Unirac manufactures high-quality racking equipment for both residential and commercial solar energy systems. Their racking is known for being well constructed and suitable for a number of site conditions, including challenging locations where snow or wind loads may be high. Engineering documentation is easily available through their website, which ensures speedy permit approval. While their web-based design tool makes it easy to generate a bill of materials for both DIY and professional installers. From construction to installation, Unirac may offer the racking solution you have been seeking for your next solar installation.

Unirac's SolarMount rails are the structural foundation for both of their residential and commercial racking equipment. The rails are available in light, standard and heavy construction, which rail you will need is dependent on the mounting application as well as the site conditions. Light rails are cost effective and work well for small and medium sized solar systems, where site conditions are light, meaning, below average wind speeds, snow load, etc. Standard rails are used in the majority of residential roof mount installations, like Light rails, they are affordable, but stronger and able to handle a higher load than the light rails. Heavy rails are most commonly used for ground mount installations, which typically call for a higher grade rail to meet county requirements. Heavy rails may also be used for roof mount installations when necessary.

DIY and professional installers can take advantage of Unirac's design platform, Ubuilder, to generate an accurate layout and bill of materials. The tool also provides clear indicators of module placement and allows for more versatile design completion than competing design platforms. The Ubuilder's learning curve ranges between beginner to intermediate depending on which tool is being used.

Unirac Roof Mount Solutions

Unirac is compatible with shingle, tile, flat and metal roofs through the utilization of their wide range of attachment point solutions in combination with their SolarMount rails. There are minor differences in cost across the various attachment points, however installation is largely the same and often require single tool installation across the various attachment point options. Unirac's kits provide complete attachment solutions no matter the roof type, diminishing the need for supplemental racking equipment like L-feet, wiring, lag bolts or attachment hardware.

For flat roof mount solar systems, Unirac offers the RMDT, RM5 and RM10 series ballast bays .The RMDT series is an 8° dual tilt ballast solution that eliminates the need for wind deflectors and fire skirts, allowing for up to 33% more modules to be installed for commercial projects. The RM5 and RM10 series are more ideal for residential solutions, the mounts are designed at 5° and 10° angles. All Unirac’s ballast bays use optional perimeter and column spacers and allow for multiple block configurations which allows for more flexibility in design.

In addition to the above roof mount applications, Unirac’s SFM Infinity is a rail-less racking system that is compatible with composite shingle, and tile roofs. The rail-less design allows for a lower bill of materials (up to 40%) which saves on your initial investment and saves time during installation. Solar panels can be easily configured in mixed panel orientations to maximize space and increase energy production.

Unirac Ground Mount Options

Unirac offers two ground mount racking solutions: Ground Fixed Tilt (GFT) and the Unirac Large Array (ULA) series . As the name implies, the ULA series is ideal for large projects, most commonly large scale commercial and utility installations. The GFT series works for both lightweight and standard solar system demands and work across a wide range of environmental conditions. The system comes with 20° and 30° tilt options for systems between 2kW to multi-MW.

Unirac’s ground mounting solutions are pre-engineered on a regional basis, ensuring a smooth permitting process and quick approval with city planning offices and utility providers . Knitted hardware with integrated bonding and pre-assembled parts fast track the installation and provide stable, grounded structural support for your solar array.

Designing a Unirac Solar Racking System

Unirac provides DIY homeowners and installers with a quick, easy and accurate tool to size out their solar energy racking system with Ubuilder. Ubuilder can be used to design both roof mount and ground mount systems and allows for custom configurations.

The tool allows you to design your project off of an aerial view of your roof or by entering the system configuration manually. Mapping a rooftop for solar with the draw shape tool can be difficult to get the hang of, however, it is very useful for complex projects with multiple roof faces. In addition, installers can import project details from Helioscope, a feature only compatible with Unirac's design tool.

Unirac's Ubuilder provides an accurate bill of materials, project details, engineering information and more, making racking design and system approval simple for installers and DIY homeowners alike. Of the available racking software solutions, the Ubuilder is the most useful for multi-faced roof mount systems, the draw tool allows the user to map multiple roof faces while the solar addition provides clear representations as to the quality of the placement of the modules. Other design tools are limited by their dimension based design technology in this regard.

Unirac Pricing and Warranty

Unirac's roof mount racking equipment is suitable for residential, commercial and utility scale solar energy installations.
