U.S. Defense Department commits to solar power production across several sites

The Defense Department has been installing solar at military bases at a fairly steady pace the last few years. The most recent projects coming online soon include a large Gulf Coast Solar Center portfolio (across three sites) and a new solar + storage system at a post in Alabama.

Here’s the scoop on those.

Gulf Coast Solar Center

Coronal Energy, powered by Panasonic teamed with Pensacola-headquartered energy provider Gulf Power on the largest combined portfolio of solar facilities on Department of Defense property to date. The 120 MWac Gulf Coast Solar Center spans 942 acres across three Navy and Air Force sites in Northwest Florida.

The Naval Air Station (NAS) at Pensacola’s Navy Outlying Landing Field (NOLF) Saufley hosts the largest of the three solar installations: a 366-acre, 50 MWac solar generating facility. The solar facility at NAS Pensacola’s NOLF Saufley comprises nearly 600,000 solar PV modules that will generate enough energy to power approximately 7,400 homes in Northwest Florida annually. The three-project portfolio, representing one of the largest combined solar projects east of the Mississippi, also includes 40 MWac and 30 MWac facilities at NAS Whiting Field’s NOLF Holley and the Eglin Air Force Base Reservation spanning 336 and 240 acres, respectively. In total the nearly 1.5 million solar panels generate enough energy to power more than 18,000 local homes each year across Escambia, Santa Rosa, and Okaloosa counties.

“Considering the scale of the Gulf Coast Solar Center portfolio, collaboration between our team and the like-minded teams at the U.S. Air Force, U.S. Navy, and Gulf Power has been an essential element of our success in developing these projects,” said Jonathan Jaffrey, chairman and CEO of Coronal Energy™. “The result is a landmark energy project that represents what is possible when our nation’s military and its leading energy companies like Gulf Power commit to renewables. We are honored to take our place alongside these partners for this historic project.”

“Each installation and mission throughout the Southeast is unique and it is imperative for us [the Navy] to have the energy security and resilience needed to support the greater Navy mission. There are eight renewable generation projects that DON is supporting in the southeast and today you are seeing the completion of two solar facilities in Northwest Florida totaling 122.5 megawatt direct current,” said NAS Pensacola Commanding Officer Capt. Christopher Martin. “We are pleased to know these facilities will help provide clean energy to thousands of homes across Northwest Florida.”


Alabama Army post adds solar + storage

SunPower Corp. has broken ground on a 10-MW solar  system at the Redstone Arsenal U.S. Army post in Alabama and will combine with a newly added 1-MW energy storage system to strengthen energy security and resilience at Redstone Arsenal.

Developed by the U.S. Army Office of Energy Initiatives, Redstone Arsenal’s Directorate of Public Works, and the U.S. Army Corps of Engineers Huntsville Center’s Energy Division, the project was financed by a power purchase agreement (PPA), allowing the Army to buy 100 percent of the power generated without having to pay for the power plant’s construction, maintenance and operation. The Army continues to collaborate with private-sector partners and utilities to build clean, alternative energy projects including onsite power generation, electricity storage, and energy control.

“Solar is cost-competitive with traditional energy sources today, and is helping the U.S. military reduce operational costs,” said Nam Nguyen, SunPower executive vice president. “We commend Redstone Arsenal for managing its significant energy demand with abundant, renewable solar power. The high performance solar and storage technology we are installing for the agency will substantially increase the value of energy produced by the solar plant over the long term.”

How one PV module manufacturer wants to meet the needs of homeowners

Solaria uses a direct contact between cells

Solaria uses a direct contact between cells to reduce power loss as well as achieve an all-black look.

For all of the intrinsic value of solar, selling it on a wide-scale to homeowners might depend more on stuff like emotional appeal and aesthetics. This is driving the influx of black PV panels coming onto the market. LG’s NeON series comes in black. Panasonic just released all-black versions of its popular HIT panels (as we noted last issue). And so on.

A new entrant into this space is Solaria, a technology company that has been developing its technology over the last decade to commercialize a breakthrough product for the industry. As Chinese panels continued to drive down prices in utility-scale projects, that market became less of a focus.

Looking at the market, Solaria CEO Suvi Sharma thinks residential installs are the next big opportunity for high-efficiency, aesthetically pleasing panels that have residential applications in mind from the start.
“If you look at the Chinese model of panels where you basically make two different sizes that you stuff into different channels, that worked when the market was small, but now the market deserves its own product and focus.”

Solaria took its core technology – solar cell cutting, handling assembly and automation and configured a module and design to do two things:

“Produce significantly more power than a standard solar panel using the same bill of materials and, just as importantly, provide a much better looking panel,” he says. “With the industry maturing, those attributes will become more important. We want to break through from the early adopters in the mass market.”

Right now, Solaria’s residential solar capacity is still on the smaller side. Between its line in Fremont, Calif., and its line in South Korea, Solaria is working on adding additional capacity to meet growing demand.

Inside the Design

Conveniently, Solaria’s strategy for designing an efficient panel naturally created a sleek-looking product. The Solaria formula in a nutshell is to cut solar cells (mono PERC) into five strips and then overlap each of them instead of interconnecting them with traditional ribbon wire. The cell architecture of a traditional module leaves dead space between each cell, whereas this overlapping structure creates a uniform, continuous string of strips as well as the aesthetic bonus of covering up the typically visible busbars.

“All of the active areas of a cell are exposed. Busbars on a typical module shade about 3 to 4 percent of the module and cell, so we eliminate that through the overlap mechanism,” he says. “By creating a direct contact between one cell and another, we get better electrical performance because we don’t have the traditional losses associated with ribbon wires.”

Why high-efficiency modules are the best value for installers, homeowners

Part of the value from increasing system efficiency within the module architecture itself — and wiring in a combination of parallel and series — is also reducing the need for efficiency-boosting or shade-mitigating MLPEs. You may still want to incorporate optimizers in certain applications, but the need is reduced.

Add all of that up, Sharma says a Solaria panel (60-cell, 330 Wp) should be expected to produce 15 to 20 percent higher power than conventional panels using the same cells and materials to pair with that all-black appearance. The price point for Solaria is higher than a conventional Chinese panel, but priced below a high-efficiency SunPower back-contact panel.

Looking Ahead

Beyond improved aesthetics, simplicity is another big factor in the residential market. For that reason, Sharma wants to put Solaria on the path toward smart AC modules.

“How does solar become truly mainstream? The installation of the system needs to be simplified more and more. Plus, it’s a complex sell. The broader we can make the installer base, where more electricians get into it, the bigger it’s going to grow. We want to simplify the installation and that’s where we see the opportunity for integrated AC modules.”

Be on the lookout for more news on that front from Solaria as it tests out concepts with various microinverter manufacturers until it feels comfortable enough to offer an integrated product and stand behind the warranty.

Why Mono PERC?

Key to Solaria’s solution is the mono PERC cell. CEO Suvi Sharma explains his reasoning behind that choice.

“You typically get about 1 percent absolute improved power today from a standard mono cell, but the roadmap to improve that power is better with mono PERC,” Suvi says. “There are more dials to play with in terms of efficiency. Not only does mono PERC have higher power than a traditional mono cell, but the difference is going to grow over time. Could become 2 percent absolute over the next 18 months.”

“One issue with PERC is its light-induced degradation [LID]. The PERC manufacturers have worked on that a lot over the last 18 months. The LID is similar to mono cells now. Sometimes in multi PERC there tends to be more LID.”

“Mono PERC is growing in market share because it’s an add-on. If you already have an investment in a mono cell line, you can leverage it for mono PERC as opposed to new cell contents like heterojunction and bifacial, which require a fundamentally new investment in equipment. We believe that within three years probably, all mono cell capacity is going to be converted to mono PERC.”

Panasonic names its first group of Premium Solar Installers

Panasonic solar solutions

Several authorized installers of Panasonic’s HIT solar modules were just promoted to the exclusive “Premium Installer” status. Panasonic unveiled this program last year to provide valuable assets to partners who meet Panasonic’s high standard of excellence.

“The growth of Panasonic HIT modules across North America has allowed us to partner with several exemplary solar panel installers who share the same dedication to quality customer service and superior product performance as we do,” said Mukesh Sethi, Group Manager of the Solar Division of Panasonic Corporation North America. “We are thrilled to offer additional benefits to these valued partners and we look forward to working with them for years to come as we expand our presence in the North American residential solar market.”

Those partners are… (drum roll, please)…

• Sullivan Solar Power – San Diego, CA
• LA Solar Group, Inc. – Van Nuys, CA
• Westhaven Solar – Santa Cruz, CA
• Sierra Pacific Home & Comfort – Rancho Cordova, CA
• Diablo Solar – Martinez, CA
• RevoluSun – Burlington, MA
• SUNation – Ronkonkoma, NY
• SunRay Solar – Concord, NH
• NJ Solar Power – Bayville, NJ

What’s a premium installer?

Panasonic’s Solar Installer program is comprised of “Authorized” and “Premium” installers. Premium installers are those companies that have completed a minimum requirement of HIT module installations and have met an annual wattage target. These installers also promote Panasonic as their primary brand of solar modules, and they receive a range of benefits from Panasonic to enhance their offerings to customers.

Premium installers will be part of continuous efforts with Panasonic to promote the HIT brand among the installers’ area of operation. They will receive leads generated through Panasonic’s website, where the installer will be listed as premium. Premium installers are also the beneficiary of cooperative marketing funds provided by Panasonic, at twice the level of funds provided for Authorized Installers, to help grow their business and attract even more customers.

Panasonic will aim to expand the reach of the Solar Installer program and bring industry leading companies into these mutually beneficial partnerships.

Renewable energy project in Colorado draws interest from Department of Energy

The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) is partnering with Panasonic Corporation and Xcel Energy to simulate and optimize the energy load profile of Peña Station NEXT, a planned 382-acre mixed-use development in Denver, Colo.

The project will employ the grid modeling capabilities of NREL’s Energy Systems Integration Facility (ESIF) while demonstrating URBANopt software, a buildings and district energy modeling tool currently under development at NREL. Through this project, NREL hopes to enable a cost-effective, scalable net-zero development infrastructure that has great potential for replication and adoption across the U.S. in future developments.

Pena station panasonic solar project

“The NREL partnership with Panasonic and Xcel Energy helps deliver on our shared vision for clean, affordable, and reliable energy systems at a pace and scale that matters for our society,” said Juan Torres, NREL’s associate laboratory director for energy systems integration. “As a national user facility, the Energy Systems Integration Facility at NREL is an ideal place for both Panasonic and Xcel Energy to analyze and optimize the project’s energy master plan before construction, in a way that benefits all involved.”

The project uses URBANopt to analyze the projected dynamic energy consumption of corporate office space, retail space, multifamily dwellings, a hotel, parking, and street lighting within the planned development. The data will then be integrated into Xcel Energy’s grid distribution modeling tools to create a cost-effective design framework that the utility and developer can use to integrate more distributed energy resources, such as solar photovoltaics or efficient building systems, and innovative rate structures into the development before it is constructed.

DOE prioritizes solar power plant performance with Power Factors funding

The partners are confident the project holds great promise beyond Peña Station NEXT’s borders. Xcel Energy will consider owning and operating the necessary infrastructure to achieve carbon neutrality, potentially expanding the offering to future communities in Colorado. Panasonic is similarly interested in how it might replicate and scale carbon-neutral districts and developments across its other current and future smart city engagements through Panasonic CityNOW. NREL will share its expertise and apply the lessons learned from this project to future developments.

NREL’s ESIF is a flexible and fully integrated lab space dedicated to testing residential and commercial smart energy technologies. It is a one-of-a-kind testing space that connects appliances, electric vehicles, a home, or even a community to an end-to-end energy ecosystem. By incorporating power generation, energy storage, and dynamic energy loads into the facility, researchers can simulate and optimize real-world conditions in a controlled laboratory environment.

NREL is the U.S. Department of Energy’s primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for the Energy Department by The Alliance for Sustainable Energy, LLC.
