What do you picture when you hear the term "renewable energy?" Do you imagine fields of solar panels, giant windmills, or huge hydroelectric dams? Those are all examples of large-scale, grid-tied systems. In this course, we'll go much smaller and focus on off-grid, stand-alone systems. We will explore the key components of photovoltaic, wind, and hydroelectric systems. We will examine photovoltaic, or PV, system components, and the scientific laws essential to understanding how renewable energy systems work. We will discuss wind energy and low-head hydroelectric systems, focusing on small-scale implementations. During our exploration of these systems, we will focus on safety and regulating bodies that guide proper system design. Throughout the course, you will be able to apply what you're learning by conducting an energy audit to analyze power consumption, identifying essential system components of small-scale systems, building a budget for a small-scale system design, and creating a design for implementing a small-scale system.
