Should you go with a rail or rail-less PV mounting system on your next installation? Depending on who you ask, you will get strong opinions for both. I liken the choice to dieting. Don’t eat meat! Actually, don’t eat carbs! No, it’s sugar that’s the killer! Milk is bad! You need milk!

The commonality here, at least to me, is everyone is right, and no one is right. What works for one person or project may not work for another, and maybe the answer is a little bit of all of the above. The real key is knowing what you need, what you prefer and the attributes of your available choices.

All systems have their pluses and minuses, and depending on the job at hand or your business plan, either could be the right solution for you and your customers. So, when, where and why would you go in one direction or another?

Reasons for Rails

For starters, it is easier to start. Rails involve a lower learning curve. You can get a crew trained on system installation fairly quick, and part of the reason for this is a more forgiving layout. SunModo, which offers all types of systems, says that on a straight-forward roof, your layout time is reduced.

“Our railed systems are flexible to accommodate complicated roof conditions and crooked roofs,” says Stella Sun, marketing director for SunModo. Its EZ Roof Mount can accommodate both rafter and decking applications.

The most ideal applications, according to Jason Xie, president at Magerack, is a large, simple array layout or a crooked roof. “A roof with a lot of obstacles — vents, stack, etc. — can present issues,” Xie says.

Look for low to moderately pitched roof applications in the 8 to 44 degrees range. Railed systems will require more engineering on steep slope pitched roof applications, 45 degrees or greater, according to SunModo.

“All rackless systems don’t use rails. That’s a time savings, but if the number of attachments is higher, if the parts costs are higher, or if there are still fiddly little parts that need adjustment, the overall costs are higher — not lower,” says Barry Cinnamon, founder of Spice Solar. “Installers should carefully account for all parts, including roof attachments.”

Some of the benefits aren’t inherent in the general rail system, but have been built in to select products. PV Racking, for example, has eliminated the need for clamps on the roof, which increases the speed of installation and save 20 to 30 percent in labor time. Its elongated L-Foot allows for faster and easier rail alignment too.

Reasons to Share

Shared rail solutions use rail to hold the modules in place, but reduce components elsewhere, such as mid and end clamps. As Shane Shamoo, president of Solar Speedrack, explains it, shared rail systems cover the entire side of the module, and the module frame becomes “bonded” to the rails and reduces the strain on the module.

“Because the rails are shared, a two-up installation would require only three rails as compared to four for a standard mid and end clamp system,” he says. This provides its own unique nimbleness for either landscape or portrait installations on all roof types. Shared rail also requires fewer roof penetrations, lessening the potential of a “floating” penetration.

SunModo says shared rail is great when modules are in landscape and the rail has to be run E-W and you cannot clamp to the short sides of the module, or when the rail has to be run N-S and the module must be in portrait. Less than ideal shared rail applications would be those with sagging trusses, uneven shingles, uneven roof framing or any other situation that would cause difficulty creating perfectly level rows of rail.

“Since we offer a shared rail system that does not require clamps, the first rail automatically aligns the first row of panels, which eliminates the need to straighten panels and speeds up the installation,” says Devin Paris of PV Racking’s shared rail system. Some systems come with rail spacers to allow for fast and easy spacing between the rails, eliminating the need to pull a measurement between each rail.

Reasons for Rail-less

As you might expect, the benefits of a rail-less solution come from not having rails. I know, I really blew the cover off that one, but it’s worth understanding those benefits: Rail-less products are compact, easy to handle and cheaper to ship.

“A rail-less system provides the suppliers the opportunity to cut manufacturing and shipping costs, and the installers are limiting time on the roof with fewer components to handle and install,” SunModo noted.
Milton Nogueira, business development manager with Roof Tech, notes that it is easier to handle any increments of PV modules, which also opens up more possibilities such as any pitched roof top with asphalt roofing, roofs with less space or roofs with lots of obstacles.

Rail-less mounting can be much quicker, but installers must know what they are doing as there can be a steeper learning curve.

Rail-less is also good for mounting in landscape, but less ideal for portrait orientation, says SunModo. Xie recommends avoiding rail-less on crooked roofs, higher wind areas and tile roofs. Nogueira says he would avoid discrepant roof surfaces with variations over 1 in. You’ll always want to consider the extra attachment points you are adding — the more attachment points, the lower the point load and the less impact on the attachment due to thermal contraction and expansion.

Clamps of Approval: Here’s what to look for when selecting PV clamps


Photo courtesy of AceClamp

The following advice was sent our way via Civic Solar. Check them out here.

Clamps, the racking component used to fasten and ground modules to rails, are an integral component of a racking system. Knowing what to look for in a clamp is a great place to start when vetting racking solutions. Ideally, solar module clamps should be versatile, high quality, aesthetically pleasing and ultimately save you time on the roof.

Versatile solar module clamps are important because they allow for streamlined purchasing and ensure that you always have the right materials in stock. With framed modules ranging from 30 to 50 mm in height, a clamp that can accommodate any height means that you only have to worry about stocking one part, regardless of the modules that you install. With module prices dropping, this simplicity allows you to opportunistically shift your module purchasing without having to worry about changing the racking you stock. Going one step further, the most versatile clamps will be both module height agnostic and double as a mid and end clamp. Having both of these features reduces SKU count and increases simplicity.

Does it meet standards?

Quality of the clamp needs to be considered because racking systems are responsible for the structural integrity of solar systems that will be around for more than 20 years. Some factors to consider are code compliance and certifications, the amount and quality of testing that has been done and the warranty provided by the manufacturer.

A clamp needs to be UL 2703 Listed, which means it passes electrical, mechanical and fire testing. Be sure the clamp is UL Listed rather than just UL Classified or UL Recognized. UL Classified means it has only passed a portion of the required testing, and UL Recognized means that only a component of the racking system has passed a portion of the testing.

Warranty is important because it shows the level of confidence a manufacturer has in its product. The industry standard for a racking product warranty is 20 years.

Is it a looker?

Aesthetics of a clamp should be considered because sleek looking systems will increase the adoption of residential solar.

For a clamp, more attractive means having multiple finish options and a hidden end clamp. Matching the color of the clamp to the color of the module frame will give the system a cleaner look. A hidden end clamp eliminates protruding rails, helping rail-based systems rival the aesthetics of rail-less while remaining more cost effective.

Does it save you time?

Purchasing a clamp that is pre-assembled with a low part count and integrated grounding can save you tons of time. Now, almost all of the top racking brands have integrating grounding, where modules are bonded directly to the rail through teeth on the clamps that bite into the module’s anodized coating. This eliminates components, reduces cost and results in significant labor savings. Also, choosing a clamp that is able to stand alone in the rail channel will increase ease-of-install and turn a two person job into a one person job. Some brands accomplish this through single pre-assembled pieces that have a robust enough end to stand alone while others use spring loaded clamps. Another consideration is whether the mid clamp has a t-bolt or square bolt end. Square bolts need to be run through the rail prior to installation, whereas t-bolts can be inserted into the rail at any point.

Looking for these key features will ultimately save you time and money and allow for a smoother installation process.

  • Certifications: UL and ASTM tested for use with extensive list of metal roofing manufacturers, profiles, materials and gauges.
  • Warranty: 25-year defect warranty (applies only when the S-5! product is properly installed, used and maintained).


AceClamp’s family of clamps

AceClamps are factory-assembled clamps with patented design features that allow strong connections to standing-seam roof panels without the use of set screws or any other loose parts that could damage the surface of the roof panel. Accessories include Solar Kits for securing PV solar panels; a Micro L-Foot to mount microinverters directly to the standing seam roof rib; and a custom designed L-Foot for attaching a racking system to the AceClamp when needed. AceClamp designs have been vibration tested during the development stage and incorporate special locking features to ensure that the bolts do not back out when subjected to vibratory loads from wind flutter and light seismic activity.

How does it save time and cost?

AceClamps and Solar-Kits are pre-assembled at the factory saving time at the jobsite. Four clamp styles fit the majority of the roof panels on the market, resulting in inventory cost savings. AceClamps install in less than half the time as most set-screw mounted clamps

  • Material: 6061-T6 aluminum and 303 stainless steel
  • Certifications: AceClamp ML and A2 UL Listed to 2703; AceClamp ML approved by Factory Mutual (4471) for wind uplift attachment. A2 and Solar-Kit tested to UL 467 Grounding.
  • Warranty: 20-year limited
