Turbo tax calculated a fed refund that was more than our fed withholdings amount. We installed rooftop solar this year which we are deducting. Is that higher amt ok?

It sounds like you are receiving a Residential Energy Credit which reduces your taxes and increases your refund.  

There may also be other credits on your return which are refundable, such as the Earned Income Credit or the Additional Child Tax Credit, which can generate a refund larger than your withholding.

You can take a look at Page 2 of your Form 1040 to see what items make up your refund.
