Solar Optics

Solar Energy Safety Messages You would not ordinarily look directly at the Sun, because it can blind you. Similarly, use caution when concentrating light energy. WHEN EXPERIMENTING WITH SOLAR ENERGY WEAR UV PROTECTIVE SUNGLASSES!! These are not enough protection to ever look directly at the Sun, but they provide some protection in concentrated sunlight. Remember, [...]

Solar Mechanics

Earth spins as it orbits its energy source. Because of the tilt of the daily spinning Earth, and its elliptical orbit as it spirals yearly around the Sun (following the Sun through Space, around the Galaxy), each place on the planet's spherical surface receives differing amounts of energy throughout the day, and throughout the year. [...]

Solar Heat

SOLAR CONSTANT The energy density of solar radiation at Earth's distance from the Sun (150,000,000 kilometers) averages 1361 joules per second per square meter. This is the value of what we call the "solar constant", although though there is some variation due to Earth's elliptical orbit. Consider that the Sun is radiating out energy in [...]

Solar Electricity

Solar Cells - How They Work Solar cells are made of silicon, one of the most abundant elements on Earth (after oxygen and iron). Pure silicon forms tetrahedronal crystal lattices (because of its 4 outer valence electrons). We can stress the electron clouds in crystalline sheets of silicon by adding trace amounts of elements that [...]
