| Solar | Solar water heating systems use the sun's energy to heat water. A solar water heating system is made up of several key components including solar collectors, thermal storage, system controls/controller, and back-up, conventional water heater. Sunlight strikes and heats an absorber surface within a solar collector or an actual storage tank. Either a heat-transfer fluid or the actual potable water to be used flows through tubes attached to the absorber and picks up the heat from it (systems with a separate heat-transfer-fluid loop include a heat exchanger that then heats the potable water.) The heated water is stored in a separate preheat tank or a conventional water heater tank until needed. If additional heat is needed, it is provided by electricity or fossil-fuel energy by the conventional water heating system. | View | None |

| Solar Absorptance |
The fraction of incident radiation in the solar spectrum that is absorbed by the material or surface. Value range: 0-1 |

| Solar cover | A solar pool covers utilize the sun's energy to generate heat for the pool. These covers float freely on the pool surface and are designed primarily for heating the pool and prolonging the pool usage season. They are not the most efficient covers for keeping debris out of a pool and are not considered a safety cover. | View | None |
| Solar dish | A solar dish/engine system uses a mirrored dish similar to a very large satellite dish, although to minimize costs, the mirrored dish is usually composed of many smaller flat mirrors formed into a dish shape. The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator. The most common type of heat engine used today in dish/engine systems is the Stirling engine. This system uses the fluid heated by the receiver to move pistons and create mechanical power. The mechanical power is then used to run a generator or alternator to produce electricity. | View | None |

| Solar film | A film that used to reduce solar gain that can be applied to the interior or exterior of a fenestration product. | View | None |
| Solar Heat Gain Coefficient |
The ratio of the solar heat gain entering the space through the fenestration product to the incident solar radiation. Solar heat gain includes directly transmitted solar heat and that portion of the absorbed solar radiation which is then reradiated, conducted, or convected into the space. Legal values: 0-1. |

| Solar parabolic trough | Solar parabolic troughs are a type of linear concentrator system that collects the sun's energy using long rectangular, curved (U-shaped) mirrors where receiver tubes are positioned along the focal line of each parabolic mirror. The mirrors are tilted toward the sun, focusing sunlight on tubes (or receivers) that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. | View | None |
| Solar power tower | A power tower system uses a large field of flat, sun-tracking mirrors known as heliostats to focus and concentrate sunlight onto a receiver on the top of a tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. The energy-storage capability, or thermal storage, allows the system to continue to dispatch electricity during cloudy weather or at night. | View | None |
| Solar Reflectance Index |
A measure of a roof's ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI |

| Solar rings | Solar rings are designed to provide heat for a pool similar to a standard solar pool cover, but are more adept at passing heat to deeper parts of the pool. They can also be turned over when the pool temperature is ideal, enabling them to act as barriers to sunlight that will evaporate water and pool chemicals. | View | None |
| Solar screen | A shading system that is generally made of some type of mesh or woven material, so that a significant amount of solar radiation is blocked. | View | None |
