Abstract:
Solar energy is the most important source of renewable energy, hover the exploitation of
solar energy in Algeria is a major focus of research who knows a great development over the past
decade. Currently there are two main ways to exploit solar energy; solar photovoltaic energy
radiation that turned directly into electricity, solar thermal, which directly converts radiation into
heat. The largest and most expensive components of a solar system are a solar energy complex, a
device that captures solar energy and turning it into useful energy.
The work presented in this thesis is the study and improve the performance of some solar
collectors, many of the technical innovations to improve the efficiency of thermal or hybrid
complexes (PVT) such as; reduce heat loss through the use of tubes transparent "vicious", and
improve heat exchange by adding fins, as well solar as reflectors on the solar collectors are also
allowed to get a good performance of the solar collector. We did do a numerical simulation of
solar collectors, has also been conducting process tests on the model compound and hybrid solar
thermal (PVT) at the research unit for renewable energy in Ghardaia.
