Four energy dense solar mounting systems for C&I rooftops

SunModo SunBeam

sunmodo

As a permanent part of the building and roof structure, the SunBeam system eliminates any abrasions, moss build up and need of system removal for roof repair or re-roofing. In addition, it provides shading of HVAC equipment, increasing efficiency and faster temperature response. Twenty-year warranty.

Material: High-grade aluminum and 304 stainless steel hardware. Anchor-only attachment.

How it maximizes energy density: The SunBeam system elevates above obstructions such as HVAC, pipes and vents. By spanning over roof obstructions such as HVAC, pipes and vents, the system takes full advantage of the available roof surface thereby maximizing the PV system size. The system can be easily adjusted to account for the multiple roof pitches on site.

Everest Solar D Dome R²

everest

The D Dome R² system is an east/west commercial flat roof solution. The third generation of this product is now rail-less with only five major components and minimal hardware. It sits at a fixed 10-degree pitch and allows for 3.5-in. inter-row spacing. Twenty-year warranty.

Material: Aluminum, ballast with attachment optional. The ballast blocks sit under the panels.

How it maximizes energy density: Everest Solar Systems believes east/west systems are more efficient south of the tropic of cancer. First, an east/west system practically eliminates inter-row spacing which allows more modules on the roof, thus increasing module density. On one internal study, Everest compared a the production of a 10-degree south-facing system with its east/west system in southern California at different azimuths. The south-facing fit 88 modules and had a 14 percent decrease in at the 225-degree azimuth. The D Dome R² system reached 108 modules in the same space and had less than 0.1 percent change between all azimuth angles.

Solar Mounting Solutions

sms

SMS Racking consists of only three major parts that arrive with all hardware pre-inserted allowing for quick single tool installation. The THRU-ITT integrated wire management system allows wiring to remain organized and protected by running wires east-west and north-south internally. Since this racking design does not rely on the panel for integrity, installers can complete racking and wire installation independent of the panel. Twenty-year warranty.

Material: G90 coated steel and optional galvanized steel, aluminum, powder-coated. Ballast only.

How it maximizes energy density: SMS developed an Excel spreadsheet that determines the optimum row-to-row spacing based on the selected solar module, optimum tilt angle, solar azimuth angle, and the altitude angle all specific to install location. By optimizing the length of row-to-row spacers, the SMS system can greatly reduce the amount of redundant material, which in turn will reduce racking cost and avoid installing the modules in a high shadow region. The racks are designed with minimal distance between modules in the east/west direction to eliminate unused area.

Ecolibrium EcoFoot5D and EcoFoot2+

ecolibrium

EcoFoot5D 5-Degree and EcoFoot2+ 10-Degree speed installation and simplify logistics for flat-roof installs. Main components are: a base, pre-assembled clamps (integrated bonding without washers) and a wind deflector. The system is black, ASA-PC, UL Listed Resin with a 25-year warranty mounted with ballast, attachments or a mix.

How it maximizes energy density: EcoFoot5D 5-Degree delivers 18.4 percent more power than the 10-degree system and lowers cost per watt. The system maximizes roof density while maintaining the ease and simplicity of EcoFoot. The modular base is small at 7 in. x 16.7 in., and inter-row spacing is a dense 9.9 in., creating a tightly packed array. Stackable bases enable up to 290 kW per pallet, resulting in fewer pallets and minimized shipping, storage and onsite crane use.

Ask a Distributor: We ask distributors for their purchasing advice, products to watch in 2018

solar distributors

Solar is now the No. 1 new source of capacity being added to the grid, according to the U.S. Energy Information Administration, and solar installer is the fastest growing job in the country according to the Bureau of Labor Statistics. And what’s the reason for the rise of this new era? The impending doom of the ice caps melting? Hardly. The advancements in technology? Getting warmer.

Really, things just got cheaper.

This is to say that purchasing plays a large, perhaps outsized, role in the value proposition of the industry and your business. Given that reality, we wanted to kick off the year by polling a handful of solar distributors for their purchasing advice.

You’ll be hearing from:

purchasing

Here’s the No. 1 way to avoid purchasing problems

What are the common problems distributors see when it comes to purchasing systems to install? There are a few quick, solvable issues — stuff like reviewing the details of an order before signing off on it or avoiding last minute purchases.

“Plan ahead and inspect shipments to avoid/mitigate mix ups and ensure fast and timely solutions when needed,” McShea says. “Waiting three weeks until install to say something is missing and you need it now is not effective.”

But all of that feeds into the advice that resonated with us the most: Seeing the distributor relationship as a two-way street that adds value to your business. According to the distributors we talked to, the more often you communicate, the more the distributor knows about your business, the easier it is for them to help.

“Valuing price over loyalty and the quality of the relationship with a distributor, I think, is a mistake,” Schoder from Civic notes.

A simple step up in communication will not only solve a bunch of issues but could create additional value for your business.

“Good communication and transparency are always the best remedies for doing good business and mitigating potential errors,” Dufrenne says. “Everyone is busy and going to make mistakes, including distributors and shipping companies. When all parties pay attention to detail and plan accordingly, deliveries and installations seem to go more smoothly.”

And it’s not just an exercise in mistake avoidance. Keeping everyone on the same page, forecast-wise, can only make the ordering process smoother for everyone.

“At least one call a week to plan upcoming jobs would help avoid supply chain issues,” Kyler says. This ensures all orders and forecasting align with expectations.

There’s also the training aspect. “Manufacturers are constantly offering training, quite often through their distributors,” Bailey notes. “Yet we still see many installers deal with headaches for hours which they could have learned to avoid by going through some quick training on the product features and installation.”

Think about kits

Ordering from multiple suppliers for a given residential job can leave more room for error, such as damage during shipping, incorrect parts arriving or a delayed delivery, all of which lengthens install time and increases costs.

“The best solution I’ve seen yet for lowering soft costs is to have one to two standardized kits which the sales team and installation crew are both very familiar with,” says Leone with Civic. “This mitigates both sales and labor costs. We recommend having multiple kits to protect against upstream challenges such as availability.”

“Ordering from one supplier and having the experts kit the equipment per job before shipping to the jobsite or warehouse can reduce most mistakes that cause delays and additional labor/mobilization costs,” Dufrenne says.

Sticking with brands also avoids the hassle of resubmitting permits with different equipment types or brands.

4 soft cost reduction tips

Schoder: “Utilizing online software programs like Helioscope and Energy Toolbase to drastically reduce the amount of time and effort that goes into a respectable customer proposal.”

Bailey: “Smaller installers like to use microinverters for [lowering soft costs]. In many cases they don’t have the in-house expertise to properly design a string inverter system which can maximize production. Microinverters are flexible, and the installers can design in the field by adding modules as they see fit.”

Dufrenne: “Good operations management [from lead generation to final completion]. Use software, like ENACT.”

Kyler: “Installers should keep at least one administrator dedicated to handling all incoming and outgoing paperwork such as permits, SREC registrations and contracts. This would help reduce soft costs and avoid any confusion or dilemmas later on.”

Truck these rolls

For starters, it helps to have a mini-inventory of small accessories (L-feet, clamps, wire), but stocking extra parts for the rest of the system is always a good idea.

“A common purchasing mistake I see installers make is purchasing just enough for their project instead of calculating for inevitable adjustments when they get on the roof,” Kyler says. “Mostly when it comes to racking, I recommend keeping spare parts in each truck.”
Dufrenne laid it out like this: “Not ordering extra parts for racking and attachments ends up costing much more than you’d think, once you have to roll another truck and pay for overnight shipping charges for parts that are usually less than $10.”

When it comes to the inverter (and we will get into this more on page 28) MLPE or string inverters could each offer a route to reduced truck rolls, if handled correctly. But for now, we just note what Kyler recommends: “Select products that allow remote updates or choose manufacturers that provide service programs.”

“Carry spare parts and get your system up and communicating with your gateway and online account before leaving the site,” Bailey says. “Installers who use gateways can track performance as soon as the system lights up. They can coordinate with technical support and determine within a few minutes that all modules and inverters are performing to spec.”

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.
