The statement made by Ms. Sanae Takaichi regarding the promotion of perovskite solar cells is generating buzz. Indeed, perovskite is lightweight and is attracting attention as a next-generation material, but practical application is still a way off. There are several hurdles remaining before commercialization, including mass production costs, durability, and power generation efficiency. On the other hand, the high electricity prices and the demand for carbon neutrality cannot wait. Companies that are "actually operating now" are opting for self-consumption rooftop solar power generation. Ground-mounted mega-solar projects face headwinds due to landscape and environmental regulations, but utilizing the roofs of factories, warehouses, and stores comes with substantial subsidies. Existing high-efficiency panels (especially those from Chinese Tier 1 manufacturers) boast power generation efficiencies exceeding 22% and a 25-year output guarantee, with a level of technological maturity that is unmatched. Rather than chasing dreams of the future, realizing "lower electricity costs now" is the best strategy for corporate management. Now, during the perovskite boom, attention is turning to realistic choices—self-consumption solar power.

Foreign-made solar panels are covering Japan's land." This statement by Sanae Takaichi, the Minister for Economic Security, has caused a stir. As a result of clearing forests and the proliferation of overseas mega-solar projects, landslide disasters, environmental destruction, and issues with discarded panels have emerged in various regions. Furthermore, with the increasing geopolitical risks of the manufacturing countries, "cheap renewable energy" is now being said to pose a security threat. Takaichi has explicitly stated that "renewable energy should be promoted using domestic technology," emphasizing the idea of nurturing perovskite solar cells as a "national technology." This marks a clear shift in renewable energy policy from "quantity to quality" and from "foreign-made to domestic." Amidst this trend, self-consumption solar power systems are gaining attention. These systems complete the process from generation to consumption within the company, achieving local production and consumption of energy. Kenneth Energy Development Co., Ltd. is promoting the "domestication of renewable energy" for factories, logistics, and educational facilities, with a track record of 83 installations nationwide and designs compatible with domestic panels. The era of mega-solar is over, and now it is time for "renewable energy that protects the country.

The government's renewable energy policy is reaching a turning point. As Mr. Takai expressed concern that "foreign-made panels will cover Japan's land," energy "security" is entering a new phase. Relying heavily on the large-scale introduction of overseas panels has led to issues such as forest development and waste disposal. If the review continues to be delayed, it has been pointed out that there is a possibility of over 100 million used panels remaining in the country after 2030. The root cause is "excessive dependence on a low-cost imported electricity structure." To build a truly sustainable renewable energy policy, it is essential to shift to a "locally produced and consumed" energy model. Kenneth Energy Development Co., Ltd.'s self-consumption solar power generation system is committed to domestic equipment, domestic design, and domestic construction, boasting over 8,000 installations nationwide. Companies that have adopted this system have achieved an average reduction of 28% in electricity costs and a significant reduction in CO₂ emissions simultaneously. Now, with the review of renewable energy policies, the ability to generate power in-house is becoming a new competitive advantage for businesses.

"Perovskite solar cells" are once again emerging at the center of Japan's renewable energy policy. Mr. Takai has proposed "nurturing domestic technology for renewable energy" as part of energy and industrial policy, causing related stocks to attract attention in the market as the "Takai trade." The background to this is Japan's long-standing dependence on foreign-made panels in its renewable energy structure. While inexpensive imports have supported proliferation, they have also left a "negative legacy" of forest development, disposal risks, and price fluctuations. If this continues, both the land and energy supply will be controlled by foreign entities—this sense of crisis is the trigger for policy change. Perovskite solar cells possess the trifecta of being lightweight, highly efficient, and low-cost, making installation in existing buildings easy. Development is progressing as a domestic technology, and it is expected to become a mainstay for self-consumption power generation in the future. Kenneth Energy Development Co., Ltd. is developing a "next-generation self-consumption solar power system" with an eye on these perovskite cells. With over 8,000 installations nationwide and expertise in subsidy support, they are turning companies' "energy independence" into reality.

The energy policy promoted by the government has finally made a significant shift from "quantity to quality." The previous large-scale introduction of renewable energy policies relied on inexpensive foreign-made panels, leading to the chaotic installation of mega-solar farms across Japan's land, which created environmental, landscape, and waste issues. As a result, Japan's energy self-sufficiency rate remains at a mere 13%, and even with the advancement of renewable energy, "import dependence" has not been resolved. In light of this reflection, the focus moving forward will be on "developing domestic energy technologies" and promoting "self-consumption type renewable energy." Among these, perovskite solar cells are lightweight, highly efficient, and offer great flexibility in installation, making them a trump card for "decentralized renewable energy" that can be easily retrofitted onto building walls and roofs. Kenneth Energy Development Co., Ltd. is developing a "selective self-consumption solar power generation system" that utilizes domestic panels and perovskite technology. Based on a track record of 83 projects nationwide and a total construction cost of 908.4 billion yen, it supports the industry's "energy independence." Now, renewable energy is entering an era of "security infrastructure."

~ Are lightweight, flexible solar panels becoming mainstream? ~ Film-type perovskite solar cells, organic thin-film solar cells, and lightweight crystalline silicon solar cells are all lightweight and flexible solar panels that stand apart from the traditional "heavy and rigid" panels and are now vying for the spotlight. 〇 Why is "lightweight" gaining attention now? Conventional solar panels are heavy, and due to structural limitations, there have been many cases where they cannot be installed on roofs. This has been particularly true for small to medium-sized factories, warehouses, and hospitals in urban areas, where weight restrictions have become a barrier to installation. This is where the "lightweight and flexible" new panels come into focus. 〇 The key to full-scale development towards 2040: "Perovskite solar cells" The film-type perovskite solar cells are expected to drive future growth. - If you're considering installation, now is the chance! Kenneth Energy Development supports companies in reducing electricity costs and achieving environmental management through industrial rooftop solar power generation.

Mitsubishi HC Capital announced that it will begin a demonstration experiment of perovskite solar cells for cold regions in collaboration with Enecoat Technologies and Hokkaido Electric Power. The experiment will take place in Hokkaido, where the harsh cold can drop to minus 25°C, and will thoroughly examine the durability and power generation performance of the solar cells under such conditions. Starting in August 2025, the performance will be checked by artificially recreating an extreme cold environment in Hokkaido Electric Power's "constant temperature and humidity room." After that, the solar cells will be installed in actual homes to test their power generation performance on windows and exterior walls. The experiment is expected to continue until October 2026. Mitsubishi HC will analyze the economic aspects, Enecoat will handle the manufacturing of the solar cells, and Hokkaido Electric Power will provide facilities and data analysis. By leveraging each company's strengths, they aim to realize solar cells that can be used in snowy regions. Incidentally, YKK AP is also conducting a similar demonstration at the Sapporo Snow Festival, confirming that power generation is possible even with vertical installation, which may accelerate the utilization of renewable energy in snow-covered areas. - If you are considering installation, now is the time! Kenneth Energy Development supports companies in reducing electricity costs and achieving environmental management through industrial rooftop solar power generation.

After the "Logistics 2024 Problem" in 2024, the transportation industry is facing limits in both personnel and operations due to the aging of drivers and labor hour regulations. On the other hand, the electricity consumption of warehouses, distribution centers, and refrigerated facilities is increasing year by year. Electricity prices have risen by about 36% in the past five years, putting pressure on fuel costs, labor costs, and storage costs. -- As the workforce decreases and costs rise, the fundamental cause of this structure lies in the "business model that relies on people and external power." In this context, "self-consumption solar power systems" are gaining attention. By installing them on roofs, garages, and warehouses, companies can generate and consume their own electricity during the day. Furthermore, by combining with storage batteries, stable supply is possible even at night or during power outages. Companies that have implemented this have achieved up to a 28% reduction in electricity costs and a reduction of 96 tons of CO₂ annually. Even with fewer people, solar power can generate income. Self-sufficiency in electricity through renewable energy is the "new workforce" that supports the future of logistics.

A bill to mandate the recycling of solar panels was postponed from being submitted to the National Diet, prompting the environmental economic organization **Japan Climate Leaders Partnership (JCLP)** to publish a statement expressing strong concerns on September 18. The background to this is the expectation that the annual disposal of solar panels will increase to about 500,000 tons starting in the late 2030s. The government had been considering a system to mandate recycling, but difficulties in adjusting the cost burden led to the postponement. JCLP pointed out the need for the early establishment of a flexible and effective system for the effective use of resources, prevention of illegal dumping, and the creation of domestic employment. They stated their commitment to proactively work towards achieving both decarbonization and a circular economy. Additionally, they strongly urged the government to design a system that allows all power generation companies to participate in recycling, stating that there are limits to what can be achieved through the voluntary efforts of businesses alone. Furthermore, Environment Minister Asao announced a policy for reviewing the system at a press conference in August, explaining that consistency with existing recycling laws is a challenge.

Mitsui Sumitomo Construction, in collaboration with Chugoku Electric Power and Chuden Technical Consultant, will work on research for a "floating solar power generation system (floating offshore solar)." This project has been officially adopted as a supported initiative by NEDO, a national research institution. Mitsui Sumitomo Construction, which has built a track record with "floating solar" installations on water surfaces such as reservoirs, is now taking the next step by challenging power generation at sea. This time, they will install panels with an output of approximately 50 kW in the waters off Osaki Kamijima in Hiroshima Prefecture to demonstrate whether they can withstand harsh natural environments such as changes in waves, wind, tide heights, and salt damage. The experiments are set to begin in the latter half of fiscal year 2025 and are expected to continue until the end of fiscal year 2028. They will assess whether safe and stable power generation can be achieved at sea and whether it can eventually become a viable business. The company has already conducted small-scale experiments in Tokyo Bay, and this initiative marks a significant step toward full-scale commercialization. We will continue to pay attention to the new possibilities of solar power expanding from "land" to "sea." - If you are considering installation, now is the chance! Kenneth Energy Development supports companies in reducing electricity costs and achieving environmental management through industrial rooftop solar power generation.

The latest "Calcophyllite Solar Cells" have been installed at the international terminal building of Fukuoka Airport. These solar cells are characterized by their ultra-lightweight and thin design, weighing only 0.8 kg per square meter. Because they can be installed without putting a burden on the roofs of buildings and facilities, they are attracting attention as a technology that greatly expands the possibilities of solar power generation in the future. The installation and demonstration experiments will be conducted by Kyuden Mirai Energy. The solar cells are provided by PXP Corporation, the construction is handled by Kyudenko, and the installation support is provided by JGC Corporation, with performance and construction feasibility being verified from December 2025 to February 2026. Particularly in places like airports, the shape of the roof and the impact of reflected light are also important verification points. This time, practical usability will be confirmed, including those factors. Fukuoka Airport is also planning an exhibition to introduce the details of the experiment. The day may soon come when lightweight and high-performance solar cells become the "norm" in future buildings.

Yanmar Holdings (Osaka City) announced on June 11 that it will start a "farming-type solar power generation (solar sharing)" project that balances agriculture and solar power generation on farmland. The model project will be launched in Shiga Prefecture and Okayama Prefecture from April 2026, aiming to expand to 1,000 hectares nationwide by the fiscal year 2030. This project consists of two models: the "farmer-operated type," where farmers continue their agricultural activities while receiving support funds from Yanmar, and the "in-house farming type," where Yanmar rents farmland and manages everything from farming to sales. The electricity generated from solar power will be supplied to Yanmar Group facilities, with the farm in Shiga Prefecture expected to generate approximately 78,000 kWh annually, reducing CO2 emissions by about 33 tons per year.

The new gymnasium is scheduled to be completed by the fiscal year 2026.

i-Grid Solutions, a company based in Minato, Tokyo, that develops renewable energy businesses, announced on July 9 the launch of a new service called "Circulating Power," which shares electricity for companies that cannot install solar panels. The aim is to achieve both decarbonization and countermeasures against rising electricity costs simultaneously. The service supplies surplus renewable energy generated at solar power facilities operated by the company to facilities where it is difficult to install solar panels due to roof structures or location conditions. This allows companies to adopt renewable energy without the need for installation work, enabling them to start using the service in as little as two months. i-Grid has previously deployed on-site Power Purchase Agreements (PPAs) at 1,226 facilities nationwide, leveraging this experience to circulate surplus electricity within the region. The electricity price is offered at a fixed rate, with options for price fixing for up to 20 years. This is expected to mitigate the risk of fluctuations in electricity prices due to external factors such as rising fuel costs and yen depreciation. According to a survey by the Agency for Natural Resources and Energy, electricity prices for businesses in the fiscal year 2023 have risen by about 1.3 times over the past decade. Japan's energy self-sufficiency rate is approximately 13%, which is low compared to major countries, making stable energy procurement a challenge.

〇Purpose and Method of the Survey Chiba University’s Institute of Environmental Studies and Energy Policy conducts this survey annually (this is the 19th year). Based on renewable energy facilities that are operational by the end of March 2024, we estimate the amount of electricity generation and heat supply if they operate at full capacity for one year. 〇Trends and Key Points Wind Power as a Growth Engine The growth rate has surpassed that of solar power for two consecutive periods, leading the expansion of renewable energy electricity nationwide. Increase in Sustainable Power Zones Slows While the number continues to rise, the growth rate compared to the previous year shows a declining trend. Regional Disparities Become Clear In 24 prefectures, the ratio of renewable energy exceeds 30%. Five prefectures, including Akita, exceed 50%, leading the way. Renewable Heat Hits a Ceiling Due to being outside the FIT framework, it remains a modest increase of +1.4%. 〇What Has Become Clear Over 20% of municipalities have achieved "100% self-sufficiency in electricity": The introduction of renewable energy in rural areas is steadily progressing. Structure Favoring Wind Power: There is significant potential for growth in offshore projects and others in the future. Next Challenges are Heat and Urban Areas: While electricity has grown, improving heat utilization and self-sufficiency rates in densely populated areas is key. Expansion of Municipal Roles: There is a demand for region-led renewable energy plans, grid development, and local production for local consumption models.

Kawasaki Heavy Industries (headquartered in Minato-ku, Tokyo) has begun constructing new experimental equipment at its Kobe factory in Kobe City, Hyogo Prefecture, to "capture carbon dioxide (CO2) from the air." This equipment is scheduled to be completed in October 2025. The aim of this initiative is to efficiently collect not only the exhaust gases emitted from factories and power plants but also the very small amounts of CO2 present in the air around us. If successful, this technology is expected to help reduce CO2, which is a cause of global warming. CO2 Recovery from Factory Emissions At the Kobe factory, in addition to the DAC (Direct Air Capture) system for collecting CO2 from the air, they will also experiment with a method called PCC (Post-Combustion Capture) to capture CO2 from the exhaust of the gas engine power plant located within the factory. This method also applies KCC technology. Expectations for the Future This demonstration facility will be constructed on a larger scale based on experimental results from power plants in Japan and the United States. If successful, it is anticipated that larger facilities and applications around the world will follow in the future. Kawasaki Heavy Industries aims to contribute to the prevention of global warming with this new technology.
