Solar energy and how it is utilized
Inert Solar Systems
Inert solar systems are structural elements of a building which utilize the laws of physics for heat transfer, by connecting solar energy storing it in the farm of heat and distributing it in the area to be heated. The collection of solar energy is based on the greenhouse effect especially the entry of solar radiation through glass or other transparent material and the trapping of heat within the interior of a space. The inert solar systems are often associated with natural lighting techniques for the natural cooling of buildings during summer. They can be applied to new as well as already existing buildings.
Active Solar Systems
The active or solar thermal systems constitute mechanical systems which collect the solar energy, converting it into heat, storing and transferring it by employing some kind of liquid or air as a heat transfer fluid. These systems are used for domestic water heating, for space heating and cooling, for industrial processes, for desalination for a variety of agricultural processes, for water heating of pools etc. the simplest and most common form of an active solar system is well known as solar water heaters (siphons).
Photovoltaic Systems
The photovoltaic systems (P/V) convert the solar energy to electricity thus solving the problem of electrification of areas which are difficult to be supplied from the electrical network (remote houses, lighthouses etc). Small computers and clocks/watches use P/V for their operation. In Cyprus there is scope for the development and application of P/V systems due to the especially high potential of solar energy. Despite this the number of installed P/V systems in Cyprus is very limited.
Within the framework of encouraging energy saving and the use of Renewable Energy Sources (RES), the Committee of the Special Fund for RES and energy saving through the schemes of the Cyprus Institute of Energy of the Ministry of Commerce, Industry and Tourism offers motivation for the purchase and installation of photovoltaic systems with maximum subsidy of 55% on the selected system cost and a maximum amount of subsidy of €64.930 for a maximum subsidised power of 20KW.
