Best DIY Solar Panel Mounting Frames: How to Mount Solar Panels for Less

You’ve finally decided to go solar and reap the benefits of free energy from the sun. But after investing in high-quality solar panels, the last thing you want is an expensive racking system to mount them. Don’t worry, you’ve got this. With some basic materials and DIY skills, you can build your own solar panel mounting frame for a fraction of the cost.

In this guide, we’ll show you the best DIY solar panel mounts so you can get your new panels set up in no time. Whether you want a simple ground mount, roof mount or pole mount, these DIY solar panel racking ideas have you covered. Building it yourself means you can customize the design to perfectly suit your needs. You’ll be harnessing the power of the sun before you know it. The satisfaction of creating your own solar panel racking system will make those first lower energy bills even sweeter. Let’s get started!

Choosing the Right Materials for Your DIY Solar Panel Mounting Frame

When building your own DIY solar panel mounting frame, the materials you choose are key to creating a sturdy, long-lasting structure.

For the posts that will anchor your solar panels, galvanized steel is a great option. Galvanized steel posts are corrosion resistant and strong, but lightweight enough to be manageable. You’ll want posts at least 2 to 3 inches in diameter for most residential solar panel installations. Bury about one-third of the posts in concrete for stability.

For the rails that connect the posts and support your solar panels, aluminum is an ideal material. Aluminum rails are affordable, durable, and easy to cut and join together. Look for square or rectangular tubing that is at least 2 inches wide and 1/4 inch thick.

To join the rails to the posts, galvanized steel brackets or clamps are a simple solution. Or, for a sleeker look, you can weld the rails directly to the posts. Just be sure to grind down any sharp edges.

With the right materials and a little elbow grease, you’ll have a custom solar panel mounting frame in place in no time. And by building it yourself, you’ll save hundreds – if not thousands – of dollars over a pre-made kit. Your wallet and the planet will thank you.

Step-by-Step Guide to Building Your Own Solar Panel Mounting Frame

Building your own solar panel mounting frame is easier than you might think. With some basic materials and tools, you can construct a sturdy frame to securely mount your panels in a few simple steps.

Gather the necessary supplies

You’ll need aluminum rails, brackets, bolts, and screws. For a small system, 1-inch square tubing works well for the rails. For larger systems, use heavier 2-inch tubing. Buy brackets to connect the rails, and bolts and screws to fasten it all together.

Assemble the rails into a frame

Connect the aluminum rails into a rectangular frame that matches the dimensions of your solar panels. The longer rails should run along the sides, with the shorter rails at the top and bottom. Secure the joints together with brackets and bolts.

Attach the frame to strong mounts

Mount the frame to sturdy posts embedded in concrete for the most secure installation. You can also mount directly to your roof if it can support the weight. Attach the frame with pole mounts or roof mounts and lag screws.

Add panels and wiring

With the frame in place, you can now attach your solar panels. Place them inside the frame and secure them to the rails with bolts and washers. Run wiring from the panels to your inverter and you’ll be harnessing energy from the sun in no time!

Building your own solar panel frame requires some work but will save you money while allowing for a customized setup. Follow these steps and you’ll have a DIY solar panel mounting system to be proud of.

Top Tips for Mounting Your Solar Panels on a DIY Frame

When mounting your DIY solar panel frame, keep these tips in mind:

Choose the Right Angle

The angle of your solar panels is important for maximizing sunlight exposure. For the best year-round performance, install panels at an angle equal to your latitude minus 15 degrees. If that’s too complicated, a 30 to 45 degree angle will work well for most areas.

Face the Right Direction

solar panels should face due south for maximum sun exposure (in the Northern Hemisphere). If that’s not possible, aim for southeast or southwest. West-facing panels will still generate plenty of power, though slightly less than south-facing. North-facing panels are not recommended.

Leave Space for Airflow

For the most efficient solar panels, allow at least 6 to 12 inches of space behind and under the panels. This airflow helps keep panels cooler, which increases their productivity. Mounting panels flush against a roof surface impedes airflow and can reduce energy output by up to 25% during the hottest summer months.

Use Adjustable Mounts

Choose mounting racks or frames that allow for adjustment of both the angle and direction of your solar panels. The sun’s position in the sky changes with the seasons, so adjustable mounts let you re-angle panels for optimal exposure during any time of the year. This flexibility will ensure you get the most power from your system year-round.

Consider Your Roof’s Condition

If installing panels on your roof, make sure your roof is in good condition first. As a general rule, solar panels can last over 25 years, so you want to ensure your roof will last at least that long as well. If you need to replace the roof soon, do that first before investing in solar panels. The panels and mounts must be properly attached to a stable, long-lasting roof surface.


So there you have it, a few of the best DIY solar panel mounting options to get your system up and running for less. Any of these designs can work great, you just need to consider your specific needs, skills, and budget. With some time and patience, you’ll have your solar panels mounted and harnessing the sun’s energy in no time. And you’ll feel good knowing you did it yourself and saved a bundle. Now get out there, pick a design, buy the parts, and start building your DIY solar panel mount. The sun is shining and the savings are waiting! You’ve got this.
