Your guide to solar panel mounts in 2023


guide to solar panel mounts

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

    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 $1,000 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:

    • Roof attachments
    • Module clamps
    • Mounting rails

    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. 

    Roof attachments

    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.

    Module clamps

    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.

    Mounting rails

    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.

    Which roof mount brands are best?

    The top three, high-quality, solar mounting and racking brands are:

    • Ironridge
    • Quick Mount PV
    • Unirac 


    Originally, IronRidge supported mostly small, off-grid projects. But today, IronRidge is known for its uniquely shaped and durable XR rail series for pitched roofs. They have equally great options for flat roofs and ground mounts, as well.

    Quick Mount PV

    Quick Mount PV sells just about every solar roof mounting product available for any type of roof - from metal roofs to low-sloping shingle roofs.


    Unirac sells mounts for flat roofs and fixed-tilt ground-mount frames. Unirac’s solar mounts each come with different tilts, allowing the direction of the solar array to be independent of the angle of the roof, ensuring the best productivity.

    Each brand offers no obvious weaknesses, and each offers very innovative mounting and racking kits to meet most solar needs. 

    You can buy any option through a local solar equipment supplier for DIY projects. But if you work with a solar installer, they will buy the panel mounts for you since they know what will work best with your roof and solar panels. 

    Where to buy solar panel mounts

    Tackling a solar panel project DIY-style can make things a bit more complicated. Most of the time, you cannot go out and buy a fully-constructed solar panel mount system. You need to buy each individual part separately to then form a complete mount. If DIY is the route you want to go, buying entire solar panel kits with their corresponding racking solutions makes things easier. 

    If you are not purchasing a kit, you can browse racking equipment on the AltE website and purchase the different components that make up the racking system. Just make sure they are the proper size for the solar panels you purchase. 

    The best way to make ensure your solar installation goes off without a hitch (and uses the proper equipment suited for your specific roof) is to work with a licensed solar installer.

    Which ground-mount system is best?

    A problem with rooftop solar is that it’s heavily constrained by the characteristics of your roof. Homeowners who install ground-mounted solar panels do so for one of three reasons:

    1. They have insufficient roof space
    2. Their roof faces north - which is bad for panel output
    3. They want to optimize the performance of their system

    Solar panels produce the most energy when they’re facing south. Depending on the orientation of your house, this isn’t always an option. On a roof, there might be further limitations like shade from surrounding buildings and trees.

    Options to choose from include ground mounts that can be secured into the ground or ballasted mounts. Ballasted mounts sit on top of the ground and are not secured in - but are held down by the weight of the panels themselves. Ballasted ground mounts tend to be more popular since there is no drilling required for installation

    The best options for ground mounts also come from the top brands, Ironridge and Unirac.

    Ironridge Ground Mount Systems 

    These are built to be long-lasting, flexible, and withstand any weather. They also come with a 25-year warranty

    Pricing is difficult to pinpoint because it will depend on the size of your solar array, costs of material at the time of purchase, and the fact that many suppliers ask that you request a quote.

    Unirac Ground Fixed Tilt

    The Unirac Ground Fixed Tilt is another great choice - it is durable and lightweight and also has a 25-year warranty. Unirac ensures fast shipping times and ease of construction. You can work with a licensed solar installer to determine which ground mount system is best for your terrain and solar panels. 

    How much will a solar panel system plus racking and mounting cost?

    Including racking and mounting, an average 6kW solar system would cost about $18,000 given the US average of about $3.00 per watt as of January 2023. After applying the federal solar tax credit of 30%, that works out to $12,600.

    It is up to you and your energy needs whether or not you want to install solar tracking systems, but generally, installing either roof or ground-mounted solar panels will work for any home. 

    Working with licensed installers is the best way to determine which solar panel mount system will work best for your roof.
