similarity 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
Difference between Solar Racking with Rails and Without Rails
- Mounting compoment qty is different.
- Rails add additional weight to the roof which could mean older/less engineered buildings may not support the additional load
-
Minirail solar system design is sleeker, less noticeable design
-
Less weight on rooftop means it may be more compatible with older/less engineered buildings
