Solar Structure
Choosing the right panel structure is vital for maximizing space, efficiency, safety and aesthetics.
Panel Structure Comparison
| Factor | Galvanized Iron (GI) | Aluminum (Al) | Stainless Steel (SS) |
|---|---|---|---|
| Corrosion Resistance | Good (zinc coating) | Excellent | Superior |
| Strength & Load Bearing | Highest | High | Extremely High |
| Weight | Heavy | Very Light | Heavy |
| Cost (Relative) | Lowest | High | Highest |
| Life Expectancy | 20–25 years | 25+ years | 50+ years |
RCC Roof Mounting Structure
RCC mounting structures are used to install solar panels on concrete rooftops and are a standard choice for residential and commercial buildings. Keeping panels close to the inverter reduces wiring needs and DC losses.
ProsLower installation cost, easy maintenance, useful roof utilization and added roof protection.
Important precautionsRoof penetrations must be sealed correctly, orientation should be suitable, and the area should remain shadow-free.
Material selectionUse suitable isolation and fasteners when mixing metals to reduce galvanic corrosion risk.
