We look at the pros and cons of rail and rail-less PV mounting systems

Quick Mount PV’s E-Mount Lag

Photo: Quick Mount PV’s E-Mount Lag

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.

This new product started shipping in May and is a larger version of the previously released Rapid Shutdown Box-Single. These boxes eliminate the need for external power supplies, any additional ground-level hardware and any extra conduit since it is directly connected to the inverter through the same DC conduit as the DC homeruns. The rapid shutdown function is initiated whenever AC is not present. Once triggered, the DC lines are rapidly discharged by the Fronius SnapINverter.

2016 Solar Mounting/Racking Guide: Product Showcase

PV mounting solutions

Photo credit: EcoFasten Solar

Most of you may have learned that the earth is not flat. Which is too bad, really. If it was flat, we’d just place PV panels all over it and call it a day. Our Mounting Guide would certainly be a lot less interesting.

But no, of course it isn’t flat. It’s not even round, really. It’s hilly and bumpy and slanted and hard and soft. It’s also full of wind and falling water and ice. And sometimes, when the gods are bored, the ground literally quakes. And that’s just on one site.

Somehow, on top of all that, we are now installing GWs of renewable energy. How is it even possible? Why, mounting and racking solutions, certainly help. Below is a guide to many of today’s top mounting/racking companies, the services they offer and a standout product in their lineup. And if you missed any of our other Mounting Guide articles this year, check those out too:
