Solar Panel Rail Spacing

As explained in the balance of systemsection solar racking is used to hold modules in place.

Solar panel rail spacing.

Then the distance between the next rail for the next row of modules would simply be about 6 6 12 plus maybe an extra half inch to an inch for a gap between the top row and the bottom row of modules. You have already figured out where the roof supports are and that your roof can hold the added weight of the panels. Rails are supported by individual mounts base mounts that may be spaced at 4 feet or more along the rail. Since the panel is 41 6 that means that the distance between both rails holding the same module would be 41 6 6 6 29 6.

Good write up does this equation for determining row width hold good for single axis tracked panel rows which run north south. In a typical flush mountsystem on a residential rooftop each row of modules sits astride two rails. Therefore load from solar panels including snow on panels will be concentrated at the base mounts. If the rows are long multiple rails are spliced together to cover the distance.

Applying this height difference becomes 32 28 32 module spacing 105 minimum module spacing 75. Thus if foot spacing is 1200mm the rail end over hang can be up to 600mm. For most home arrays you ll be using rails that are either 136 or 162. Australian standards require a gap of at least 5 cm between roofs and solar panels.

With proper installation a sturdy mount secures your panels in harsh weather and protects your investment. Unirac is north america s leading manufacturer of solar pv mounting systems. At this point of the installation you are now ready to pick the rails. In this case two feet can support a rail of as much as 2400mm 1200mm between the feet and 600mm of overhang at each end.

Solar panels are often supported on rails installed perpendicular to across or parallel to rafters. Mounts are used to attach solar panels to the roof ground or another surface on your property.

The panels in each row tilt maximum 55 55 towards the sun at sunrise and sunset. However in urban areas panels are generally not allowed to extend more than 10 cm from the surface. As a typical solar panel is around 4 cm thick this only leaves a 5 to 6 cm space in which to work.
