What should I look for when it comes to racking?

There are a few major racking brands you should be aware of in the solar industry:
SnapNrack
Unirac
Ironridge
Sunlock

Cost -  According to the National Renewable Energy Laboratory (NREL), solar racking should cost approximately $0.10 per Watt (W)

Racking will have the following components:
1. Flashings - Installing solar panels on a roof involves drilling holes that are susceptible to leaking if not properly covered. In order to prevent water damage to your property, solar installers use flashing as part of their solar mounting solution
2. Mounts - Solar panel systems are attached to your roof with mounts. Mounts are usually attached to your roof with a bolt through the flashing and into a rafter, securing your whole system. Your rafters should be structurally intact and appropriately spaced to accommodate the mounts for your solar panel system.
3. Rails - Mounts hold up rails, which are the component of solar racking that your solar panels sit directly on top of.  
4. Clamps - keep solar panels secured in place on racking, installers use clamps, which link solar modules to the rails below
A good mounting system should be easy to install, made from quality, rust-free materials and should protect a system’s cables.
