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

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.
