Client Testimonials

Southwest Solar: President and CTO


Proof Engineering has been our best choice for economical design of structures and mechanisms for our solar research and development activities.  They provide us with a unique combination of mechanical and structural design and analysis with fabrication and parts sourcing experience, and the ability to document and PE stamp for third party review.  I think the service from Proof Engineering is much more economical than us doing this work internally, or using a larger firm with higher internal costs.
