Solar panel mounts are used to secure your solar array to a surface and can also be used to optimize your panel’s energy production through its angle and direction. The type of solar mounts that would be required for an array are completely dependent on the specific surface it's being attached to.
What is the best distance between the roof rack rails? In this video, he says you have to measure a distance between the holes in the solar panel, and use that distance in order to space apart the rails on the roof.
Figures C-E specify the maximum spacing between rail supports for tile or tin roof installations. Maximum panel dimensions are 1650mm x 1000mm and weight 22kg. For other panel sizes, refer to the “DPASolar Racking Worksheet” (Excel). Note that Figures C-E assume F5 pine or better roof construction.
L-feet and standoffs are the parts that connect your rail to the roof. The number of L-feet depends on how sturdy of a system you need. In conditions where there is no significant snow load or high wind speed, L-feet spacing of 5 ft or closer can be necessary. The harsher the conditions, the more L-feet connections and roof penetrations are .

6 FAQs about [Requirements for spacing between horizontal bars of photovoltaic panel brackets]
How far off a roof should a solar system be mounted?
Most residential rooftop PV arrays are mounted between 4” and 6” off the surface of the roof and are parallel, or nearly parallel to the roof surface. A system on a flat roof will be mounted at a slight angle in most cases to prevent pooling of water on the surface of the solar panels.
What angle should a solar panel mount face?
This is usually at a 30-degree angle and should face south or southwest. Solar panel mounts can be completely customized to facilitate the effective positioning of the attached solar panel array to meet these parameters.
How do I install a solar PV system?
Install a mounting system for solar thermal or solar photovoltaic panels. Consider the roof type (material and slope), weatherproofing, installation convenience, and wind and snow loadings. Choose an appropriate racking and mounting system for the type of PV module, and install the system along with needed flashing and seals.
Is a PV array parallel to a roof?
5. The PV array is flush mounted (parallel to roof) Roof installations of PV arrays that are not parallel (or nearly parallel) to the roof structure present unique wind and snow loading issues that may need further review by a design professional.
How far off a roof should a parallel-to-roof array be?
For parallel-to-roof arrays, the distance between the roof surface and underside of module needs to be limited to 10 inches to control wind uplift pressures and take advantage of the “Kopp factor.” Wind tunnel research (Stenabaugh et al, 2014) shows that this reduction factor is 0.80 or less for arrays up to 10 inches off the roof.
Do solar panels need mounts?
Solar panel mounts are a common component of almost every solar panel array. Although there are newer solar panel technologies coming out that do not require mounts, such as the Lumeta solar module that are being developed, the majority of solar panel arrays on the market and the ones already installed will require this feature.
