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.
Solar heating is a style of building construction which uses the energy of summer or winter sunshine to provide an economic supply of primary or supplementary heat to a structure. The heat can be used for both space heating (see solar air heat) and water heating (see solar hot water). Solar heating design is divided into two groups:
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.
In 2005, Jamaica embarked on the preparation of a 25-year National Development Plan called "Vision 2030" which encompassed the National Energy Policy 2009–2030. [2] The policy was adopted in late 2009 and followed in 2010 by a National Renewable Energy Policy 2009–2030.
As with photovoltaics, solar water heating attracted renewed attention as a result of the oil crises in the 1970s, but interest subsided in the 1980s due to falling petroleum prices. Development in the solar water heating sector progressed steadily throughout the 1990s, and annual growth rates have averaged 20% since 1999. [121]
