Solar array ground mounts, designed to support solar panels at ground level, are increasingly common in residential and commercial settings. However, these solar arrays, which consist of metal frames or structures, must be securely anchored to the ground for stability, safety, optimal performance, longevity, compliance, theft protection, and insurance requirements.
Ground mounting ensures that solar panels remain stable and secure in adverse weather conditions such as high winds, heavy rain, or snow. Proper anchoring prevents the panels from tipping over or shifting, which could result in damage to the panels and surrounding property. Securing the structure also assures that the panels remain in the optimal position for solar exposure, maximizing energy production. Grounding and securing the solar array may also be required for regulatory compliance, and to minimize the risk of fines or liability.
Instead of more costly, complex ground mounts that involve the use of concrete footings or foundations, an increasingly popular and economic solution to this issue is earth anchors. These heavy-duty aluminum anchors are driven or screwed into the ground and attached to structures using cables, straps, or brackets. The anchors can be easily installed into sand, soil, and hardpan at a fraction of the cost, time, and labor of concrete footings.
One technology that has been used to ensure the safety and stability of solar arrays is that of Penetrators from Rhode Island-based American Earth Anchors (AEA). These are screw anchors made of heat-treated 356 aluminum that can be installed with a portable impact wrench or machine PTO drive fitted with a suitable tool.
Reliable, Cost-Effective Ground Mounting:
• For solar ground mounting, the screw anchors, available in lengths from 14” to 46”, can provide 2,500 to 14,000 lbs. of holding power in asphalt or hard pan soil, with rack rates for wind up to 145 mph.
• The 36” and 46” Penetrator earth anchors are an effective alternative to utilizing concrete footings for solar array ground mounting at essentially half the cost.
• Unlike the use of concrete footings, the earth anchors do not require any digging, forms, pouring, or waiting to cure. No concrete truck access is necessary.
• The earth anchors are easy to level by simply screwing the units down or up as needed.
• The earth anchors are strong, durable, and lightweight so can be shipped economically, easily handled onsite, and resist corrosion. A wide variety of brackets and bases expands securing options and can be customized as needed.
