An overview of existing and future solar power stations. A solar collector, the special energy exchanger, converts solar irradiation energy either to the thermal energy of the working fluid in solar thermal applications, or to the electric energy directly in PV (Photovoltaic) applications.
The progress of solar energy conversion technologies during the last few decades triggered the development of various types of collectors, thermal, photovoltaic (PV), or hybrid. In this paper, authors present the basic elements of thermal (energy and exergy) analysis solar collectors and their efficiency.
The rear side insulation was made of 40 mm glass wool; the frame of wood is covered with aluminum sheets. The outside dimensions of the collector are 1389 × 750 × 80 mm with an aperture of 0.92 m 2 and 0.77 m 2 covered with PV cells to avoid shading losses by the frame reducing the electric performance.
The mathematical model of solar collector consists of external energy balance of absorber (heat transfer from absorber surface to ambient environment) and internal energy balance of absorber (heat transfer from absorber surface into heat transfer fluid).
Installation of flat solar collectors (FSCs) has been increasing due to the zero cost of renewable energy. However, the performance of this equipment is limited by the area, the material and the thermophysical properties of the working fluid. To improve the properties of the fluid, metal and metal oxide nanoparticles have mainly been used.
It allows a very detailed specification of collector geometrical and material parameters. It covers a large segment of solar collectors (unglazed, single and double glazed) and evaluates also optical properties of the collector, e.g. incident angle modifier.

3.1 Stationary collectors Solar energy collectors are basically distinguished by their motion—stationary, single-axis tracking, and two-axis tracking—and the operating temperature. First, we''ll examine the stationary solar collectors. These collectors are permanently fixed in position and do not track the sun. Three main types of collectors ...

Solar-thermal collectors are devices that absorb solar energy. These are of either concentrating or non-concentrating type. The collector and absorber area are the same in a non-concentrating type such that the whole panel absorbs solar energy, whereas a concentrating solar collectors have a larger interceptor compared with an absorber.
Various types of solar collectors are reviewed and discussed, including both non-concentrating collectors (low temperature applications) and concentrating collectors (high temperature applications). These are studied in terms of optical optimisation, heat loss reduction, heat recuperation enhancement and different sun-tracking mechanisms.
