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."
