In other words, is the solar tax credit completely different from the residential clean energy credit. I've read that you can only clean the solar tax credit once (I'm assuming that means a large deduction on a new system), But we may want to add a few panels a few years down the road and our decision would hinge presumably on whether we could claim a deduction for those under the residential clean energy credit instead (which, unlike the solar, appears to be limited to $1,200 in a year)
