  2. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    When a solar water heating and hot-water central heating system are used together, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. However ...

    The inverters, which convert direct current electricity from the solar panels into alternating current used inside the home, are warrantied for 10 years. After that time, Del Chiaro said they can ...

  4. Balance of system - Wikipedia

    en.wikipedia.org/wiki/Balance_of_system

    Cost of balance of system will include the cost of the hardware (and software, if applicable), labor, permitting Interconnection and Inspection (PII) fees, and any other fees that may apply. For large commercial solar systems, the cost of BOS may include the cost of land and building, etc. The cost of BOS can be about two thirds of the total cost.

  5. 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 ...

  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 ...

  7. 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.

  9. 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.
