The article presents the main results of solar studies carried out at the Baikal Astrophysical Observatory (BAO) of the Institute of Solar-Terrestrial Physics SB RAS (ISTP SB RAS) for 40 years. It outlines the history of BAO and lists its telescopes. Much attention is given to the Large Solar Vacuum Telescope (LSVT) designed to observe solar formations with high spatial and spectral resolution. Technical parameters of this instrument are specified along with some results of the studies carried out with it. Information about the full-disk chromospheric telescope and scientific problems solved with it is represented together with the basic scientific results. The telescope is used to study solar activity complexes and solar flares. References to the basic publications that have used BAO results are presented.
