Where is unirac manufactured?

Unirac designs and tests its products in Albuquerque, New Mexico, and manufactures them in United States and Ontario, Canada. Unirac solutions meet “Buy American’, ARRA and Ontario Power Authority FIT (Feed-in Tariff) and microFIT criteria. More than 90 percent of the company’s supply chain is US-based.

What is racking in solar?

Also called photovoltaic mounting systems, a solar racking system is used to safely fix solar panels to various surfaces such as roofs, building facades, or the ground. The system is designed to easily be retrofitted to existing rooftops and structures.

What is ballast mounting?

A ballasted mount offers all the benefits of solar panels without the impact to your roof. That’s because solar ballasts aren’t attached to roof rafters the way most solar panel installations are. Instead, they sit directly on top, cemented to the surface with concrete blocks.

What is fixed tilt?

Fixed-tilt PV systems use two separate angles that determine their orientation relative to the sun: the azimuth and the tilt. The azimuth specifies the compass direction that a tilted panel is facing: north, south, east, or west. Most panels in the Northern Hemisphere are south-facing.

How are solar racks installed?

Solar panel systems are actually attached to your roof with mounts. Mounts are sometimes referred to as “feet” and are usually attached to your roof with a bolt through the flashing and into a rafter, securing your whole system. There are many varieties of mounts used in different racking systems.

What is ballast structure?

Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship.

What are ballast blocks?

Take the humble ballast block—this seemingly simple piece of concrete that holds down a flat roof mounting system can lead to a lot of questions about weights, dimensions, and materials. Since finding and placing the blocks is the installer’s responsibility, it’s a common and sometimes last-minute concern.

What latitude is best for solar panels?

between 30 degrees and 45 degrees
Most solar arrays are installed at an angle that best optimizes sunlight exposure for that location. For the vast majority of U.S. property owners, the ideal angle for a solar panel installation is close or equal to the latitude of your home (on a south-facing roof), somewhere between 30 degrees and 45 degrees.

How much more efficient are tracking solar panels?

The biggest benefit of a solar tracking system is that it offers a boost in electricity production. Generally, a solar panel system with a single-axis solar tracker installed sees a performance gain of 25 to 35 percent. A dual-axis tracker bumps performance up by another five to 10 percent.
