There are three commonly used steel structures for supporting solar PV power system.

We present the three most commonly-used types for large-scale installations such as the SolarNova tenders in Singapore.

Comparison of Common Solar Structures

Basic Fabricated Steel

Common Steel for Solar PV Structure
- Easy access to raw materials and fabricators.
- High flexibility in design.

- Design is seldom optimized; economy of materials often result in mounting rails that can only support 3 panels.
- Inconsistency in quality during large quantities due to reliance on manual fabrication techniques.

- This system is suitable for large-sized installations if a reliable steel fabricator is available.

Struts System

Struts as Solar PV Structure
- Familiar system for M&E contractors.
- Easy access to materials and accessories.

- Customizing of design results in higher costs from the use of more accessories and materials.
- Shortage of connecting accessories and brackets often result in lost productivity on site.

- This system is suitable for mid-sized installations.

Lightrus Solar Structures
Lightrus Solar PV Structure Pros:
Custom designed to optimize output.
Value engineering can be applied to optimize output.

Cons: More costly on small installations.

Comparing between the basic quality of Lightrus Zincalume solar structures and the commonly-used Struts system, customized hot-dipped galvanized structures from both local and overseas markets(HDG), the zincalume structures by Lightrus are more cost-effective and outperform hot-dipped galvanizing (HDG) in outdoor applications.
