Quote from www.greentechmedia.com

He’s a big man living in a big house. It’s fitting that he gets a big solar system on his roof. NBA legend (and NRG Home Solar spokesperson) Bill Walton just went solar on his residence in Southern California.

Here’s what we know about the system: It’s a 12-kilowatt rooftop power plant using Enphase microinverters, Unirac racking systems, roof mounts from Quick Mount PV and 43 solar panels from LG. Walton had told the installers that he wanted panels “everywhere.”

Unirac Awarded Contract for 6.4 MW DC Roof Mount (RM) Installation on Mandalay Bay Resort and Casino Convention Center, Las Vegas, NV.

By | News Release | No Comments

ALBUQUERQUE, NM – October 23, 2014 – Unirac, Inc., a Hilti Group Company and leading provider of high quality, competitive PV mounting solutions in North America, has been selected by NRG Energy (NYSE: NRG) to provide a 6.4 MW DC Roof Mount (RM) for installation on the Mandalay Bay Resort and Casino Convention Center in Las Vegas, Nevada. Mandalay Bay, owned and operated by MGM Resorts International (NYSE: MGM), is MGM Resorts’ first commercial solar project in the United States.

MGM Resorts selected the Mandalay Bay Resort & Casino Convention Center because of its large south facing rooftop space with roughly 20 acres of optimal surface for solar power production. The completion of the project was announced today, and the rooftop installation will produce 20% of Mandalay Bay’s power demand at peak production.

“When designing one of the largest contiguous rooftop solar installations in the world, racking performance, site logistics and project planning are extremely important,” said Todd Kerschbaum, CEO at Sunora Energy Solutions, the firm responsible for installation. “Unirac’s performance on this project was exemplified by their commitment to delivering products on time, while maximizing our field productivity through efficient product design.”

ROOF MOUNT introduces the Power of Simplicity to the ballasted, flat roof solar industry. The system consists of only two major components, minimizing preparation work and installation time. RM allows installers to seamlessly design around roof obstacles, support most framed modules and bond the system with just the turn of a wrench.

“Our mission is to deliver high-quality solar solutions at the lowest total installed cost, RM is no exception,” said Michael Kennedy, Unirac Vice President of Sales and Marketing. “We are excited to expand our partnership with Sunora and NRG on another high profile project such as Mandalay Bay.”

Unirac Partners with Enphase Energy to Eliminate Copper Wires and Grounding Lugs in Solar Installation Process

SolarMount enhancements featuring pre-assembled components and new grounding process launching at Solar Power International

ALBUQUERQUE, N.M., Oct. 20, 2014 – Unirac, Inc., a Hilti Group Company, announces a new milestone in the continued evolution as the leading provider of high quality, competitive PV mounting solutions in North America. Today, Unirac’s SolarMount system becomes the first residential PV mounting system in North America to provide a revolutionary grounding and bonding process listed to UL2703 that eliminates the need for copper wire and grounding straps from the installation process.

“In a market driven by cost, this method of grounding an array further simplifies installation, enhances safety, and saves on labor and materials costs,” said Peter Lorenz, CEO of Unirac. “The partnership between Unirac and Enphase is a signal that, as leaders of the industry, we need to harness the full potential of cost savings by working together”

SolarMount’s mounting technology when used with Enphase Energy® M215 and M250 Microinverters, meets all grounding and bonding per UL2703. SolarMount’s components feature integrated bonding from the top module clamps to the L-foot, creating a tested bond between the systems modules, racking and microinverters. The Enphase Microinverter’s DC circuit is isolated and insulated from ground, eliminating the need for copper wire.

“Since Enphase introduced integrated ground capability for the M215 and M250 microinverter systems, solar contractors have benefited from shorter installation times, lower copper and other materials costs, and improved safety conditions,” said Martin Fornage, chief technology officer of Enphase. “The UL-listed solution pairing Unirac’s SolarMount with Enphase’s integrated ground technology will provide even more cost-reduction efficiencies to our installation partners.”

All SolarMount integrated bonding components have been extensively tested by TUV Reinland Group, a leading provider of technical services worldwide, and listed to UL2703.

Unirac is introducing new enhancements designed to get installers off the roof faster than ever before. SolarMount’s pre-assembled and integrated bonding mid clamp provides module-to-rail bonding by utilizing patented top mounting technology to penetrate through the anodized finish of rail for a continuous bond through the array, eliminating additional hardware. An integrated bonding splice eliminates bonding jumpers or grounding straps to electrical bond rails across the splice, reducing installation steps and copper to shave total installed cost. Installers can seamlessly fasten the microinverter anywhere along the top of the rail while creating an electric bond.

Unirac is celebrating 15+ years of solar racking innovation at Solar Power International 2014. For more information about Unirac’s full line of innovative PV mounting solutions, please visit us at Booth 306, October 21-23, 2014 in Las Vegas, NV.

DNV GL verifies Unirac’s Roof Mount (RM) Installs at 12 Modules Per Man Hour

By | News Release | No Comments

ALBUQUERQUE, NM – July 8, 2014 – Unirac, Inc., a Hilti Group Company and leading provider of high quality, competitive PV mounting solutions in North America, is proud to announce we received 3rd party verification that Roof Mount’s installation speed is 12 modules per man hr., an industry leading standard.

PV Evolution Labs (PVEL), now DNV GL, conducted a photovoltaic (PV) module installation time-trial of Unirac’s RM Roof Mount racking system. The time trial evaluated the installation efficiencies of the RM Roof Mount system both qualitatively and quantitatively. Qualitative information included installer feedback. Each installation of the three (3) identical systems was timed to establish successive installation metrics.

Installers find RM’s ease of installation to be more favorable when compared to competitive products. System grounding is efficient with grounding at a single point, a large contributing factor to installation speed.

The installation crew had previous experience installing flat-roof PV module mounting systems but no previous exposure to Unirac’s RM Roof Mount system prior to this study. The only resource used by the crew was the RM Roof Mount installation manual; improving their learning curve over the three installations.

“RM has been proven to be the fastest flat roof solution on the market today, this is an essential component in helping our customers build successful solar projects,” said Michael Kennedy, Vice President of Sales and Marketing. “Step by step third party installation data takes the guesswork out of installation costs for our customers. Best of all, these metrics beat all competitive marketing claims, saving our customers time and money on the job site.”

ROOF MOUNT introduces the Power of Simplicity to the ballasted, flat roof solar industry. The system consists of only two major components, minimizing preparation work and installation time. RM allows installers to seamlessly design around roof obstacles, support most framed modules and bond the system with just the turn of a wrench.

Seismic Guidelines for PV Installations

By | Events | No Comments

Written by Anne Fischer

The Los Angeles Community College System in California (US) was all set to go with a huge solar installation, but the designs were scrapped because the arrays were going to be built above seismic faults. The problem may not have been that installing solar equipment in seismic areas is inherently life threatening, but rather that engineers and code enforcing agencies had nothing to go by in ensuring the safety of such systems. Fortunately this is changing. The Solar Photovoltaic (PV) Committee of the Structural Engineers Association of California (SEAOC) is a group of PV specialists who have been working on the development of standards for solar arrays in earthquake-prone regions, the results of which will likely have broad impact throughout the industry. – See more at: http://www.solarnovus.com/seismic-guidelines-for-pv-installations_N7868….
