    Client Testimonials

    ViaSol Energy Solutions CEO:

    We’ve been working with the principals of Proof since our company was started.  The Proof team performs so well that we have incorporated their mechanical engineering expertise into our own value proposition. After completing five complex solar projects together, and helping us develop two entire product lines, we cannot imagine working with anyone else.
