Ballast Method
RequiredThis is how you will hold down your panels and frames. IntegraRack offers a few options, from weight on the frames with the EarthBallast method to screwing the frames in place using the EarthScrews or Lag Bolts.
- EarthBallast is a great option for any location, as it only requires gravel or water tanks as the weight to hold the frames and panels down
- AnchorSpikes are great for dense, compact soil; the spikes are hollow and allow the epoxy to seep into the ground, securing the frames
- Footing Lag Bolts are used with frames mounted on concrete slabs
- EarthScrews are similar to AnchorSpikes, but instead of using epoxy to secure the frames down, the screws dig into the earth to hold the frames in place; dense soil required

Integrarack IR EarthScrew Mounting Kit 10 Pack, 30-Inch Screws for BallastRack Frames, Solar Mounting Method for Dense Compacted Soil
The IntegraRack IR EarthScrew Mounting Kit secures IntegraRack BallastRack frames into dense, compacted soil as a ground mount solar panel anchoring system. Each kit includes 10 high-strength screws measuring 30in. This is enough to mount five BallastRack solar racking frames or one row of four solar panels. The EarthScrews install without heavy equipment and allow for post-installation leveling, making them a practical anchoring option for residential, off-grid, or small commercial ground mount solar installations.
Specifications:
- 10x 30″ EarthScrew ground anchors
- 1x 13mm ratchet wrench for BallastRack frame assembly
- Material: high-strength steel
- Finish: black zinc
- Mounts five BallastRack frames
- Compatible with all IntegraRack BallastRack models (IR-15, IR-30, IR-45 series, IR-40FSA series)
- Weight: 10lbs
- Box dimensions: 30×8×8in
Note: IntegraRack recommends professional installation. You must test one EarthScrew at the installation site to confirm a minimum of 1,000lbs of uplift resistance before proceeding with the full installation. The IR EarthScrew works only in dense, compacted soil. Do not use it in sandy, silty, or rocky terrain.

About the IntegraRack BallastRack Ground Mount Kit
The IntegraRack BallastRack kit is a build-to-site ground mount. You choose the frame that sets your tilt angle, then choose the anchoring method that matches your soil and wind conditions. Every frame is rail-free and clamps directly to the module, so a full array goes together with hand tools and no rail runs to cut or align. Frames assemble in about two minutes each, and most installations need no concrete footings, post pounding, or earth augers.
How to Size and Configure the Kit
Plan on one frame per solar module, plus one extra frame at the start of each row. The frames set their own spacing: position the base tubes one inch less than the width of your module, and the IR-F2 flange clamps hold the module along its edges. Because each module can slide up or down on the clamps, you can fine-tune ground clearance and set a height that sheds snow. Add the anchoring kit that fits your site, and the same frame works with any of the four methods.
Frame Angle Options
The kit covers four tilt configurations. The IR-15 is a fixed 15 degree frame with a 0 degree hurricane setting, suited to high-wind and low-latitude sites like the Gulf Coast. The IR-30 is a fixed 30 degree frame for general year-round production across much of the country. The IR-40FSA sets any angle from 15 to 40 degrees and adds extra ground clearance, so you can dial in the tilt for your latitude one time at install. The IR-45ASA adjusts from 15 to 45 degrees per panel, which lets the same array run steep for a low winter sun and shallow for a high summer sun. Aluminum frames use USA-sourced 6061-T6, and a black-zinc-plated high-strength steel option is available on some models for added corrosion resistance.
Anchoring Methods for Any Soil
Four anchoring methods cover common site conditions. EarthBallast works almost anywhere: a geotextile sheet is epoxied across the frame base tubes, then loaded with gravel, road base, or water tanks to hold the array by weight. AnchorSpike suits dense soil, using hollow barbed spikes that let epoxy flow into the ground for holding power. EarthScrew is for dense, compacted soil, driving 30-inch screws that also allow leveling after install. Footing Lag Bolt fastens the frames to a concrete slab or patio for the highest wind resistance. The anchored methods, AnchorSpike and EarthScrew in particular, call for a site uplift test before full installation, and IntegraRack recommends professional installation for those. EarthScrew and AnchorSpike are not for sandy, silty, or rocky ground.
Rail-Free Design and Module Fit
There are no rails to buy, cut, or ground. The IR-F2 flange clamps bond the module frame directly to the racking, which cuts part count and speeds assembly. The system fits virtually any full-size framed module, including large commercial panels, and each module sets its own frame spacing, so you do not need to match a specific panel model. Aircraft-grade aluminum keeps each frame light and compact enough to ship by ground parcel rather than freight.
Engineering, Certification, and Warranty
IntegraRack racking conforms to UL 2703 for mechanical strength and electrical bonding when installed as instructed. The frames are wind-tunnel tested and carry stamped, model-specific engineering, and they are tested for use in all 50 states by Phoenix National Laboratories. Snow load ratings reach 100 psf, and wind ratings depend on the frame, tilt angle, module size, and anchoring method, so check the stamped datasheet for the frame you choose. A building permit is not required for most ground mount installations, and IntegraRack publishes documentation you can bring to your local authority. Every frame is backed by a 25-year limited warranty covering manufacturer defects.
Frequently Asked Questions
One frame per module, plus one extra frame at the start of each row. Set the base tubes one inch narrower than your module width to establish spacing.
Only if you choose the Footing Lag Bolt method, which bolts to a slab or patio. EarthBallast, AnchorSpike, and EarthScrew all install without concrete footings.
EarthBallast works on almost any ground and holds the array with gravel or water weight. AnchorSpike and EarthScrew are for dense or compacted soil and require a site uplift test first. Footing Lag Bolt is for existing concrete. None of the anchored methods are rated for sandy, silty, or rocky ground.
The IR-F2 clamps fit virtually any full-size framed module, including large commercial panels. Each module sets its own frame spacing, so there is no panel-specific hardware to match.
Most ground mount installations do not require one, and IntegraRack provides documentation for your local authority. Confirm with your jurisdiction before you install.
The frames assemble in about two minutes each with hand tools. For the AnchorSpike and EarthScrew methods, IntegraRack recommends professional installation and requires a site uplift test to confirm holding capacity.
