Energy Use in the Home
Introduction
Energy from the sun can be tapped to provide a clean source of home energy. This lesson will introduce you to the ways we use energy in the home, and how solar energy can be used to meet some, or all, of a home’s energy needs. It will also address safety, codes and covenants, and permits for Pennsylvania.
Energy Efficiency First
Installing energy-efficient systems in a home is more cost-effective than meeting the energy needs of less-efficient equipment with solar energy. Reducing electricity use is the best and least expensive way to save energy and money.
Using Solar Energy in the Home
Solar energy—energy from the sun—can provide the energy needed for many of these uses. In fact, solar energy can provide all the energy needs in a home. However, systems designed to meet all energy loads in a home are larger and thus expensive.
Zero-energy homes are both energy-efficient and capable of producing enough of their own electricity from solar and other renewable energy resources to offset the amount of energy purchased from the utility. The result is a net-zero annual energy bill.
Advertisement  PV Power Project Training - offered by Institute of Solar Technology This is the Photovoltaic Project Analysis Training Module of Institute of Solar Technology. Here we discuss the operation and application of photovoltaic energy systems, such as the one located on the roof of this research laboratory. This course teaches how photovoltaic (PV) systems operate, how to determine the size of a PV system needed for a certain application, how to install and connect the PV system to the electrical grid.
