Krinner Ground Screw Stage

Engineered Ground Screws for Solar, Carports, and Agri-PV

Krinner ground screws are a trusted global foundation solution, offering fast, concrete-free installation with excellent load-bearing capabilities. These galvanized steel screws are inserted directly into the ground using a rotational method, making them ideal for projects on uneven terrain, sloped sites, or tight construction zones. Their high strength and modular extendibility make them suitable for both shallow and deep foundation requirements.

Originally developed to support large-scale solar infrastructure, Krinner ground screws have proven their value across solar farms, carports, and agri-PV applications. The V-series and S-series lines support a wide range of installation scenarios, while optional extension elements allow installers to adapt on the fly. Each unit is hot-dip galvanized for durability and designed to meet international standards for long-term performance in tensile and compressive load transfer.

All-Terrain Compatibility

Performs reliably in sloped, rocky, or hard-to-access areas where traditional foundations are costly or impractical.

Equipment-Driven Installation

Installs in minutes using powered ground screw drivers—no digging, concrete, or curing time required.

Modular and Extendable

Plug-in extensions adapt to site depth requirements and eliminate the need for pre-poured foundations.

Environmentally Friendly

Minimizes soil disruption and allows for simple removal or relocation with zero excavation or waste.

Optimized Ground Mounting with Krinner Screws & IronRidge

IronRidge Ground Mount + Krinner Ground Screws

Solar Electric Supply offers fully engineered IronRidge ground mount systems that are fully compatible with Krinner Ground Screws. These integrated solutions combine the structural strength of IronRidge racking with the proven foundation technology of Krinner, delivering fast, code-compliant installations for residential and commercial projects.

The result is a streamlined solar mounting system capable of withstanding extreme weather, with no need for trenching or concrete. Perfect for hard-to-access terrain, these systems offer speed, versatility, and long-term performance without disturbing the environment.

Why Use Ground Screws?

Ground screws provide a fast, eco-friendly foundation solution without digging or concrete. Ideal for uneven or sloped terrain, they simplify installation and minimize site disruption—making them a top choice for both rural and urban projects.

IronRidge System Integration

IronRidge Ground Mount Systems are certified for use with Krinner and American Ground Screw. Compatible with 2" and 3" Schedule 40 pipe, and secured using IronRidge’s custom Set Screws—no welding, concrete, or trenching required.

Removability & Reusability

Unlike poured concrete foundations, ground screws can be fully removed and reused without damaging the site. This makes them ideal for temporary installations, relocatable arrays, or projects on leased land.

Installation Best Practices

Ground screws are machine-driven into position, then connected to the substructure via downtube and set screws. For best results, select screws without a top flange and follow torque requirements outlined in IronRidge’s installation guide.
