Reducing Electrical Loads with Photovoltaic Systems
In grid-connected systems, solar energy has the advantage of being available during the times when electricity use is greatest. That means that photovoltaic solar electric systems may be used to reduce your tribe's peak electric loads and, in many parts of the United States, can also contribute to meeting utility peak loads, as depicted in the maps.
Energy produced each year, in kilowatt-hours, for a one-kilowatt photovoltaic solar electric system
Effective load-carrying capacity of a photovoltaic solar electric system, based on comparing solar electric power output with utility electrical load profiles over the course of each day throughout the year.
