Why are SOLAR eclipses more rare then lunar eclipses.

Explanation:

Sun oriented shrouds are not really more extraordinary than lunar obscurations – actually, they happen in about equivalent numbers, as a rule around two of each every year. Nonetheless, at any one area on Earth, it is substantially less basic to see a sunlight based overshadowing than a lunar one. Furthermore, the purpose behind this is completely because of math.  

Lunar and sun based obscurations happen with about equivalent recurrence. Lunar obscurations are all the more broadly noticeable in light of the fact that Earth projects a lot bigger shadow on the Moon during a lunar shroud than the Moon projects on Earth during a sun based overshadowing. Accordingly, you are bound to see a lunar overshadowing than a sunlight based shroud.
