On the Scene: 11 cool things we saw at Intersolar 2017

Another Intersolar has come and gone, but the product innovations, large and small, are here to stay. At least until next Intersolar. If you missed the event, or didn’t have time to see all three floors, here are some products that stood out to us in the exhibit hall.

1. This quick driveline disconnect

Array Technologies Duratrack

Array Technologies is the market leader in central drive solar trackers. Array tries to minimize parts count wherever it can (150 MW of PV only needing 150 components total), and we stopped by the booth to check out some of the handy new tweaks made to its DuraTrack HZ v3. In addition to a built-in above ground wiring component, we thought this quick disconnect driveline was a smart, simple improvement for those who have always wanted a streamlined way to move the driveline for maintenance activities.

2. This simple tile mounting system

Ecofasten simple tile

Ecofasten maybe wins our award for variety of new solutions packed into one booth at Intersolar. Many of these items aren’t fancy – like partnering with Unirac on an install kit (packs of 10) – but as most of the names suggest, they are simple, which is often even better. Like this new (so new it isn’t officially named) Rail-Based Tile System. The flashing itself replaces one complete tile, so no cutting, drilling or grinding there. After the stud and simple seal bushing are fastened to the tile base, place the flashing over, pound it with a hammer to form a hole over the stud and then install the L-foot with a bonded washer and nut.

3. An AC module power couple

LG enphase AC module

Details on this here.

4. The concept of ‘Microstorage’

JLM Energy

JLM Energy launched a new energy storage product category called MicroStorage — a battery pack that couples directly to a corresponding solar panel, as you see here. JLM says the advantage of its Phazr’s microstorage approach is that a single solar panel can concurrently charge a battery and deliver energy to the grid. The simultaneous nature of electron flow is unique to JLM’s patent-pending technology. The Phazr is designed for large scale solar plus storage applications, and is also perfectly suited for smaller residential and commercial installs.

5. A totally new approach to ground-mounts

Nuance Energy

This could be a gamechanger for ground-mount installations. Nuance Energy has a new solution, inspired by an old solution: anchoring. Nuance Energy wants to lessen the amount of steel needed on a site by not driving any into the ground at all. Using the pieces you see above, a hole is drilled, the anchor is driven down 40 inches into the soil and pulled by an uplift device. As the anchor turns and is pulled there is a natural ballasting that occurs using the earth itself. Utility poles are anchored using this strategy. This could drastically save on traditional installation, and even created a new “lift and shift” category, where a portable unit is fixed into place on a drilling or mining site and then removed once the project has ended.

6. This wall-mounted 100-kW inverter

solaredge

The combo EV charger / inverter maybe received the most buzz on the floor, but we gravitated to its new wall-mounted 100 kW inverter. Yes, a wall-mounted 100 kW inverter. This prewired three box setup looks like (and installs like) three string inverters, but is commissioned as one inverter. Installing 1 MW in half a day is a possibility.

7. The wire management on this tracker

SF7 Soltec Bluxome party

Soltec made a splash at Intersolar this year as it tries to do more business here in the U.S. There is a lot to like about their product, like the amount of panels you can mount in one row (which makes for a more energy dense field), but it was the little things that stood out most. Specifically how the wire management of the system is housed inside the torque tube.

8. The potential of this smart home device for solar installers

smappee solar storage

I have no live photo of this (it was the afternoon of Day 3 and I forgot — give me a break, already.) but the Smappee is the coolest thing we saw the entire week. Attach it to the cable coming into the house, and the Smappee will listen to everything – what’s turning on and off, how much standby power there is, how much PV is being generated, and on and on. This gives homeowners much deeper (and easy to follow) insight into their home energy consumption and, at the same time, provides solar installers another touch point for customer follow ups and service. The low price point (under $400) makes it potentially an easy first foot in the door. Right off the bat, a homeowner is likely to save 12 percent on their utility bill, just through awareness and optimization tips from the app. From there savings could approach 45 percent.

9. This stepped-up decentralized tracker

solar flexrack tracker turnkey

Solar FlexRack launched its TDP Turnkey Tracker about this time last year. The update for this year is a newer, longer single row tracker (90 modules with 2 to 4 more posts), adjusted by a larger motor that will open up larger, utility-scale projects. The torque tube is offset to achieve better balance. The attention to detail is big for Solar FlexRack, which is why “turnkey” is built into this product’s name – its slew of engineers are involved in their installations to avoid adding their company name to the list of growing tracker system failures out in the field.

10. This tripod tile mount

Sun Modo tile

Sun Modo tripod

The last few years has seen a flood of great tile roof mount solutions enter the market. The TopTile Mount that SunModo debuted at Intersolar is an entirely above-the-tile system – no need to deconstruct the tile roof. The tripod mounting stanchion can be mounted on a tile ridge independent of rafter position. This could cut your install time in half, compared to a more conventional approach.

11. Smart surge software

Tabuchi Americas

Now with a two-battery system setup, Tabuchi Americas continues to improve upon its solar+storage system (now more than 20,000 installs worldwide). Thanks to an integrated transfer switch, everything needed to get a PV + storage system up and running is included in the package, which means at least $1,000 soft cost savings over an unbundled system. In fact, this is one of the first UL 9540 certified systems – the certification specifically for solar + storage systems. Updates to the system’s intelligence has also improved its defenses against power surges from things like water pumps.
