What is the meaning of your question, Were any of these improvements related to the construction of your main home?

I installed solar electric panel on the roof of my main home. This is an 2007 built home. Except the solar panel, I did have any construction. How should I answer you question?

[IreneS]

Answer NO since the solar panel was installed on an existing home and not a newly built home.
