The obligation to recycle solar panels has been postponed - JCLP expresses concerns.
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.

Can power generation be achieved even in extreme cold? A demonstration experiment of perovskite solar cells has started in Hokkaido.
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!

Generating electricity on the sea! Mitsui Sumitomo Construction is conducting a demonstration experiment of "floating solar power."
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!

Next-generation solar panels appear on airport roofs.
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.

The future of next-generation energy opened up by perovskite batteries.
~ 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.
