The U.S. Department of Energy works to provide clean, reliable, affordable solar electricity for the nation through its research programs in photovoltaic (PV) energy systems. The following pages explain the "how's" and "why's" of PV. Whether you are a student, builder, consumer, engineer, or researcher, there is something here for you.
Photovoltaic technology makes use of the abundant energy in the sun, and it has little impact on our environment. Photovoltaics can be used in a wide range of products, from small consumer items to large commercial solar electric systems.
Our goal is to ensure that photovoltaic energy systems make an important contribution to the energy needs of our nation and the world. In these pages, you will learn about DOE's R&D in photovoltaic energy systems, and much more. You will also find out—
- How PV works
- Why PV is important
- How and why PV is used
- How DOE is supporting research of solar energy
- How you, the consumer, can use PV and other solar energy technologies
- How builders can incorporate solar into their building plans
- How students, educators, and trainers can learn more about PV
