Frequently asked questions
Does this page confirm that a specific subsidy or incentive currently exists?
No. This page should not be used as final confirmation of a specific current incentive until the latest policy position has been checked.
Why is manual factual review required?
Because policy, tax, and approval details can create risk if they are out of date or not matched to the real case.
What should a customer do before deciding?
Verify the latest information with the relevant authority or advisor, and ask the installer to define the exact document scope they will manage.
