Process to receive subsidy

Emissions businesses contracted by residential solar panel owners who want to take advantage of subsidies;

The owner of the residential solar panel that has been entrusted to the waste disposal company must apply to our company (see the diagram below).

Therefore, subsidies can be used as a sales tool to propose to owners of residential solar panels.

* 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).

SubsidyRemuneration amount (tax included)
Less than 500 millionSubsidy amount x 14% ~
501 million to less than 1,000 millionSubsidy amount x 8% ~
1,001 million to less than 3,000 millionSubsidy amount x 4% ~
3,001 or moreSubsidy amount x 1%~

【One case】

If the subsidy amount is 1,000 million yen, then 70 + 40 = 1,100,000 yen or more (tax included)

  • 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.
