  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. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    The most popular solar heating technology for heating buildings is the building integrated transpired solar air collection system which connects to the building's HVAC equipment. According to Solar Energy Industries Association over 500,000 m 2 (5,000,000 square feet) of these panels are in operation in North America as of 2015.

  4. 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.

  5. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Solar water heating systems are most likely to be cost effective for facilities with water heating systems that are expensive to operate, or with operations such as laundries or kitchens that require large quantities of hot water. Unglazed liquid collectors are commonly used to heat water for swimming pools but can also be applied to large ...

  6. Central solar heating - Wikipedia

    en.wikipedia.org/wiki/Central_solar_heating

    Central solar heating is a sub-class of 'large-scale solar heating' systems - a term applied to systems with solar collector areas greater than 500 m 2. Aquifers, boreholes and artificial ponds (costing €30/m 3 ) are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ...
