What Our Customers Say

  • You rock. Thanks for the help.

    Brandon Hoffman
  • Your class saved me both time and money.  I enjoyed the section on commercial sites using batteries with solar to reduce peak demand.  The solar design software parts were also interesting.

    Bill Hennessy, Berks Solar
  • Very informative! Spoke to us directly without reading the slides. However, slides were excellent and merited five to ten minutes discussion each. Very well prepared.

    Electrical Engineer, Lombard IL
  • John puts together one of the industry’s most comprehensive solar design guides.

    Sam Adeyemo, Aurora Solar
  • I really enjoy your courses. Clear and easy to understand, and a great resource of industry info. I especially like that this is up-to-date intel, thanks for sharing the websites too!
