2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

3. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   The combination of solar water heating and back-up heat from a wood stove chimney [20] can enable a hot water system to work all year round in cooler climates, without the supplemental heat requirement of a solar water heating system being met with fossil fuels or electricity.

4. Solar pond - Wikipedia

   en.wikipedia.org/wiki/Solar_pond

   Diagram of a solar pond. A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration (and therefore density) with ...

6. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   Increasingly, solar powered water heaters are being used. Their solar collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal. In Cyprus and Israel 90 ...

7. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
