Your guide to solar panel mounts in 2023
In recent years, buying solar panels has become easier, due to the availability of reviews comparing solar panels, solar installers, and solar inverters. However, it remains challenging to find helpful information on solar panel racking and mounting systems.
Solar panel mounts are integral to your solar panel system. There are many variations available for what you need, no matter your roof style or ground mounting system necessities. Your solar installer will know the best option to get the most use out of your solar system.
In this article, we will provide an expert review of solar panel mounting solutions, highlight the top three solar panel mount brands, and discuss the pros and cons of rooftop solar systems versus ground-mounted systems.

What is solar panel mounting and racking?
Solar panel mounts and racks are equipment that secures solar panels in place.
Mounting allows the panels to be adjusted for optimal tilt, which can be based on latitude, seasons, or even time of day — to ensure maximum solar energy production. The most common locations for mounting are on the roof, using solar roof mounts, or on the ground with ground-mount options.
Mounting systems are the metal racks that hold up solar panels either on roofs or on the ground. Image source: PV Solar First
In terms of cost, mounts and racking typically account for about 10% of the total cost of an average solar system. For example, if your solar system cost 10,000, the racking system portion would be about 450,000 of the total cost.
The price will depend on the type of racking you use, the amount of equipment needed, and labor costs for installation.
The most common technique of module mounting is using a solar panel mounting bracket. Mounting brackets are heavy-duty equipment, usually made from stainless steel or aluminum. All solar racking and mounting products, whether for the rooftop or ground, must meet strict guidelines to ensure durability and structural integrity to withstand high winds and weather events.
Next, we will walk you through the main components that make up racking equipment so you can better understand the structure that will support your solar panels.
What are the most important components of a racking system?
Solar panel racking equipment is built with 3 main components:
Each tool plays a key role in how the structure supports your panels, to ensure you get the most amount of solar power out of them.
The roof attachments are the fasteners that will be drilled into your roof in order to secure the racking system in place.
The holes these drills create will be surrounded by ‘flashing’, which is a plastic or metal shield that is inserted between shingles to prevent water from getting into the hole. However, roof attachments differ for each roof type.
To dig a little deeper, take a look at more information on installing solar panels on clay tile roofs, metal roofs, and flat surface roofs.

The module clamps attach the drilled-in roof attachments to the mounting rails. There are a few different module clamp types for each angle and corner of the solar panel.

After drilling into the roof, the roof attachments are then connected to mounting rails via module clamps that will then support the solar panels.
Although there are railless racking options available, rails are most commonly used because they can be secured to most roof angles, and because many installers are trained using rail mounting systems.

While many manufacturers produce solar panel mounts, only a handful of companies come out on top when it comes to quality. You can’t really go wrong with IronRidge, Quick Mount and Unirac, but we will walk you through the pros and cons of each brand.

Flexible Mounting Structure
In recent years, with the development of the photovoltaic industry, land and roof resources have gradually decreased. Limited by the traditional support form, the undulating mountains, fish ponds with deep water levels, and sewage treatment plants with large spans cannot be fully utilized. The emergence of flexible bracket has solved the above problems, which is a new trend in the application of photovoltaic bracket. Flexible Mounting Structure Product Highlights Reduce land occupation resources: The span is large, and the span spacing of 10~60m can be installed. Increase the use of space: the height can be customized, and the height can be set to 2.5~16m. Reduce the amount of steel: Through the use of cable structure, the cost of ordinary brackets can be effectively saved by 10~15% Saving construction costs: The reduction in the number of pile foundations and the sliding characteristics of the cable structure can reduce the construction cost and period by 10-20%. All-weather unobstructed: Overcome the ups and downs of the mountains and increase the power generation by about 10%.

Roof Rack Kit
IronRidge Roof Mounts Rack Kit provides a number of options for solar panel mounting solutions. The first is an adjustable L-foot component. Made of extruded aluminum, these L-feet are strong enough for both residential and commercial solar panel installations. The vertical slots make it easy to level the racking for your solar panel array when there are irregularities in the roof. When increased airflow or roof flashing is required, IronRidge offers two different types of roof mount standoffs. Lightweight aluminum standoffs are available for flush mount solar PV module applications, Heavy-duty, welded steel roof mount standoffs are available for tilt mount solar mounting applications.
These standoffs support common flashing products such as those from Oatey. In addition, the IronRidge standoffs are available in multiple heights. Tilt leg attachments are available for solar panel projects where installers or homeowner do-it-yourselfers wish to optimize power by tilting solar modules more directly at the sun. These extruded aluminum legs attach quickly and directly to XR100 PV rails. The well thought-out and simple design enables adjustability in all three dimensions. The IronRidge tilt legs come in a variety of lengths to cover a wide range of desired tilt angles.
IronRidge clamps provide a universal method for securing most popular solar PV modules in solar racking systems. XR100 PV rails have slots for top mounting. End clamps and mid clamps are manufactured from either 5052-H32 aluminum or extruded aluminum, depending on the clamp size. The mid clamps are uniquely designed to minimize spacing between IronRidge solar roof mount and to help maximize power density. When you choose IronRidge Roof Mounts Rack Kit you can be assured you have purchased the strongest, most aesthetically pleasing racking system on the market today.
