2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Solar water heating (SWH) is heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. [ 1 ][ 2 ]

   Thermosiphon installation have negligible maintenance costs (costs rise if antifreeze and mains power are used for circulation) and in the US reduces a households' operating costs by $6 per person per month. Solar water heating can reduce CO 2 emissions of a family of four by 1 ton/year (if replacing natural gas) or 3 ton/year (if replacing ...

4. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   A solar thermal collector collects heat by absorbing sunlight. 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.

   Worldwide, total installed solar water heating systems meet a portion of the water heating needs of over 70 million households. Heat pumps provide both heating and cooling, and also flatten the electric demand curve and are thus an increasing priority. [162] Renewable thermal energy is also growing rapidly. [163]

   Development in the solar water heating sector progressed steadily throughout the 1990s, and annual growth rates have averaged 20% since 1999. [121] Although generally underestimated, solar water heating and cooling is by far the most widely deployed solar technology with an estimated capacity of 154 GW as of 2007. [121]
