Solar C Section may refer to the Solar C brise soleil, a solar shading system that reduces heat and glare. It’s made of aluminum and can be mounted above or in front of windows. The louvres can be mounted around curves and corners, and the system can be installed at different angles and dimensions. C-section may also refer to C-section purlins, which are used in solar module mounting solutions. C-section purlins made of ZINCALUME steel are more resistant to corrosion and can last up to four times longer than galvanized steel.
