Solar mounts are used to attach your PV
panels to your roof. There are also pole mounts for solar panels but here we will be
discussing the bracket and rail mount systems used in roof based solar installations
(solar roof mounts).
Choosing the right solar mounts is an important
part of solar power installation since this is the main structural support for your PV panels.
When deciding on which solar roof mounts to use, you
must take into consideration size, utility, affordability and convenience.
Knowing your solar mount options plus the benefits of each one will help you decide which solar
panel mount option is right for you.
Types of Solar Roof Mounts
There are three main types of solar mounts for roof top installation: Flush
mounts, roof/ground universal solar mounts and the slightly more user friendly mount rail
Flush solar roof mounts are normally used with
smaller solar systems and cannot swivel or change angle once installed. These solar
panel mounts consist of metal brackets that support each side the solar panel, elevating it
several inches from the roof.
They don't consist of much actual hardware which not only makes them the most
affordable choice but also easy to install.
Make sure there is at least at 2-4 inches of space
between the roof and the bottom side of the solar panels for circulation and
Although flush solar PV mounts are very affordable and easy
to install, they are best suited for use will smaller solar arrays that require no flexibility
in their orientation (angle).
Roof / Ground Universal Solar
Roof / ground universal solar mounts are used with
larger solar photovoltaic systems and can be mounted on both the ground and
These solar roof mounts are made up of a grid-like system of multiple
supports and are typically much more bulky than flush solar roof mounts, thus provide
much more support for longer, wider and heavier solar panels.
Many of these solar mounts have the ability to swivel or
change angle although some are harder to adjust than others. There are even some of these
solar roof mounts that you can program to change the tilt of your solar panel with the
movement of the sun for an increase in solar power production.
Since there's more hardware in the construction of these solar roof
mounts as well as more support and functionality they are also more expensive.
These solar roof mounts have also been known to be harder to install on rooftops
especially if there's strong wind, however if you have huge solar panels roof/ground universal
solar mounts may be your only choice for secure support.
Solar Mount Rail
Solar mount rail systems are like universal solar
panel mounts but typically much more flexible, versatile and easier to install and
adjust. These solar roof mounts can be used for flat roof installations or for tilted
When the tilt mounts are installed horizontally it is known as horizontal
mode, and when they're vertical, it's called landscape mode.
Solar mount rail systems come in a variety of sizes and styles the most common
involving bolting a rail system to your roof first and then attaching the panels to the rails.
The type of solar mounts you choose for your roof mount solar installation
will depend on your location, environment, roof condition, budget and individual needs and
However, most solar residential systems use the flush mount brackets on flat roofs,
the mount rail system on sloped roofs as well as roof/ground universal solar mounts, but less
