The credit is allowed for your main home and secondary/ vacation homes (not a rental property). The credit is used to reduce your tax liability. The credit is 30% of the total. There is not a good way to enter a second home and address. You can enter the full expenses for one address that you select.
For a rental property, enter the solar installation as a depreciable asset in the Rental section or use Form 3468 in Wages & Income > Business Deductions & Credits >Other Business Credits.
