Can I take the energy credit for solar panels installed on my 2nd home in 2018 or does it have to be my primary home?

My panels were purchased, not leased.

You can claim the Residential Energy Efficiency Property Credit for solar, wind, and geothermal equipment in both your principal residence and a second home. But fuel-cell equipment qualifies only if installed in your principal residence.
