i have a large black walnut tree about 40 to 45' tall and it has two trunks. i'm concern about it falling on house"solar panels". How can i reinforce it to give it structural integrity?

Without a photo, I can't make an accurate assessment. But cabling, or otherwise shoring up the tree, is not generally recommended. Read here:

Trees with two leaders are inherently structurally unsound. They frequently have included bark and are prone to fail. Trees that threaten lives or property are called hazard trees:

You should have your tree assessed by a certified arborist:

It may be easier to remove the tree when it is 40 feet tall than when it is 75 feet tall.
