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 [19] 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 thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   Hot water solar systems require heat exchangers due to contamination possibilities and in the case of unglazed collectors, the pressure difference between the solar working fluid (water) and the load (pressurized cold city water). Large-scale unglazed solar hot water heaters, like the one at the Minoru Aquatic Center in Richmond, BC operate at ...

5. Storage water heater - Wikipedia

   en.wikipedia.org/wiki/Storage_water_heater

   Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal 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.

6. Solar-powered Stirling engine - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_Stirling_engine

   NASA patented a type of solar-powered Stirling engine on August 3, 1976. It used solar energy to pump water from a river, lake, or stream. [1] The purpose of this apparatus is to “provide a low-cost, low-technology pump having particular utility in irrigation systems employed in underdeveloped arid regions of the earth…[using] the basic principles of the Stirling heat engine“.

7. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   Solar stills can be used to make drinking water in areas where clean water is not common. Solar distillation is necessary in these situations to provide people with purified water. Solar energy heats up the water in the still. The water then evaporates and condenses on the bottom of the covering glass. [28]
