When Saturn Solar Bermuda faced the challenge of maintenance and replacing and recycling multiple solar panels and inverters at their site on an old landing strip at LF Wade International Airport, they turned to Bluewater Battery Logistics for a solution. This case study explores how utility scale solar maintenance may require global access to replacement parts and recycling facilities, spanning three countries, utilizing both land and sea shipping, and ensuring compliance with all international regulations.
The Challenge
The project involved replacing and shipping out for recycling a few hundred Znshine ZXP6-TLD72-325 solar panels and custom-sourcing similar or matching replacement panels. The replacement panels needed to match or exceed the voltage and power requirements of the existing system, while also being of similar dimensions to ensure compatibility.
Additionally, Saturn Solar needed to source Huawei 45KW inverters, which had been manufacturer-discontinued for two years by that time, making them difficult to find in new condition. The logistical challenge was compounded by the fact that shipping to and from Bermuda could only be done using 20-foot containers through New Jersey, the primary port for shipments to the island.
The Solution
Bluewater Battery Logistics began by sourcing the replacement solar panels, which they found in Texas, USA. The chosen GCL panels had a power rating of 370W, slightly higher than the existing panels, 1500V, and dimensions of 1956x992x35mm, making them compatible with the existing solar array.
Bluewater was also able to locate the discontinued inverter Huawei 45KTL-US-HV-D0 model from surplus stock in Alberta, Canada. This required a huge partner network and careful negotiations and vetting to ensure that all components were in mint condition, crucial for the solar system's performance.
Once the components were sourced, Bluewater coordinated the shipping logistics. They custom-packaged the new panels and inverters for transport in 20-foot containers, the only size permissible for shipping to Bermuda. The old Znshine panels were shipped back to New Jersey in the same containers for recycling at a certified plant.
Managing the entire project under one contract allowed Bluewater to streamline operations and project management on the customer’s side. They took charge of all necessary paperwork for international shipping, ensuring compliance with regulations across the three countries involved in the project: the United States, Canada, and Bermuda.
A Successful Outcome
Bermuda Airport Solar Project at LF Wade International airport is a unique installation on an old airport runway not in use. A subsea cable is used to connect it to the main grid and feed its 6MW of solar-generated clean power. Inexpensive solutions for solar panels replacement and repowering involving complex cross-border logistics became key for keeping Bermuda Airport solar energy affordable and accessible.
“Bluewater Battery Logistics not only managed to source solar system elements matching our unique parameters, including discontinued inverter models, but also handled international shipping and recycling of the old panels. Everything was managed as one project by one team—this is unique in our industry!” said Mike Gupta, VP of Operations & Maintenance at Saturn Solar.
Expertise in Action
This case study underlines the importance of logistics efficiency, custom-sourcing specialized components, and compliance with regulations for shipping and recycling of energy systems. Especially for utility scale projects like Saturn Solar Bermuda with its complex island logistics.
Steve Feinberg, President of Bluewater, noted, "Bluewater has a truly unique global network of partners and vast experience with international shipping. We make it simple to work with us, keeping the whole project under one contract."
In a world where renewable energy solutions are already a major part of energy systems, projects like this highlight the importance of collaboration and commitment to solar equipment circularity. Bluewater Battery Logistics is facilitating the global energy transition by making solar technology more affordable and easier to maintain.

A state of emergency was declared in Northern California following a fire at the world’s largest lithium battery storage plant earlier this year. Packaging And Crating Technologies (PACT), a Connecticut manufacturer of fire-suppressant paper wrap is ensuring that this never happens again! The innovative family-owned business recently presented its life-saving product line that prevents and extinguishes lithium battery fires at the International Battery Seminar & Exhibit in Orlando, Florida. Specifically, PACT COO Rodger Mort conducted an informational session for thousands of consumers, automotive, military, grid, and industrial professionals.
![]() |
“Our booth was swamped with hundreds of visitors each day who work within the battery and EV tech communities,” said Rodger Mort, chief operating officer at PACT, LLC. “We addressed the hot topics of how to safely charge, transport and recycle lithium batteries that are used to power a variety of E-mobility equipment and handheld devices.”
Mort explains that the company’s signature product- PACT Thermo Shield was invented as a thermal management system for shipping and storing items containing lithium batteries. It consists of three thin, lightweight, paper materials coated with proprietary ink. When a lithium battery goes into thermal runaway and burns, the special ink releases a moisture barrier that creates a vapor cloud to immediately cool the internal contents of the package to prevent a domino fireball effect, while limiting oxygen around the package to prevent the battery temperature from escalating to 1,500° Fahrenheit, at which point, lethal gases form.
From the same technology, PACT also developed a 100% paper-based solution for lithium-ion battery packs, called TR Sleeve that shuts down thermal runaway on the cellular level, as well as TR Envelope, which safely transports and stores smaller devices such as cell phones, pagers, smartwatches and rechargeable A-D batteries, items becoming a hazard for commercial airlines during flight.
Lastly, Mort discussed the company’s newest invention – the PACT Lion-X Fire Extinguisher, which is still undergoing testing requirements but is targeted to be available by end of the year. The pre-mixed, water-based solution quenches lithium battery fires upwards of 1,600 degrees within seconds, while eliminating the release of toxic gases into the environment and is the first of its kind on a global scale.
“The PACT team was very well-received at this venue as lithium battery safety is a serious global issue,” adds Mort. “As new electronic devices continue to enter the market, we are committed to educating industry peers, business owners and consumers on the proper way to handle, charge and recycle these items.”
As the longest-running annual battery industry event in the world, the International Battery Seminar & Exhibit has always been the preferred venue to announce significant developments, new products, and showcase the most advanced battery technology. In fact, Sony chose the International Battery Seminar as the platform to first announce its lithium-ion technology in 1991, an accomplishment that has since gone on to change the world.

Onyx Renewables, a national provider and owner of localized clean energy solutions, celebrated the groundbreaking of a 2.5-megawatt (MW) onsite solar project with Sol Systems, the initial project developer, and Verde Solutions, the engineering and construction company for the project, marking the start of major upgrades at an Urbana and Champaign Sanitary District (UCSD) wastewater treatment facility in Illinois.
The solar project, set to begin construction this spring, will feature a ground-mount array that generates clean, affordable power for UCSD's southwest wastewater treatment plant. Once complete, the onsite solar energy system is expected to produce over 4,100,000 kilowatt-hours in the first year of production. Any excess power will be used as credits to further offset UCSD's power costs. This project highlights Onyx's commitment to developing onsite solar in the Midwest, where programs like Illinois Shines provide incentives that create well-paying jobs for Illinoisans and cut energy costs for customers.
Onyx will complete development, oversee construction, finance, own, and operate the onsite solar energy system, providing UCSD with stable, low-cost electricity through a long-term power purchase agreement. Onyx will also monetize the project's renewable energy credits (RECs) as part of the Illinois Shines REC program. Sol Systems originated and initially developed the project in 2022 before transferring it to Onyx. Verde Solutions will serve as engineering, procurement, and construction (EPC) partner, handling the design and permitting of the project. The system is expected to be operational by the end of 2025.
"Building on our extensive experience with water and wastewater treatment facilities, Sol Systems is proud of the partnership built with UCSD over the last few years as we developed this project. Onsite, this project will generate local, fixed price electricity, helping manage costs for UCSD for the next 15 years," said Anna Toenjes, Associate Vice President of Impact & Business Development at Sol Systems. "Offsite, Sol Systems will establish a scholarship in partnership with Parkland College to reflect our broader commitment to making a positive difference not only through energy projects but also by investing directly in the communities where we work."
"This project exemplifies Onyx's value as a partner throughout our customers' clean energy journey. We've been able to tailor our approach to UCSD's needs to ensure that the end result delivers on what matters most to our customer: cost savings and reliable clean power for Illinoisans," said Kevin Cox, SVP of Origination at Onyx. "Our relationship doesn't end there, either — long after construction is finished, we'll be with UCSD every step of the way as the long-term owner and operator to deliver consistent, reliable electricity to its facility."
"Since our founding, UCSD has sought out economical and reliable energy solutions for our facilities. We were very pleased with Sol Systems' work to initially develop the project. Now, Onyx is a critical partner committed to building a high-quality, well-maintained solar solution that will be part of a state-of-the-art facility which will fit in with residential and park facilities as neighbors," said Rick Manner, Executive Director at UCSD. "With the Solar Power Purchase Agreement, and requiring no up-front investment from UCSD, about 85% of our southwest plant's electric usage will be generated onsite. The price for the clean power is fixed at a low rate that will allow us to see considerable savings for our facility's budget. Our ratepayers will enjoy this benefit from the cost savings for at least the next 15 years."
This onsite solar project is part of a larger $35.9-million expansion and upgrade of UCSD facilities funded by a low-interest loan from the Illinois Environmental Protection Agency and slated for completion in 2027.
