In this module, we’ll explore the essential element of any photovoltaic system: the solar cell. We’ll examine all aspects of the solar cell, moving from the single cell to a collection of cells that allow us to harness the sun’s power.

The charge controller is a key element of any simple photovoltaic system. This device helps you avoid over or under charging your battery or battery bank. In this module, we’ll focus on both charge controllers and inverters and their important role in photovoltaic systems.

In this module, we’ll start thinking about how to design a simple photovoltaic system. We’ll examine efficiency and develop strategies for determining the right components to meet our energy needs.

Humans have been harnessing the wind’s power for centuries. We’ve used it to help us sail ships, pump water, and grind gain. In modern times, we’re using wind energy to power our homes. The state of California, a pioneer in wind energy utilization, produces energy from its wind turbine farms in excess of 20 terawatts annually. That’s enough energy to power 3 million households.

In this module, we’ll explore the ways water can generate electricity and discuss the components of low-head hydroelectric systems.
