Solar Neutrinos

The Sun is a powerful neutrino source that can be used to study the physical properties of neutrinos and, at the same time, neutrinos are a unique tool to probe the interior of the Sun. For these reasons, solar neutrino physics is both fundamental neutrino and solar physics. In this paper we summarize shortly the main results of the last three decades and then focus on the new results produced by running experiments. We also give a short look at already funded or proposed new projects and at their scientific perspectives.
