home energy credit

My friend has installed solar pannels and financed it.  The principal is 44475.00

She is paying on a monthly instalment 

Does she qualify for home enegy credits?

If I enter the total amount financed of course Turbo Tax show a 7500 credit, but I am not sure if this is correct since she has not paid the full amount yet.  Does she still qualify for this credit?

Thanks my phone is [phone number removed] or email me at [email address removed]

Thank you
