Solar greenhouse (technical) — A solar greenhouse works by letting in solar radiation to warm the ground, with the structure then trapping the energy to increase and maintain the temperature at a higher level than it otherwise would be. Generally, a greenhouse blocks the heat… … Wikipedia
Solar variation — Solar variations are changes in the amount of solar radiation emitted by the Sun. There are periodic components to these variations, the principal one being the 11 year solar cycle (or sunspot cycle), as well as aperiodic fluctuations. Solar… … Wikipedia
Solar rotation — can vary because the sun is composed of a gaseous plasma, and therefore may lack a fixed rotation rate. The rate of rotation is observed to be fastest at the equator (latitude φ=0 deg), and to decrease as latitude increases. The rotation rate is… … Wikipedia
Solar thermal energy — Solar thermal system for water heating in Santorini, Greece … Wikipedia
Solar energy — is the light and radiant heat from the Sun that powers Earth s climate and weather and sustains life. Since ancient times it has been harnessed for human use through a range of technologies. Solar radiation along with secondary solar resources… … Wikipedia
Solar sail — Solar sails (also called light sails or photon sails, especially when they use light sources other than the Sun) are a proposed form of spacecraft propulsion using large membrane mirrors. Radiation pressure is about 10 5 Pa at Earth s distance… … Wikipedia
Solar hot water — is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. The system may use electricity for pumping the fluid,… … Wikipedia
Solar minimum — is the period of least solar activity in the solar cycle of the sun. During this time, sunspot and solar flare activity diminishes, and often does not occur for days at a time. The date of the minimum is described by a smoothed average over 12… … Wikipedia
Solar maximum — or solar max is the period of greatest solar activity in the solar cycle of the sun. During solar maximum, sunspots appear.Solar maximum is contrasted with solar minimum. Solar maximum is the period when the sun s magnetic field lines are the… … Wikipedia
Solar analog — Solar Type, Solar Analog, and Solar Twin stars are those stars that are particularly similar to the Sun, with solar twin being more similar than solar analog, and solar type being less similar than solar analog. Observations of these stars are… … Wikipedia
