  Solar neutrino physics is an exciting and difficult field of research for
physicists, where astrophysics, elementary particle and nuclear physics meet. \
The Sun produces the energy that life has been using on Earth for many years,
about $10^9$ y, emits a lot of particles: protons, electrons, ions,
electromagnetic quanta... among them neutrinos play an important role allowing
to us to check our knowledge on solar characteristics. The main aim of this
paper is to offer a practical overview of various aspects concerning the solar
neutrino physics: after a short historical excursus, the different detection
techniques and present experimental results and problems are analysed.
Moreover, the status of art of solar modeling, possible solutions to the so
called solar neutrino problem (SNP) and planned detectors are reviewed.
