Why is solar I-V curve tracing important?

[@RedondoBeach2]

I'm impressed by this technician's knowledge. I now live in the Antelope Valley and am aware of the site featured in this video. I drive past it periodically. Would it be possible to contact the technician in the video to get his advice on design recommendations for a new solar system for a home? The home will undergo renovation, to include replacement and redesign of the roof. As the roof is designed and built, I want to optimize it for the ideal solar system for the home, and for periodic cleaning, and testing as appropriate. Perhaps going through this process might make for another great Fluke video. In any case, speaking with the technician would be greatly appreciated if possible. Thanks.
