yes -
look at Form 1040
https://www.irs.gov/pub/irs-pdf/f1040.pdf
your tax will be presented on Line 16.
the solar credit will be presented on Line 20
Line 20 is subtracted from Line 16, but can not go below zero.
if Line 20 (the solar credit) is greater than Line 16 (the tax), that difference can be carried foward to the following year.
