A must-see for those who are thinking, "I'm thinking about installing a solar power generation system in the apartment building I manage, but am worried about the cost..."
If a solar power generation system and storage battery are installed at the same time as V2H as a charging facility or a power source for common areas, part of the costs will be subsidized.

Benefits of the Promotion Project for the Spread of Solar Power Generation Systems for Multifamily Housing
- Self-consumption of the solar power generation system reduces electricity costs for the common areas and each unit
- Although an initial investment is required, maintenance costs after installation are low, so you can expect cost savings in the long term.
- By installing a storage battery, a minimum amount of power can be supplied even during a power outage, providing peace of mind in terms of disaster prevention.
The burden of initial investment can be reduced by taking advantage of subsidies from the national and local governments.
In addition, we will support you with the burdensome application procedures so that you can focus on your core business!

Process to receive subsidy

* If a subsidy application is handled by someone other than an administrative scrivener, it may be in violation of the law.

Reward table
We will inform you of the compensation for supporting your subsidy application, depending on the amount of the subsidy, as follows:
Calculation is based on a step-wise formula (excess progressive).
| Subsidy | Remuneration amount (tax included) |
|---|---|
| Less than 500 million | Subsidy amount x 14% ~ |
| 501 million to less than 1,000 million | Subsidy amount x 8% ~ |
| 1,001 million to less than 3,000 million | Subsidy amount x 4% ~ |
【One case】
In the case of a subsidy of 1,000 million yen
- 500 million yen x 14% = 70 yen
- 500 million yen x 8% = 40 yen
70 + 40 = 1,100,000 yen (tax included)
*Minimum remuneration: 200,000 yen
*Depending on the number and content of your request, we may be able to offer a volume discount from the above amount.
*We will flexibly adjust support content (scope of support) and fees upon consultation.
