SUBJECT MATTER EXPERT: William Brooks
Mr. Brooks has worked with
utility-interconnected PV systems since the late 1980’s. He is a consultant to
the PV industry on
a variety of performance, troubleshooting, and training topics. Over the
past 13 years, these training workshops have helped
over 5,000 local inspectors and over 5,000 electricians and
installers understand PV systems and how to properly install
and inspect systems.
His field troubleshooting skills have been valuable in determining where
problems occur to focus training on those issues of
greatest need. Mr. Brooks has written several important technical manuals for
the industry that are now widely used in
California and beyond. His experience includes work on Code Making Panel
4 for the National Electrical Code, Article
690, and IEEE utility interconnection standards for PV systems. He is also
an active participant in Standards Technical
Panels (STP) for UL1741 (Inverters), and UL1703 (PV Modules) and serves as task
group lead for Fire Ratings and
Grounding in UL 1703 STP.
Mr. Brooks holds Bachelor and Master of Science Degrees in Mechanical
Engineering from N.C. State University and is a
Registered Professional Engineer in North Carolina and California.
