Subsidy system for fiscal year 7: Overview and subsidy amount

● Solar power generation system subsidy

The amount of solar power generation subsidy for fiscal year 7 remains unchanged from the previous year, as follows:

● Subsidies for battery storage systems

The following revisions were made to storage batteries. The previous subsidy system was designed to provide high subsidies (up to 19 yen/kWh) for small storage battery capacities. For this reason, subsidies tended to be concentrated on households that installed products in a relatively high price range.

In the fiscal year 7 system, the subsidy has been changed to a flat rate of 12 yen/kWh, making it possible for support to be distributed more fairly to a greater number of applicants. The aim is to achieve both optimal budget allocation and efficient energy investment.

Utilize this year's subsidies smoothly with professional support!

The application process requires a lot of paperwork and specialized information, which can be confusing and anxiety-provoking for first-time applicants.
There are also restrictions on the timing of application and contract, and there are cases where people are told they are ineligible because they signed a contract before applying, or they can't prepare the necessary documents in time. However, our company supported over 400 applications to "Cool Net Tokyo" last year alone, and we will fully back up your application with our extensive track record and know-how.
Please leave it to us with confidence.
