Solar PV Module & STEEL FRAME Overview
PV Module Steel Frame Overview
-
The PV module frame that uses aluminum (AL) frame panel configuration is the common practice
-
NEOTEC has developed STEEL FRAME alternatives.
Solar STEEL FRAME Development
We developed a STEEL FRAME using the roll-forming process.
Roll forming enables cost competitiveness for PV STEEL FRAMES through precise, high-volume production while ensuring high quality.
Roll-forming is applied for accurate, mass-production of steel frames with high quality assurance.

Business Feasibility of Solar STEEL FRAME
High compatibility & eco-friendly parts
Steel frame components can be applied to existing AL frame PV production lines (lower capital investment).
Interchangeable shape & size: Same shapes and sizes as existing AL frames enable high compatibility with existing AL hardware (reducing construction costs).
Material substitution flexibility: Depending on AL vs. STEEL price fluctuations, customers can choose materials to reduce product cost.
Lower CO₂ emissions: Steel frame reduces CO₂ emissions compared to AL frames, aiding compliance with carbon regulations and contributing to carbon neutrality.

Cost competitiveness: Steel materials can achieve better price competitiveness.
POSMAC 3.0 substrate provides superior corrosion resistance, enabling omission of extra surface treatment and therefore cost savings.
Benefits Using POSMAC 3.0
Lower volatility in steel pricing vs aluminum
High-strength steel enables high-rigidity frame design
