2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Below is a table that gives a rough indication of the specifications and energy that could be expected from a solar water heating system involving some 2 m 2 of absorber area of the collector, demonstrating two evacuated tube and three flat plate solar water heating systems. Certification information or figures calculated from those data are used.

3. Swimming pool - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool

   Use of a pool cover also can help reduce the amount of chemicals (chlorine, etc.) required by the pool. Outdoor pools gain heat from the sun, absorbing 75–85% of the solar energy striking the pool surface. Though a cover decreases the total amount of solar heat absorbed by the pool, the cover eliminates heat loss due to evaporation and ...

4. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.

   Proba-1, an Earth observation satellite, launched in 2001, followed by the sun observing Proba-2 in 2009. Earth-imaging Proba-V (for "vegetation") launched in 2012. Eric Lagatta covers breaking ...

6. Solar pond - Wikipedia

   en.wikipedia.org/wiki/Solar_pond

   When the sun's rays contact the bottom of a shallow pool, they heat the water adjacent to the bottom. When water at the bottom of the pool is heated, it becomes less dense than the cooler water above it, and convection begins. Solar ponds heat water by impeding this convection.
