Solar energy is radiation from the Sun that is capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s energy requirements and could satisfy all future energy needs if suitably harnessed.
People have used the sun's rays (solar radiation) for thousands of years for warmth and for drying food. Over time, we’ve developed technologies to capture solar energy for heat and to convert it into electricity. Radiant energy from the sun has powered life on earth for many millions of years.
Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use. It is a “carbon-free” energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change.

Solar Leaf Chargers and Everyday Solar Tech: How Personal Solar Finally Got Practical
SOLAR is Stony Brook University's enterprise-wide, self-service system which provides faculty, staff, and students with online access to manage personal information. Students use SOLAR to register for classes, print schedules, view and pay bills, update personal contact information, view transcripts, and submit student employment timesheets.
Learn the basics of solar energy technology including solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.
Solar technologies are categorized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on the distance from the Equator.
