Long before modern solar panels, they found ingenious ways to harness solar energy for everyday needs. One of the earliest applications of solar power was for creating fire. Ancient people discovered that by focusing sunlight through polished surfaces or lenses, they could concentrate the sun's rays and ignite flammable materials.
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
Energy from sunlight or other renewable energy is converted to potential energy for storage in devices such as electric batteries or higher-elevation water reservoirs. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available.
Humanity began harnessing solar energy thousands of years ago. Innovations from ancient civilizations to groundbreaking scientific discoveries laid the foundation for modern solar power. Ancient civilizations used sunlight for practical applications.
In the United States, the federal Solar Energy Research Institute (now the National Renewable Energy Laboratory) was created in 1977 to drive innovation in photovoltaics. Germany and Japan also emerged as early leaders in solar technology and manufacturing during this period.
This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy.
