Solar Panel Racking System

Ground Screws

• Provide a better alternative for Ground Mount Solar Array’s
• Have no concrete bases, reducing the amount of Impervious Surfaces
• Eliminate the need for digging and soil removal
• Reduce installation times significantly compared to other Ground Mounting Methods

Understanding Impervious Surfaces

Impervious Surfaces are Ground Materials that are not able to absorb water.

There are numerous state laws and regulation that prohibit "Impervious Surfaces" from covering large expanses of property.

These surfaces include anything such as roadways, homes or any other cover that does not absorb water.

This prevents aquifers from being replenished and can cause soil erosion,run-­‐off, flooding and other environmental hazards.

Preventing Impervious Surfaces

As shown in the photograph, the Solar Panels are mounted on a racking system that elevates them above the ground surface. The racking is supported on the ground screw with a tie down bolt.

This eliminates the need for any concrete pads used in other conventional racking tie down systems. Solar Panels by themselves are impervious, but water will run off the panels and between them down to the ground where it will be absorbed, replenishing aquifers.

Law S-921

Law S-921 specifically exempts solar panel installations from being considered impervious surface cover. As stated, "Solar Panel" means a panel or plate, or a canopy or array thereof, that collects or captures solar energy or radiation to provide energy or power, and includes nocturnal heat radiation, flat plate or focusing solar collectors, or photovoltaic solar cells and excludes the base or foundation of the panel, plate, canopy, or array.

This bill amends (1) P.L.2004, c120, "Highlands Water Protection and Planning Act"; (2) P.L.1968, c285, relating to county site plan reviews.

This bill supplements the "Municipal Land Use Law," (3) P.L.1975, c291, to exclude solar panels from being designated or deemed, or calculated, as impervious surface or impervious cover.



Law S-921 exempts solar panels from being considered "impervious cover" because they are elevated panels that do not completely cap the ground and prevent water absorption.
