Delta Electronics completed a microgrid system at its factory in Detroit, Michigan, developed in collaboration with the local utility company DTE Energy. Unlike traditional power systems, this microgrid is directly interconnected via medium-voltage DTE Energy, enabling Delta to test grid interactive energy strategies under real-time utility conditions and actively support the grid in the future. The microgrid also serves as a validation environment for customers to evaluate grid interactive and microgrid-based power strategies. "Grid resilience is rapidly becoming one of the decisive challenges faced by communities, enterprises, and utility companies. Through our Detroit microgrid, we operate real energy infrastructure under actual grid conditions to understand how the system responds, controls, and contributes to grid stability," said Austin Tseng, President of Delta Electronics Americas. "The system is not an isolated standalone technology but dynamically responds to grid conditions, facility needs, and utility signals. This approach is becoming increasingly critical for data centers and commercial operators in constrained grid environments and rising electricity costs." Delta Air Lines' Detroit plant's on-site microgrid integrates 425 kW of solar power generation, eight Level 2 electric vehicle chargers, and a 400 kW DC fast electric vehicle charger developed under a Department of Energy-funded project. The microgrid connects these assets via a 13.2 kV medium-voltage interconnection provided by DTE Energy—a point on the grid typically reserved for utility-scale infrastructure, completed in April. The microgrid is supported by Delta's 3 MW Power Conditioning System (PCS) and a 2.8 MWh fixed BESS. At the software level, the microgrid's operation is controlled by Delta's Energy Management System (EMS) and monitored by the internal VTScada SCADA platform. The core of this system is the Solid-State Transformer (SST), funded by the U.S. Department of Energy. Unlike traditional passive transformers, the SST employs digitally controlled power conversion to achieve faster grid response, real-time voltage regulation, and more precise coordination across the entire microgrid. This enhances system efficiency and enables more accurate power flow control under dynamic load conditions. These assets collectively reduce the facility's reliance on the grid by approximately 50% annually. During summer, solar power generation should suffice to supply the entire building, achieving net-zero operation. In the remaining six months of the year, energy storage provides load balancing to lower peak demand costs and reduce the facility's electricity expenses. Once fully operational, the device will run daily under real-time grid conditions, helping alleviate pressure on public infrastructure during peak demand periods and generating authentic performance data on how to build and expand commercial energy systems. It provides insights that can assist businesses and data c...

Summit Ridge Energy has completed a 1.62-MW community solar project in Melrose Park, Illinois. The rooftop system was developed in collaboration with with LBA Logistics, a full-service real estate investment and management company, and Black Bear Energy, a commercial buyer’s representative specializing in onsite renewable energy.Hosted on an industrial building owned by LBA, the Melrose Park installation was made possible through the Illinois Shines Adjustable Block Program and participates in the Traditional Community Solar (TCS) program. The rooftop solar project sits within both an Illinois Environmental Justice Community (EJC) and a federally designated Energy Community. Illinois designates EJCs as areas where residents face a disproportionate burden of environmental harm, typically due to a legacy of heavy industrial activity, air and water pollution, and underinvestment in infrastructure. The Illinois Shines program prioritizes such areas, aiming to expand access to clean energy and associated economic benefits. In addition to delivering affordable energy, the project creates local jobs during construction and maintenance, strengthens Illinois’ electric grid through reliable distributed generation, and earns a Rooftop Adder under Illinois Shines, an incentive for utilizing existing rooftop space instead of undeveloped land. “Illinois has become one of the most exciting community solar markets in the country,” said Brent Buchberger, VP of Project Development at Summit Ridge Energy. “The Illinois Shines program is working – bringing affordable, locally generated energy to communities that have historically shouldered the burden of pollution without sharing in solar’s benefits. With LBA and Black Bear Energy as partners who share our long-term commitment, this rooftop project in an Environmental Justice Community is a strong example of what’s possible. We’re proud to see it energized and look forward to many more.” This project represents the latest milestone in a decade-long partnership between LBA and Black Bear Energy that began in 2015. The teams have collaborated on a broad portfolio of community solar projects, including 17.5 MW across four Maryland industrial properties owned by LBA, with the solar systems developed, owned and operated by Summit Ridge Energy under the Maryland Community Solar Program. The program provides locally generated energy at reduced rates to Maryland residents under the Maryland Community Solar Program. Additionally, LBA recently energized two Illinois properties totaling 5.5 MW of community solar, including the 1.62-MW Melrose Park facility. “How we own and operate our assets reflects our responsibility as long-term owners and the value we strive to create in every community where we do business is approached with thoughtful, long-term planning,” said Michelle German, Vice President of Portfolio Operations & Sustainability at LBA. “By hosting community solar on our industrial rooftops, we’re expan...

According to a new white paper from Arizona State University (ASU), the rear-hanging cables in bifacial solar projects do not provide sufficient shading, which can affect the project's performance or reliability. The white paper *Impact of Post Suspension Cable Bundle Sunshading on the Performance Parameters of Bifacial Photovoltaic Modules* was authored by Dr. GovindaSamy Tamizhmani, Director of the Photovoltaic Reliability Laboratory at Arizona State University and Research Professor. Affordable Wire Management (AWM) collaborated in the writing of this paper. "Collaborating with Dr. Mani and the team at Arizona State University on this research has been a true honor," said Dan Smith, AWM's Chief Technology Officer and co-founder. "Arizona State University is my alma mater, making this partnership deeply personal. The research findings we've jointly developed are believed to fundamentally transform the design of bifacial photovoltaic cable management in the entire utility-scale industry." The study found that the number of cables in the rear cable bundle ranges from 2 to 16, with suspension lengths varying from 3 to 6 inches. The impact of cable trays on photovoltaic module performance is negligible, with an effect on Pmax of ≤0.6%, while the 3% to 30% loss associated with installation structures is significantly greater. These results remain consistent across single-axis trackers, fixed tilt systems, and various surface conditions (including white ground), indicating that the evaluated cable tray design is unlikely to cause any meaningful performance loss in practical applications. Beyond performance, industry experience and supplier evaluations indicate that the modular post-cable tray system can significantly enhance efficiency, including reducing total cable length by approximately 20% to 30%, cutting installation time by 15% to 20%, while eliminating pinch points near torque tubes and tracker components. Shadows can be harmful, ultimately leading to reduced energy production, improper power output, and hotspots. The industry is too cautious about this and always arranges cables along structural components such as torque tubes to prevent rear obstruction. However, due to the interaction between wiring and mobile system components, this approach increases cable length and reduces reliability. The research results and white paper prove that shadows are not a factor worth paying attention to, and rear suspension cables do not affect performance and reliability. In addition, a novel metric, Normalized Color Ratio (NSR), was developed and subsequently used to obtain these results. So far, there is no method to quantify the backside shading effect of double-sided photovoltaic devices. NSR isolates the performance impact of cable bundles from other factors, enabling accurate assessment of the actual power generation of the power plant. By establishing standardized methods to measure variables that were previously difficult to calculate, NSR not onl...

Mother's Day is a holiday celebrated to thank mothers, which falls on the second Sunday of May every year. Mother's Day originated in ancient Greece, where on January 8th each year, ancient Greeks paid tribute to Rhea, the mother of the gods. In the mid-17th century, Mother's Day spread to England, and the British designated the fourth Sunday of fasting as Mother's Day. The origin of modern Mother's Day is in the United States. In 1906, Anna Jarvis' mother passed away. On the anniversary of her mother's death the following year, she organized activities to commemorate her mother. In 1907, Anna invited her mothers to hold a worship service. In 1910, Mother's Day was established in Philadelphia. In 1914, the United States Congress officially named the second Sunday of May as Mother's Day, and carnations quickly became a symbol of Mother's Day, representing the tears shed by the Virgin Mary when Jesus was crucified. In the 1920s, Mother's Day was introduced to China. On Mother's Day in 1932, commemorative events were held in the churches of various churches in Shanghai and the Shanghai Youth Association. Subsequently, Guangdong, Jiangsu and other places also began to celebrate Mother's Day. In the 1980s, Mother's Day gradually gained acceptance among the people in mainland China. At the end of the 20th century, with the increasing integration of China and the world, Mother's Day has been increasingly popularized in Chinese Mainland, and people have gradually accepted the concept of Mother's Day. In December 2006, organizations such as the Cultural Committee of the Chinese People's Association designated the second day of the fourth lunar month as Chinese Mother's Day. On Mother's Day, mothers usually receive gifts from their children, such as a bright bouquet of carnations or a delicate bouquet of lilies, as well as other gifts and intentions. Promoting the culture of virtue and filial piety on Mother's Day can not only make families more harmonious, but also make society more harmonious and civilized. Selfless maternal love dedicates everything to her children, and children should promote and inherit the culture of filial piety to maintain family harmony, promote social stability and development, making Mother's Day more meaningful.

ReVision Energy is developing community solar arrays atop the former municipal landfill in Goffstown, New Hampshire. The project is expected to go live early in 2027. Under the agreement, the town of Jaffrey will lease the capped landfill to ReVision Energy for solar panel installation, receiving an annual rental fee of $10,000 and installing escalators over time. "This is the perfect utilization of the land, leaving no room for anything else," said Jon Frederic, the town manager of Jaffrey. "The project creates value for the town while supporting households in greatest need of energy efficiency." The financing for this project was provided by Blue Haven Solar, a solar financing entity under the Blue Haven Initiative. The 1.34 megawatt community solar array is projected to generate over 1.7 million kilowatt-hours of electricity annually. Once operational, 100% of the energy produced by the community solar array will benefit approximately 250 low- and moderate-income households participating in New Hampshire's Electric Assistance Program (EAP). Participants are expected to receive up to $2 million in bill credits over the system's lifecycle. By joining the Low-Income Energy Assistance Program (EAP LMI) Community Solar initiative, participants will achieve a direct savings of 25% on their utility bills for electricity supply. The selection and registration of members will be managed by Eversource, the utility company, and will adhere to the standards set by the New Hampshire Department of Energy. Priority will first be given to EAP customers and waitlisted households within the project's postal code, followed by eligible customers from adjacent postal codes, to help ensure local energy conservation. If demand exceeds the available slots in any priority category, participants will be selected through a random process. "This project demonstrates that when communities, clean energy developers, and mission-driven partners work together, anything is possible," said Mark Zankel, Director of Community Solar at ReVision Energy. "By transforming a capped landfill into clean energy and delivering 100% of the power to households enrolled in the Energy Assistance Program, the Gifford Landfill Community Solar Array will turn an underutilized site into a long-term benefit for the community and Granite Staters in greatest need."
