2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A PV solar-powered pump system has three main parts - one or more solar panels, a controller, and a pump.The solar panels make up most (up to 80%) of the system's cost. [citation needed] The size of the PV system is directly dependent on the size of the pump, the amount of water that is required, and the solar irradiance available.

3. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   However, PV-powered active solar thermal systems typically use a 5–30 W PV panel and a small, low power diaphragm pump or centrifugal pump to circulate the water. This reduces the operational carbon and energy footprint.

4. Solar controller - Wikipedia

   en.wikipedia.org/wiki/Solar_controller

   A photovoltaic (PV) powered solar controller uses solar electricity produced on-site to run the pump that delivers the solar-heated transfer fluid to the hot water store. One claimed advantage of PV power is that it reduces the overall carbon emissions associated with operating the system since it avoids the need to supply this energy from ...

5. Solar-assisted heat pump - Wikipedia

   en.wikipedia.org/wiki/Solar-assisted_heat_pump

   A solar-assisted heat pump (SAHP) is a machine that combines a heat pump and thermal solar panels and/or PV solar panels in a single integrated system. [1] Typically these two technologies are used separately (or only placing them in parallel) to produce hot water . [ 2 ]

6. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   The sun’s free energy can also be used to heat water to fulfil domestic hot water demands, such as the hot water that comes out of taps. Solar thermal water heating systems can provide approximately 50% of a property’s annual hot water demand (depending on the size of the property, its location etc) which in turn can help homeowners make ...

   The floating panel can turn contaminated water or polluted seawater into both drinking water and clean, hydrogen fuel. The device works off-grid so could prove useful in places with limited resources.
