Solar Energy Basics
CEUs: 0.7 ICC | RESNET: 7 PDUs
Solar energy is one of the few options that a person can use to offset rising conventional heating, cooling, and electricity costs. Basic building science research has shown that adding more insulation, making a residence more air-tight, and installing higher efficiency HVAC* equipment can reduce the cost of the monthly energy bills. Every one of these energy efficiency upgrades can lessen the use of conventional energy but none of them provides an alternative energy source.
Solar energy systems provide energy production independent from traditional energy sources that are based upon fossil fuels or nuclear energy. The potential to disconnect from the electric grid and/or other energy pipelines is highly appealing to many people.
This course represents a comprehensive overview of how solar energy systems, specifically solar electric or Photovoltaic (PV) systems, work. You will learn about the components of solar electric systems, the sizing of solar electric installations and energy storage options. You will also learn the financial aspects of cost/benefit and payback analysis.
*HVAC: Heating, Ventilating, and Air Conditioning (Cooling)

| Module 5 | Connecting to the Grid or Not | |
| A person considering the installation of a solar electric system needs to decide if they want to connect to the electrical grid or not. There are many factors to consider regarding connecting to the grid, including whether to install batteries with the solar system or not. The following units describe the primary configurations for including batteries with the solar installation, which are: Grid-tied solar electric systems without batteries, grid-tied systems that include backup batteries for temporary emergency power or an off grid system containing enough batteries to power a home or small business for a reasonable period of time. | ||

| Module 9 | Sun Path and Solar Window | |
| In order for a solar system to work properly all year there must not be objects that shade some or all of the solar array. The potential for shading that may occur on a solar array at any time of the year can be determined by the "Solar Window", which is the area in the sky that the sun will traverse in over the course of a year. | ||

| It is important to know how large a solar system array or energy output will need to be to match the requirements of the building. A solar system that is too small will likely not produce the energy and monetary savings desired. Too large of a solar system can result in much of the generated energy from the solar system goes to waste or loses value. | ||
