooftop projects, the assessment should consider:
- Roof type
- Roof dimensions
- Roof condition
- Existing structural capacity

For ground-mounted projects, the assessment may include:
- Available land area
- Soil conditions
- Site accessibility
- Foundation requirements
- Ground levels
- Drainage
- Wind exposure
- Panel arrangement
SmartCube’s existing engineering workflow highlights site assessment, wind conditions, roof type, available space and structural requirements before finalizing the solar structure design.
Step 3: Check Structural and Load Requirements
The solar structure needs to support more than the weight of the panels.
Engineers may need to consider:
- Dead load
- Solar panel weight
- Wind load
- Applicable live loads
- Structure weight
- Foundation loads
- Environmental conditions
- Installation-specific forces
Wind load is particularly important because solar panels can experience significant uplift and lateral forces during strong winds.
For industrial rooftops and large solar projects, structural calculations should be carried out according to the project’s engineering requirements and applicable standards.
SmartCube’s website states that its solar structures are designed with consideration for wind-load resistance and references IS 875 and IS 800 in its design specifications.
