Solar is safe when it’s maintained — and risky when basics slip. Across sites, the pattern behind many PV fires is consistent: soiling and shading create hot spots; loose or corroded DC joints run hot; wildlife and litter add fuel; and moisture inside isolators or combiners encourages tracking and arcs. Temperatures rise, combustibles build, and one imperfect connection becomes ignition. How PV fires actually start On the DC side, m....

Embedded into a mountainside in Adjuntas, Puerto Rico, a new agrivoltaics system could set standards for energy independence in hurricane-prone regions. This system was realized through a collaboration between solar professionals, energy manufacturers, and a family-owned coffee farm. MT Solar is proudly included among its contributors.
Hacienda Berdiel Torres owner, Miguel Berdiel, was dealing with multiple obstructions on what should have been a prosperous farm. Despite optimal coffee-growing conditions and a hydroponic greenhouse, high energy costs and other impacts from Hurricane Maria were stifling growth. The greenhouse's hydroponics system was eventually shuttered, and plans to offer jobs and locally grown food to the community were halted.
Hacienda Berdiel's challenges and potential as an agrivoltaics research and climate resilience project aligned with the NREL's InSPIRE initiative. The organization tapped Oregon-based nonprofit, Twende Solar, to plan and coordinate the installation.
Twende Solar approached MT Solar to design top-of-pole mounts that could be safely and efficiently installed at a 3000-foot elevation and accommodate all farming operations. The system also needed to resist hurricane-level forces and provide enough capacity to secure Hacienda Berdiel's energy resources.
"With such high wind loads, we had to tackle some challenges to get a design that allows for high ground clearance above coffee trees. It's exciting to help our customers achieve their needs even in extreme conditions," Jamie Blum, MT Solar's design and sales engineer, explained.
The 9.8kW system was installed in July of 2025. MT Solar subsidized six solar mounts, each holding four 410W modules 15 feet above the ground. Aireko Energy Group and GRID Alternatives Puerto Rico completed the foundation and system assemblies. Texas-based energy storage manufacturer, EG4 Electronics, donated the inverter and batteries for a 40kWh energy bank.
With the system running, Hacienda Berdiel now plans to reopen its greenhouse. Despite energy costs and an unpredictable climate, energy resilience and independence are within its reach.
This system could define standards for ground solar in hurricane-affected regions. To help build a blueprint for comparable installations, researchers will monitor system output and crop productivity over the next two years.

With X.Cellify DC, Dürr has developed a new kind of dry coating for electrodes: a free-standing film of active material is created that is 100% recyclable until it is laminated onto the collector foil. This significantly reduces active material waste. The proof of concept for the process shows that the technology works reliably and is scalable. This paves the way for pilot projects on a gigawatt scale – initially for lithium-ion batteries and, in the future, for solid-state batteries as well.
Electrode production has so far relied almost exclusively on wet coating, in which the cathode and anode material is applied as a solution to metal foils and then dried in an energy-intensive process. The technology developed by Dürr in collaboration with partners does not require solvents or drying ovens, as it produces the electrodes from a dry powder mixture. The dry battery material is pressed into a film using the Activated Dry Electrode® process by development partner LiCAP Technologies. The new X.Cellify DC development covers all process steps – from dosing, film formation, and densification to lamination onto the collector foil.
Less energy, less production space
Dry coating offers clear advantages over conventional wet coating in electrode production: it reduces space requirements by up to 65% and lowers energy consumption by up to 70%. These savings are mainly due to the elimination of dryers and solvent recovery. "The successful proof of concept is a major step forward for us. We have demonstrated that the new kind of dry coating with free-standing film works reliably and delivers consistently good quality. It can be scaled up, making it the basis for initial pilot projects in industry," explains Bernhard Bruhn, Vice President of Dürr's Global Business Unit LIB. The process is suitable for today's lithium-ion batteries and also for solid-state batteries.
Free-standing film reduces scrap
The proof-of-concept plant is located in Chassieu in southern France, in a dry room environment at Ingecal, a Dürr Group company specializing in calender technology. Calenders are machines with rollers that compress materials into an even layer. Dry coating starts with film formation: A horizontal calender forms the dry powder into a film. It is referred to as “free-standing” because it runs through the machine without a carrier foil. In the second step, additional calenders compress the film to the desired layer thickness, density, and porosity. Finally, one film is laminated onto the collector foil from each side – thus producing the electrode. “Since we don't need a carrier foil until the final step, we can return the film to the process in its entirety if it does not meet the desired specifications. Thanks to the closed loop, no valuable active material is lost and we significantly reduce waste – an important point in battery production,” explains Bruhn.
Improved further processing
The special characteristic of X.Cellify DC lies in its web guidance: the system transports the free-standing film in a self-supporting manner and compresses the film before it is applied to the current collector. The subsequent lamination onto the current collector requires less force than calendering in the wet coating process, which means that the foil does not deform – improving its processability for the downstream process steps of notching and stacking.
Combined strengths
The new approach to dry coating combines Dürr's expertise in electrode manufacturing and system integration, Dürr Ingecal's high-precision calenders, and LiCAP's patented Activated Dry Electrode® technology. “To take the next step, we are actively seeking pilot partners in the industry for gigawatt-scale projects. This will enable us to bring the technology into real production environments – whether for electric cars, stationary storage or other applications,” says Bernhard Bruhn. Dürr is thus ready to partner in the next generation of battery production – with solutions for wet and dry coating.

Managing the land used to host solar energy projects with conservation practices can be a tool for good land stewardship, offering economic and ecological benefits. The Center for Rural Affairs has released a fact sheet, “Unlocking the Dual Benefits of Solar Energy and Conservation Practices,” that analyzes the dual benefits of solar energy and conservation practices.
Conservation practices are methods used to manage, protect, and restore natural resources, often by minimizing erosion and enhancing biodiversity for long-term ecological health. These practices can be implemented on land being used to host solar projects.
“Solar energy development is often viewed as a threat to various land use practices, but it can actually work alongside them,” said Cora Hoffer, senior policy associate at the Center for Rural Affairs. “Implementing conservation practices on the land under solar panels can improve soil health, and support wildlife and pollinator habitat. It can also offer financial support to farmers and landowners through land-lease revenue or cost savings from on-farm electricity generation.”
Exploring the opportunity to site solar projects on land enrolled in federal conservation programs, like the Conservation Stewardship Program and Environmental Quality Incentives Program, could allow landowners to demonstrate good land stewardship while continuing to generate income.
Several land management practices that can be implemented at solar sites are supported by federal conservation programs, such as grazing livestock to manage vegetation and planting pollinator-friendly species to provide habitat and stabilize soil. Additionally, shade created by solar panels cools the soil and reduces water loss, potentially improving yields and plant quality.
“Rather than viewing solar energy and ecological stewardship as having competing interests, combining them offers a forward-thinking approach to sustainable land-use,” said Hoffer. “It presents an opportunity to address growing energy demand and conservation efforts, while providing financial benefits to farmers and landowners.”
The fact sheet is available in both English and Spanish.
