There are new modules on the market all the time with different wattage, mounting hole spacing, and frame dimensions. This chart gives an approximate guideline of how many modules fit on our mounts. If you find that you have a panel that has wattage specified in one size category, and dimensions that fit in a different size category, go with the mount that fits the dimensions of the panel.

To calculate square footage of your module, multiply frame width by frame height (in inches) and divide that by 144. This will equal your panel square footage. NOTE: millimeters divided by 25.4 = inches.

If you have any questions or want to be sure you are choosing the correct mount, please contact us.

Again, when placing an order, specify the mount model and the panel size (for example: UPM 6X Custom "B", or S-Rail Single "C"). Also, we will need to know the quantity and type of panels you will be using and to see the tech drawing on the spec sheet just to be sure the sizing is correct.

All mounting poles for post mounts are to be supplied by customer – note size required.
Post mounts are built to go on " A53 Schedule" pipe. This is the most common type of pipe in this country and is readily available in most steel yards. The Outside Diameter of the pipe is larger then the Schedule size indicates. The OD is the critical measurement for our sockets to fit correctly on the mounting post.
3" schedule pipe - 3 1/2" OD
4" schedule pipe - 4 1/2" OD
5"schedule pipe - 5 9/16" OD
6" schedule pipe - 6 5/8" OD
8" schedule pipe - 8 5/8" OD
10" schedule pipe - 10 3/4 OD
