Tim Crane is Senior Director of Supply Chain at Palmetto, where he leads sourcing, planning, and procurement across the company’s hardware portfolio, with direct accountability for approved vendor and product management and compliance with FEOC, UFLPA, and Domestic Content requirements.
Tim brings two decades of solar procurement leadership to the panel, having built and directed sourcing organizations at Sunrun, Tesla/SolarCity, and Mainstream Energy (parent of REC Solar and AEE Solar). Across these roles he has led global hardware sourcing strategy covering modules, inverters, batteries, and mounting systems — consistently delivering material cost reductions while maintaining the service and quality standards that large residential and commercial portfolios demand.
Throughout his career, Tim has operated at the intersection of two competing imperatives that define serious procurement leadership: the relentless pressure to reduce cost of acquisition, and the equally real obligation to ensure that what gets specified and purchased will perform bankably over a 25-year asset life. His work has consistently required reconciling those demands while navigating supply chain traceability, ethical sourcing, and third-party quality assurance — the same issues now at the center of the U.S. manufacturing conversation.

Under Mike’s leadership SEMA has built strong, bipartisan ties in Congress as well as the Administration, becoming a leading voice in continuing manufacturing reshoring efforts.
His federal government experience – spanning the U.S. Department of the Interior, the Senate Energy Committee, and the U.S. Department Energy – has been focused on creating policy incentives and frameworks to enable the U.S. clean energy industry to flourish and deliver its benefits both in affordable energy and quality jobs to Americans.
His most recent federal service was as the Principal Deputy Assistant Secretary for the Office of Energy Efficiency and Renewable Energy and the Senior Advisor to the Director of Energy Policy and Systems Analysis at the US Department of Energy from 2012 to 2015. He was a member of the leadership team advising the Secretary on clean energy policy, in addition to being a guiding force on the R&D and deployment agenda within EERE.
Prior to DOE, Mike served as Senior Counsel to the Senate Committee on Energy and Natural Resources from 2004 to June 2012. In that influential role, he conceived of, drafted, and guided through Congress a number of incentive programs and laws that now direct major Department of Energy programs. Prominent examples include the Advanced Technology Vehicle Manufacturing Program (used by Tesla, Ford, and Nissan to significantly expand US manufacturing of cutting-edge vehicles), and the L-Prize (which helped catalyze the commercial introduction of consumer LED light bulbs). All of these policies enjoyed broad bipartisan support.
He holds a law degree, with a Certificate of Specialization in Environmental and Natural Resources Law, from Lewis and Clark College and a Bachelor’s from the University of Colorado – Boulder.
