Learning Objectives

By completing this course, learners will be able to:

  • Reduce the environmental and economic costs of fossil fuel energy and increase self-supply of renewable energy by providing information and resources on proper photovoltaic (PV) operations and maintenance (O&M) so that systems meet project requirements for actual energy delivery;

  • Customize an O&M strategy to achieve renewable energy delivery that corresponds to green building goals by recognizing differences in system size, type, site conditions, and environmental conditions;

  • Ensure staff health and wellness by ensuring that personnel are trained on proper qualifications and personal protective equipment for specific tasks; and

  • Ensure economic savings over the fossil fuel baseline by understanding product warranties, guarantees, and limitations in budgeting for ongoing O&M.
