Passive (thermosiphon) solar water heaters on a rooftop in Jerusalem. Israel, Cyprus and Greece are the per capita leaders in the use of solar water heating systems supporting 30%–40% of homes. [6] Flat plate solar systems were perfected and used on a large scale in Israel.
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 percent of homes have solar water heating systems. [4]
Solar thermal energy. Roof-mounted close-coupled thermosiphon solar water heater. The first three units of Solnova in the foreground, with the two towers of the PS10 and PS20 solar power stations in the background. Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in ...
By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold. [1] With the 1970s oil crisis, Harry Zvi Tabor developed the prototype of the solar water heater now used in over 90% of Israeli homes. [2] There are over 1.3 million solar water heaters installed as a result of mandatory solar water heating ...
Solar water heaters facing the Sun to maximize gain. Solar hot water systems use sunlight to heat water. In middle geographical latitudes (between 40 degrees north and 40 degrees south), 60 to 70% of the domestic hot water use, with water temperatures up to 60 °C (140 °F), can be provided by solar heating systems.

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.
