ITC and Schedule E

I assume your setup would qualify as a "solar production facility"

From what I understand, the ITC is a 26 percent tax credit for solar systems on residential (under Section 25D) and commercial (under Section 48) properties. The Section 48 commercial credit can be applied to both customer-sited commercial solar systems and large-scale utility solar farms. 

Since it's commercial rental property it's covered under 26 U.S. Code section 48 which you can read at https://www.law.cornell.edu/uscode/text/26/48

But in a nutshell, yes you can qualify for this credit if conditions are met. So that's why I suggest you read section 48 of the code.  But you may want to read first a more simplistic outline of section 48 at https://www.seia.org/initiatives/solar-investment-tax-credit-itc
