Syllabus: (PV 451-452) Energy Storage Fundamentals-Designing Solar Plus Storage Systems
Prerequisites:
Basic Photovoltaics (PV 101)
Course Description
In the first eight-hour day of training, we use presentations, exercises, activities, and classroom discussion to layout the fundamental components and aspects of energy storage systems (ESS) and solar plus storage (SPS) systems. Participants will explore the different aspects of varying forms of energy storage: the history of energy storage; the differing reasons behind the decision to incorporate energy storage; the motivations behind why one would choose to add solar to an ESS; the difference between stand alone versus utility-interactive SPS systems; defining and differentiating between DC and AC coupled SPS systems; outline different configurations and varieties of energy storage technologies. Participants will also begin to look at the factors that go into designing loads (electrical consumption) that will be chosen to be backed up by the SPS system.
In the second eight-hour day of training we use presentations, exercises, activities, and classroom discussion to walk through the design process of solar plus storage (S+S) systems – with an emphasis on lithium technologies. Participants will review design principles for S+S systems, beginning with an overview of the design process and the numerous desired outcomes that can steer S+S design. Along with an analysis of daily loads and determining which loads will be backed up, numerous design variables will be explored in the sizing of the S+S system. This includes the energy and power capability of the battery bank, inverter sizing, array sizing, and various system configurations. While calculating this manually, we will review common design tools from individual manufacturers. As part of the system design, participants will become familiar with energy storage system (ESS) location requirements and all codes applicable to S+S installations. There will be a heavy emphasis on safety regarding all aspects of S+S systems. Participants will also gain an understanding of the necessary steps in the permitting process and have an introduction to available options of manufacturer specific training.
