Residential energy credits

Signed contract with downpayment 9/9/2024 for large solar array.  Install construction did not start until 2nd week of January 2025.  Invoiced for remaining cost on 1/16/2025 even though there were a few additional construction issues due to bad weather.  Made final payment on 2/19/2025.  Enabled system on 2/22/2025 after power company meter replacement.  Vendor says I can apply for credits in 2024; however, logic says that I should file in 2025.  NY State form requires enable date be entered.  What if with all of the commotion in Washington, could the credit program be cancelled this year?
