Eneco Inc. Ranked No. 1 Overall in Tokyo for Recommended Battery Storage Suppliers by MyRefo

Eneco Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Yuma Sawada), a company offering one-stop services across energy, construction, and real estate, is pleased to announce that it has been awarded the No. 1 overall position in the "Top 28 Recommended Battery Storage Suppliers in Tokyo [February 2026 Edition]" ranking published by MyRefo, a guide for selecting trustworthy renovation companies.

■ Behind the Battery Storage Boom: A Surge in "Anxiety Over Choosing a Supplier"

Currently, in addition to historically high electricity prices, a surge in households rushing to install battery storage and solar power systems is being driven by large-scale subsidy programs, such as the Tokyo Metropolitan Government's "Project to Promote the Spread of Disaster-Resilient, Healthy, Insulated, and Solar-Powered Homes," which offers 【up to 4.5 million yen or more】. However, behind this installation boom, consumer troubles related to supplier selection are rampant, including cases of "being pressured into expensive contracts by aggressive door-to-door sales," "water leaks caused by shoddy subcontracted work," and "failing to receive subsidies due to application errors." In response to these industry challenges, a comparative survey by the specialized media outlet MyRefo, known for its strict screening standards, highly evaluated our company as the "most trustworthy supplier (No. 1)" among 28 reputable firms in Tokyo.

■ 3 Reasons Why Customers Who "Absolutely Cannot Afford to Fail" Choose Eneco

The background to our No. 1 selection is our solid system for addressing customer anxieties and comprehensively enhancing the asset value of their homes.

① In-house Construction + "Special Partnership" with a Professional Group Boasting the No. 1 Number of Artisans in the Kanto Region

In the industry, it is not uncommon for construction to be outsourced to different subcontractors after a sale, and then further re-subcontracted to other firms, making construction quality and accountability unclear. At Eneco, while centering on construction and site management by our own skilled staff, we only partner with carefully selected construction companies that meet our strict standards. Furthermore, we have achieved a special partnership with a 【professional group boasting the No. 1 number of artisans in the Kanto region】, a collaboration that is normally difficult to secure. By forming a strong tag team with top-class artisans, we thoroughly eliminate variations in construction quality. We provide high-quality construction that protects your valuable home with a stable and speedy system.

② Zero Complicated Procedures: "Free Subsidy Application Support by Administrative Scriveners" 

While the Tokyo subsidy of up to 4.5 million yen or more is very generous, it requires specialized and complex application procedures. Our company offers "free agency support for subsidy applications" through our affiliated administrative scriveners.

Professionals with a 100% track record in securing subsidies ensure reliable reception, completely eliminating the burden for customers who find the "procedures troublesome" or are "anxious about whether they will actually receive it."

③ Remote Monitoring in Collaboration with Manufacturers and "Lifetime Support" with No Limit on the Number of Calls

Solar power and battery storage are facilities that you will use for a long time, 10 or 20 years. Our company is fully equipped with a maximum 100 million yen construction work warranty for unforeseen troubles and a "lifetime support guarantee" with no limit on the number of calls. Furthermore, we have built a strong partnership with major manufacturers to establish a "remote monitoring system" to check the operational status of the system. This not only allows for early detection of abnormalities but also for your home's
