Mr. Takashi's promotion of "perovskite solar cells" - ideals and reality! What should companies choose now?

The ideal and reality of perovskite. What companies should choose now is proven self-consumption solar power generation.

Our company has constructed a total of 83 solar power plants with a cumulative total construction cost of 908.4 billion yen. We take pride in our track record of transactions with companies such as Sharp, Panasonic, Daiwa House, and Mitsubishi HC Capital. Even in high-precision factories and logistics centers, we have achieved up to a 28% reduction in electricity costs and simultaneous CO₂ reduction without stopping operations. 【Industry Challenges】 The rise in electricity prices shows no signs of stopping. The cost recovery for energy-saving equipment installation is unpredictable. There are concerns about power outages and the risk of electricity shortages. 【On-the-Ground Pain Points】 While waiting for "next-generation technology," electricity prices continue to rise. The electricity price in 2025 is about 1.6 times that of ten years ago. Energy-saving equipment alone cannot compensate, and the risk of power outages remains. The gap between companies that wait for "perovskite someday" and those that "build a self-sufficient system with current technology" will directly impact profits in a few years.

Mr. Takashi's warning: "The drawbacks of foreign-made mega solar" - The answer lies in "domestic production × self-generated power."

Total construction cost of 908.4 billion yen, developing and constructing 83 power plants nationwide. Collaborating with major companies such as Sharp, Panasonic, Daiwa House, and JA Mitsui Leasing. Achieving up to 28% reduction in electricity costs, while simultaneously reducing CO₂ emissions and ensuring stable supply. A next-generation "domestic self-generation model" compatible with perovskite solar cells.

Renewable energy is shifting from "quantity" to "quality." The root cause is dependence on imports, and the answer is "domestic production × self-generation."

A next-generation "domestic self-generation model" compatible with perovskite solar cells. 【Industry Issues】 Dependence on foreign-made panels leads to instability in supply and prices. Environmental, landscape, and waste risks associated with the large-scale introduction of renewable energy. From the perspective of energy security, the decline in self-sufficiency rates is becoming serious. 【Current Situation on the Ground】 In factories and logistics warehouses, electricity procurement costs have risen by about 40% over the past five years. The risk of business interruptions during power outages and disasters is also increasing. If we continue to rely on cheap imported renewable energy, the power safety of companies cannot be ensured. Now is the time to establish a system for "producing electricity in-house."

A change in the leading role of renewable energy. The root cause is dependence on imports, and the solution is "domestic production × perovskite."

Total construction cost of 908.4 billion yen, building 83 solar power plants nationwide. Numerous major clients including Sharp, Panasonic, Daiwa House, Nomura Securities, and JA Mitsui Leasing. Achieved up to 28% reduction in electricity costs without stopping high-precision manufacturing and logistics equipment. Simultaneously realized CO₂ reduction. 【Industry Challenges】 Supply risks and price fluctuations due to dependence on overseas panels. Burden of updating aging equipment and the emergence of waste panel issues. Rising electricity prices hinder business continuity planning (BCP). 【On-Site Pain Points】 The structure of "renewable energy = reliance on overseas" threatens the stability of corporate electricity supply. Electricity prices have risen by about 38% over the past five years, and without reducing import dependence, the risks of power outages and price surges cannot be avoided. If the development of domestic technology lags, a future where the renewable energy market is dominated by overseas players awaits.

We will be exhibiting at the only comprehensive and cross-sectional international convention in the marine field in Japan, "Techno-Ocean 2025." In this exhibition, we will introduce a wide range of specialized survey services related to offshore wind power generation projects, including wind and sea condition surveys, O&M, sediment surveys, and fishing ground environmental monitoring. We will also showcase marine surveys and seagrass bed investigations using marine robots such as autonomous surface vehicles (ASVs) and underwater drones, as well as the collection of dead fish in aquaculture operations.

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."

"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.
