Randall J. Heckenkemper (born 1958) is an American golf course architect and solar energy entrepreneur.
In 1983, Heckenkemper assisted the partnership of Tom Weiskopf and Jay Morrish, where he participated in several high-profile golf courses including Troon Country Club and TPC Scottsdale in Arizona.
Another of Heckenkemper's courses, McDowell Mountain Golf Club, was the first in Arizona to be awarded Audubon Signature Status.
In 2016, inspired by years of working outdoors and with environmental and landscape construction professionals, Heckenkemper co-founded and is a partner in Site Solar, which designs and manufactures solar-powered, portable light towers and generators.
Site Solar, which has locations and distributors throughout the southwest U.S., specializes in short- and long-term rental of portable, clean, renewable, bright, quiet light through solar power generation, and is especially suitable for the oil & gas industry, construction, public safety, mining, landfills, airports, events, and law enforcement/border patrol.
