What is Rail Solar Mount Systems and Rail-less Solar Mount Systems?

AISINEE compares rail solar panel supports and rail-less solar mounting rack solutions available for residential shingle rooftops and identifies the pros and cons of each. AISINEE offer a variety of rail solar mounting solutions that allow us to customize our system designs to best meet customer’s aesthetic and financial needs. However, we realize pv rail mounting isn't for everyone. So take a look at the comparison below. 

Similarities Between Solar Racking with Rails and Without Rails

• They can be integrated when the roof is first installed or later after the roof is already on the house
• Roof warranties (if one exists) are typically not impacted by either mounting method
• Both should be installed by professionals - with proper installation the system will protect the rooftop and keep the roof watertight
• The price variation is a few cents per kW, a very small proportion of the overall system cost
• Both types integrate with inverters similarly

Standard Rail PV Mounting System:

This method uses a flashing to attach onto the existing rooftop. The flashing is similar to what would be used for a standard roof vent. An “L” foot or support component is then fastened to this flashing and holds the aluminum/steel rail 2-4 inches above the rooftop, upon which the solar panels are mounted.

Rail-less Mounted Solar:

This more of a low profile mounting method. Systems typically use multiple attachment points on the rooftop and attach to each panel individually, eliminating the need for rails.
