Nuance Energy installs 530-kW system at Flag City RV Resort thanks to unique anchor ground-mount

Nuance Energy, manufacturer of the patent-pending Osprey PowerPlatform and developer of distributed generation solar projects through its Central Valley California AgWell Solar division, has installed 530 kW of solar power at the Flag City RV Resort in central California. Nuance Energy handled the installation directly owing to the project’s complexity, which involved rooftop, carport and ground mount solar arrays, as well as both state and local permitting requirements.

“Flag City RV Resort is proud of our highly efficient solar initiative, which reflects both our financial responsibility and environmental stewardship,” said Ricky Gill, the resort’s co-owner. “As one of the top-rated RV resorts in the U.S., we strive for excellence and believe this is a project our peers will seek to emulate. Thanks to our close partnership with Nuance Energy, we successfully completed this project that involved several challenges and multiple jurisdictions.”

Site challenges

Among the challenges were the undocumented underground services, the site’s 15-degree slope, and the constant traffic in and out of the resort. The Osprey PowerPlatform’s use of Nuance Energy’s innovative earth anchor foundation system easily overcame all three of these challenges based on its minimal ground penetration, adjustable anchor stands and the lack of need for any heavy equipment, including pile drivers, screw augers, backhoes or cement trucks.

Additional value

The installation was “green” for another reason, as it enabled Flag City to switch to a more favorable rate from the local utility, which eliminated the high demand charges with the previous rate. Those savings, combined with the daily offset of energy needed from the grid and tax considerations, result in an estimated payback in the fourth year of operation.

“Continued reductions in the cost of solar modules and inverters have made the business case for solar energy far more compelling for virtually all businesses,” said Brian C. Boguess, Nuance Energy’s co-founder and CEO. “Nuance Energy is making solar energy even more viable and affordable with the use of an earth anchor foundation system and related innovations that together provide the industry’s lowest installation cost for ground mount projects, including those like Flag City’s that present difficult challenges.”

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.

Inverter manufacturer Tabuchi invests in ground-mount developer Nuance Energy

Nuance Energy, the manufacturer of the Osprey PowerPlatform and a developer of distributed ground-mount solar projects, today announced it has received a $3 million investment from Tabuchi Electric Co. LTD.

The two companies already have a close working relationship. Nuance Energy, an early North American customer for Tabuchi, has installed the company’s commercial string inverters on several projects. Working together on these projects led Tabuchi Electric to discover the strategic advantages afforded by the Osprey PowerPlatform. The companies plan to continue working together to find synergies benefiting customers that use Nuance’s Osprey PowerPlatform and Tabuchi’s commercial products.

Tabuchi- Electric EIBSinverter crop

Tabuchi Electric made the investment in Nuance Energy to expand its learning and reach into the growing market segment of ground-mount distributed generation Solar+Storage. Tabuchi, already present in the residential Solar+Storage market with its EIBS, plans to expand its storage offerings to the commercial market and expects to gain valuable insights from the relationship with Nuance Energy to further drive innovation.

“As a leading provider of grid-friendly solar-plus-storage systems optimized for energy management and cost performance, we were early to recognize that Nuance Energy’s unique value proposition would give us a significant advantage in commercial applications,” said Harumi McClure, COO and pres-ident of Tabuchi Electric Company of America, LTD. “Together our companies will expand the available market for solar and open up more project opportunities for our mutual distributor and EPC contractor customers.”

Nuance Energy’s Osprey PowerPlatform is a modular ground-mount solar racking system that applies patent-pending technology to afford numerous advantages, including simplified engineering, adding modularity to the procurement process, and dramatically reducing construction costs and effort. The Osprey PowerPlatform employs a unique, minimal earth-penetrating anchor application process and a modular, scalable design that enables contractors, developers, integrators, and engineering, procurement and construction (EPC) firms to achieve peak profitability through the industry’s lowest labor and installation costs and fastest time-to-revenue for available ground mounted system solutions.

What you need to know about 1500-volt inverters

Unlike conventional ground mount systems that require a detailed geotechnical report, extensive engineering effort involving the use of ground screws and pier foundations, and costly construction techniques that require heavy onsite equipment, the Osprey PowerPlatform enables field crews to install the solar arrays using only handheld tools. The design also eliminates the need for special inspections by facilitating simple field load testing in real-time soil conditions to assure compliance with applicable codes and regulations. This ability to deploy solar arrays on varied terrain under any type of soil condition helps make solar energy more practical and affordable at any scale, and creates more opportunities for agricultural, commercial, industrial and small utility-scale projects.
