Arch Solar announced the installation of a 191 kW DC solar project on a newly constructed affordable housing and community library complex in Milwaukee, Wisconsin. It is expected that this installation will offset 38% of the total electricity consumption at the location. This project is part of a broader plan in Milwaukee aimed at producing renewable energy on-site for underserved communities. This project provides 93 townhouse style apartments and a newly built public library for a low-income community, supporting long-term affordability by directly reducing residents' utility costs, including allocation of units for rent discounts. The convenience of installation, centralized monitoring, and consistency across multiple sites are key considerations, "said Andrew Holmstrom, Business Development Director at Arch Solar. When you have a unified platform, managing roofs with three different configurations is much simpler. The long string design with a power optimizer reduces our system costs, reduces main cables, conduits, and labor, while providing reliable performance at all locations Arch Solar utilizes a combination of SolarEdge SE50K and SE10K inverters, as well as a dual input power optimizer, resulting in longer strings, fewer home cables, and reduced system balancing (BoS) costs. This setup not only simplifies installation, but also helps the project stay within the strict budget range commonly seen in affordable housing development. Although the ownership model of each building is different, the energy-saving benefits of this system are aimed at directly benefiting residential tenants and community operations, thereby promoting greater economic stability and quality of life. Affordable housing should come with affordable energy, "said Chuck Ellis, Vice President of Commercial and Industrial Sales at SolarEdge. This project demonstrates how smart solar design can produce quantifiable effects where they are most neede.

The Uniform Beauty Act (OBBBA) establishes new rules for which types of solar products are eligible for certain tax credits. The Foreign Entity of Concern (FEOC) rules refuse to provide federal investment tax credits to projects that use too many Chinese components, and prevent US made products that use too many Chinese components from obtaining Section 45X credits. For the solar panel market, this is a complex operation and it is almost impossible to completely avoid using certain Chinese components in the final product. The FEOC rules also refuse to provide tax credits to companies that have Chinese investments or operate under Chinese technology licenses. The market is still waiting for the final explanation from the Ministry of Finance (now expected to be released at some point in 2026), but since HR1 was passed, there has been a wave of clean-up in the supply chain and finance. Companies with manufacturing factories in the United States under the influence of China have been selling or changing business ownership to comply with assumed FEOC requirements. JinkoSolar sells its Dallas solar panel assembly plant to T1 Energy; JA Solar sells its Phoenix solar panel factory to Corning; And Canadian Solar has established a new US division to own its solar panel and battery business related to the US market. Roth Capital Partners stated that multiple contacts in Washington have stated that "the government knows what FEOC is, and if the majority of the business is in China and the intellectual property used is Chinese [or] Chinese companies have effective control, then no matter how many reorganizations, ownership changes, or legal operations are carried out, it is unlikely to be effective. ”

A letter organized by the Solar Industry Association and signed by 143 solar companies has been submitted to the US Senate and House of Representatives in response to a memorandum from the Department of Interior (DOI) that effectively suspended all licenses for solar projects involving the department. Federal agencies are implementing this directive in a manner that almost completely suspends permits for Interior Department involvement in any projects on federal and private land, regardless of their importance, "the letter reads. Businesses need certainty in order to continue investing in much-needed energy projects in the United States. Certainty must include a non discriminatory review process of energy sources. We urge Congress to place fairness and certainty at the center of licensing negotiations The memorandum was released in July and involves federal permits for wind and solar energy projects to be carried out on locations that belong to or are adjacent to federal land or use federal resources. The memorandum states that all "decisions, actions, negotiations, and other initiatives" regarding wind and solar energy facilities must be submitted to the Executive Secretary and the Office of Regulatory Affairs, followed by review by the Office of the Deputy Secretary and final review by the Office of the Secretary, followed by 69 different licensing projects under DOI jurisdiction. For the solar industry in the United States, licensing reform begins with licensing certainty, "said Abigail Ross Hopper, President and CEO of SEIA, in a statement. As 143 solar energy companies wrote in this letter to our congressional leaders, if action is not taken to address unequal treatment of solar energy, the industry will continue to face significant barriers to deployment and investment when energy demand surges. While the solar industry values continued bipartisan cooperation on licensing reform, the SPEED bill, as passed by the committee, fails to address this core issue: ongoing licensing moratoria. ” SEIA released an analysis report in November estimating, based on data from the Energy Information Administration (EIA), that over 500 solar and energy storage projects with a total capacity of 116 gigawatts have been put on hold due to license changes from DOI. To be clear, we certainly need reform permits, "Hopper said. An agreement must be reached, and SEIA and our 1200 member companies will continue our months long efforts to advocate for an agreement that ensures equal treatment for all energy sources, as the current state of lockdown is unsustainable.

The Energy Tool Database and EPC company BPi located in Napa have successfully deployed three Energy Storage Systems (ESS) at Korbel Winery in Sonoma County, California. This installation is part of the winery's broader commitment to sustainable development and the integration of renewable energy into its operations. Energy Toolbase and BPi installed three BYD battery systems integrated with the ETB controller energy management system at the winery. The deployment of advanced energy storage systems aims to reduce demand costs, overcome grid limitations, and optimize energy usage under peak to valley electricity (TOU) billing rates in the region. The project also addressed the 980 kW AC export limit imposed by PG&E due to local substation restrictions, maximizing the use of renewable energy generation on site and achieving significant energy cost savings. BPi implemented a limited export control strategy using SEL-751 relays and inline contactors. Energy Toolbase manages BYD batteries in real-time through an ETB controller with Acumen AI, in compliance with the parameters set by BPi in SEL relays. These controls limit exports to the upper limit defined by the power company and dynamically schedule battery power to minimize peak demand for expensive facilities. Through the dynamic economic scheduling strategy of Acumen AI, the ETB controller optimizes the operation of batteries in real time to determine the most cost-effective scheduling strategy and maximize economic value without human intervention. The ETB controller manages energy flow, peak shaving and valley filling, reduces electricity costs, maximizes on-site energy generation, and provides energy for key equipment such as refrigeration, brewing systems, filling lines, and compressors. Energy Toolbase simplifies the procurement and commissioning process of BPi, ensuring smooth and efficient installation. The project installed 852 kilowatt solar panels on the roofs of four buildings and was equipped with three BYD CHESS devices, each with a capacity of 266 kilowatt hours and a total energy storage capacity of 798 kilowatt hours. This project is a powerful example of how smart software combined with modular energy storage can overcome complex grid limitations and provide immediate, quantifiable value, "said Kevin Muwei, Vice President of Operations at Energy Tools. Our collaboration with BPi has played a crucial role in successfully addressing complex interconnectivity requirements and deploying solutions that have brought significant savings to Korbel

Civ Robotics has launched an artificial intelligence based material distribution system for the solar energy industry. CivNav accelerates solar energy construction by simplifying logistics, efficient pile and pallet placement, and advanced planning and workflow segmentation. We are seeing some very exciting technologies entering the industry to address long-standing inefficiencies, "said Tom Yeshurun, CEO and co-founder of Civ Robotics. For us, the most important factor is to keep it simple and easy to understand, so that everyone on site can benefit from new developments, regardless of their level of experience. As we continue to develop new robot systems, we ensure that innovation and user experience always go hand in hand. To use the CivNav system, the operator installs the sensor box on the machine of their choice and carries the CivNav tablet device onto the vehicle. CivNav is compatible with existing devices, it can be used with any slip steering or telehandler, and has been implemented in Baucat Takeuchi、 On site installation was carried out on Caterpillar and John Deere machines. Once installed, CivNav will guide the operator on how to distribute piles, solar panels, etc. The intuitive interface allows for precise placement with an accuracy of up to 5 centimeters, ensuring that every plan can be executed accurately. When users combine this precise placement with GPS enabled pile drivers, the team can directly skip the layout work. With the increasing use of GPS enabled pile drivers and the expansion of solar projects, eliminating steps like construction layout has become increasingly important. This is another crucial step towards automation in construction sites, which helps bridge the labor gap. Measuring and tracking construction site performance may be difficult, therefore CivNav's artificial intelligence analysis will automatically generate daily reports based on real-time data collected during operation. By providing detailed insights into productivity, output, working hours, travel distance, etc., managers can better identify bottlenecks and continuously optimize workflows as the project progresses. This type of information is crucial for better estimation and driving decisions to measure the success of changes. CivNav collaborates with the company's CivDot+robots to provide a complete autonomous solution for pile drivers with or without GPS. Civ Robotics helped us deploy over 300000 points using CivDots in three different projects, "said Jason Field, BOLDT project executive. When they showed us the CivNav development that eliminates the need for physical point layout in pile distribution, we knew we had to give it a try. After using it for a week, the on-site team praised it endlessly and asked if it could be used for other tasks on other machines

The latest "Electricity Monthly Report" released by the US Energy Information Administration (EIA) shows that solar power generation in September 2025 increased by 29.9% compared to a year ago and provided 9.7% of the country's electricity output in that month, compared to 7.6% in 2024. In the first nine months of 2025, large-scale solar power generation increased by 35.8% compared to the same period in 2024, while small-scale solar power generation increased by 11.2%. The combination of large and small solar power generation has increased by almost one-third (29.0%) and generated slightly over 9% of the total electricity generation in the United States from January to September (large: 6.85%; small: 2.16%), up from 7.2% a year ago. According to the SUN DAY Campaign's review of the data, the situation is as follows. For the third consecutive month, the large-scale solar power generation exceeded the national wind power generation by 4% in July, 15% in August, and 9% in September. Including residential systems, solar energy has consistently surpassed wind energy for five months and increased by over 40% in September. Similarly, so far this year (YTD), solar power generation has easily surpassed the electricity generation of hydropower stations nationwide (accounting for 5.5% of the total electricity generation), and has exceeded nearly 65%. In September alone, solar power generation exceeded twice the power generation of hydropower stations nationwide. In fact, in September and so far this year, solar power generation has exceeded the total power generation of hydropower, biomass, and geothermal. In the first nine months of 2025, wind power combined with large and small solar power provided 18.8% of the total electricity generation in the United States, compared to 17.1% in the first three quarters of 2024. In addition, the combination of wind and solar energy provided 15.1% more electricity than coal and 9.8% more electricity than nuclear power plants nationwide in the first nine months of this year. In fact, with the expansion of solar and wind energy, nuclear power generation has decreased by 0.1%. All renewable energy sources generated 8.7% more electricity between January and September compared to last year, and provided 25.6% of the total electricity generation in the United States compared to last year, instead of 24.2%. Renewable energy generation is now second only to natural gas, and natural gas power generation has actually decreased by 3.8% in the first nine months of 2025. The Trump administration's efforts to revive nuclear energy and fossil fuels have not been successful, "said Ken Bossong, executive director of the Sun Day Movement. The capacity of solar energy, wind energy, and battery storage continues to increase at a significant rate, surpassing natural gas, coal, and nuclear energy, and the gap is constantly widening
