Integra-Rack IR-15/30/45

My go-to rack is IntegraRack. I have tested everything available and these are the best.

Integra-Rack IR-15

For people close to the equator or tropics

Integra-Rack IR-30

For people in USA and most areas

These are currently my favorite. This is why:

Takes one hour to set up a 4-panel system (most others take 3X longer to assemble)
Cheapest option if you factor in mounting costs
Wind Load Rating of 150 MPH
Snow Load Rating of 100lbs per sq ft
Portrait Mounting for Easier Wiring

Need an Adjustable Array?

Live far from the equator and need to tilt your panels for different seasons?

IntegraRack IR-40FSA BallastRack Adjustable Angle

Adjustable Angle for Maximum Performance

Adjustable for ANY Angle and Higher Off the Ground

The IntegraRack IR-45ASA is a seasonally adjustable ground mount that lets you set each solar module to its own angle anywhere from 15° to 45°, so you can capture a low winter sun and a high summer sun from the same array.

Seasonally Adjustable for Maximum Output

IntegraRack IR-EW15 Solar Farm Rack

Rail-free 15° East/West frame supporting two large solar panels.

Solar Farm Racking

The IR-EW15 supports two large solar panels on one rail-free aluminum frame—one facing east and one facing west at a fixed 15° angle. This configuration spreads production across more of the day and allows rows to sit closer together, fitting more solar capacity into the available land.

The lightweight frame installs without concrete footings, earth augers, or driven posts. It can be secured with compatible earth screw, ground ballast, or concrete slab mounting kits depending on the site. One frame supports two panels, plus one additional frame is required to begin each row.
