SolarEnergy Basics

Solar panels installed on a home in Colorado.

Solar is the Latin word for sun—a powerful source of energy that can be used to heat, cool, and light our homes and businesses. That's because more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solarenergy technologies for homes and businesses are solar water heating, passive solar design for space heating and cooling, and solar "Photovoltaic Cell" for electricity.

Businesses and industry also use these technologies to diversify their energy sources, improve efficiency, and save money. SolarEnergy "photovoltaic cell" and concentrating solarpower technologies are also being used by developers and utilities to produce electricity on a massive scale to power cities and small towns.

Concentrating Solar Energy Power 

These technologies harness heat from the sun to provide electricity for large power stations.

Passive SolarEnergy Technology 

These technologies harness heat from the sun to warm our homes and businesses in winter.

SolarEnergy  "Photovoltaic Cell" Technology 

These technologies convert sunlight directly into electricity to power homes and businesses.

Solar Water Heating 

These technologies harness heat from the sun to provide hot water for homes and businesses.

SolarEnergy Process Heat 

These technologies use solar energy to heat or cool commercial and industrial buildings.
