For the uninitiated, a complete lunar eclipse takes place when the Earth comes between the solar and the moon blocking solar’s rays from lighting up the moon whereas a photo voltaic eclipse or surya grahan takes place when the moon passes in a direct line between the earth and the solar and the moon’s shadow travels above the Earth’s floor whereas the solar’s gentle (as seen from earth) is blocked out. In easy phrases, lunar eclipses occur when the moon is close to a node at full moon whereas photo voltaic eclipses happen when it’s close to a node at new moon.
