You can select a default Custom Component from the drop-down menu on the Custom Library page under the Components Library. Click Custom to see the list of Custom Components. You can view and specify the properties of a Custom Component in the Custom Component Library. You can create a new Custom Component or copy an existing one and change the properties as required. Give the new Custom Component a unique name to distinguish it from the others. HOMER adds the new Component to your library when you click OK. The new Custom Component then appears in the list of available Custom Component types on the Custom Component page under Design. See the Library section of the help for instructions.

There are four types/categories of Custom Components:

1. Renewable Power Source
