Complete kits, not just rails
Ground-mount kits here include the foundation hardware, whether driven piles, helical piers or poured footings, that a crew actually needs on site, not just the racking rail system.
Industries
Ground Mounts
Ground-mount racking kits for residential jobs without a usable roof, sourced with the foundation hardware a crew needs on-site.

Ground-mount kits and foundation hardware
Foundation matched to soil conditions
Foundation type gets selected against regional soil and frost-depth conditions instead of a single default that may not hold in every geography.
The rapid-shutdown advantage
Ground-mount arrays fall outside NEC 690.12's rapid-shutdown requirement for conductors on buildings, which simplifies the BOS list compared to a rooftop job on the same property.
Fewer sourcing trips, simpler BOS
Show up with the full kit
Foundation hardware ships with the racking instead of a separate sourcing trip once the rails are already on site.
Skip unnecessary rapid-shutdown components
The ground-mount exemption gets applied correctly, simplifying the BOS list without missing a requirement that does apply.
FAQs
When does a residential job call for ground-mount instead of rooftop racking?
Ground-mount makes sense when the roof cannot carry the system, whether from age, structural limits, shading, an unfavorable orientation, or simply too little usable area. Open land adjacent to the home, larger system sizes, and homeowners planning a future roof replacement also push jobs toward ground-mount. Sunhub supplies complete ground-mount kits so a crew arrives with rails and foundation hardware together.
What foundation options exist for residential ground-mount racking?
Common residential foundations include driven steel piles, ground screws, and concrete piers or ballasted footings, with the right choice driven by soil type, frost depth, and local wind and snow loads. Rocky or unstable soils may call for a geotechnical check or a helical pile. Matching the foundation to actual site conditions is what keeps the array within code and manufacturer specs.
Does ground-mount racking avoid NEC rapid shutdown requirements?
NEC rapid shutdown under 690.12 applies specifically to arrays on or in buildings, so a true standalone ground-mount that is not attached to a structure generally falls outside that requirement. Other NEC provisions for disconnects, grounding, and labeling still apply, and the AHJ has the final say. Confirm with your local inspector before leaving rapid-shutdown components off a design.
