4 Frequently Asked Questions about “How many rails are needed for 6 photovoltaic panels - Inala Strategic Solar”
How many rails does a solarmount need?
The 156-inch SolarMount rail (part number 300011) is my best bet. Each row of modules requires two rails (top and bottom). This system, which has two rows of modules, requires four rails. Further, since I will be splicing two 156" rails in order to reach the required 294.6" rail length, I will need a total of eight 156" rails.
How many inches of rail do I Need?
Adding eight inches for mid-clamps and two inches for end-clamps results in a minimum of 294.6 inches of rail. Going back to the Unirac Master Component List, you can see that rails come in predetermined lengths. I will connect two smaller rails to create the needed length via a splice (See Splices in section 2).
How many rails do I need to splice a module?
Each row of modules requires two rails (top and bottom). This system, which has two rows of modules, requires four rails. Further, since I will be splicing two 156" rails in order to reach the required 294.6" rail length, I will need a total of eight 156" rails. 2) Splices (Unirac Master List page 16)
How do I calculate rail size?
Please refer to the modules oriented in portrait as seen on the image below. To estimate total rail size, simply multiply the module width (if in portrait, or the module length if in landscape) by the number of modules in a row. Then add one inch between each module and two inches at each end of the modules for the mid and end clamps, respectively.

How Many Mounting Brackets Does a Solar Panel Need?
Some systems use shared rails or interlocking brackets between panels, reducing the total number needed. Others follow a one-panel-per-rail approach that may require more brackets overall.
