Thank you both for taking the time to respond. As you can see though, you have given opposite answers and hence my confusion! @robtm can you please provide a link to where you see that it can only be claimed once per property? The other response from @NCperson links to an IRS page where it says you can claim for each time you install "eligible property," which I would assume additional new panels would be. I am more partial to thinking you can claim each time you add new panels, unless there is some document that states this clearly that it is once only per each property (and you can't claim for additions). Thanks very much.
If you are installing ONE system, you claim the credit one time, when the system is placed in service (inspected, connected, and turned on) regardless of whether the work was spread out and regardless of how long it takes to pay for the system.
If you are installing more than one complete system, you can claim a credit for the first system when it is placed in service, and you can claim a credit for the second system when it is placed in service.
The key is "placed in service." Are you installing two systems that will be placed in service at different times, or one system that will be placed in service at the end of both phases of installation?
