Solar eclipses occur when the Moon's shadow falls on Earth, blocking the Sun's light. Lunar eclipses occur when Earth's shadow falls on the Moon. The reason there isn't one of each every month is due to the specific alignment of the Earth, Moon, and Sun, which must be in a straight line for an eclipse to occur.
Because when the moon passes behind earth, it's usually slightly below or above the path of light from the sun to earth. This allows it to get fully lit from the sun. A lunar eclipse only happens when it passes right through the plane of the sun and the earth, with the earth in between.
To have either a solar eclipse or a lunar eclipse, the sun, earth and moon must be oriented in a straight line. However, the moon revolves around the earth in an orbit which is tilted, so it is not always lined up correctly when it passes between the sun and earth, or when it is on the far side of the earth in the case of a lunar eclipse; e.g., most of the time when the moon is closest to the sun in its orbit around the earth, it is 'above' or 'below' the earth.
The Moon's orbital path, is not perfectly circular around the Earth and more importantly the plane of the orbit does not coincide with the Earths orbit around the Sun. The Moon's orbit is at a slight tilt (about 5 degrees to the plane of the Equator) around the Earth which causes the Moon to be 'above' or 'below' the line between the Earth and the Sun. If the Moon's orbit was not at a tilt and if the axis of the Earth were not tilted, there would be a lunar eclipse every month at full moon and a solar eclipse on the equator every new Moon.
In order for a solar or lunar eclipse to happen the positions of the sun, earth, and moon must be in a specific order.
They do not align in this very often a solar & lunar eclipse can't happen every month
Hopes it helps :)
Edit : The reason is that the plane of the Moon's orbit is tilted at over 5 degrees
to the Earth's orbit.
Lunar (and solar) eclipses do not occur every month because the plane of the Moon's orbit around the Earth is tilted 5.14 degrees with respect to the plane of the Earth's orbit around the Sun. Eclipses only occur when the Sun, Earth, and Moon are lined up in a straight line, and that does not occur every month.
Because Earth's orbit around the Sun and Moon's orbit around Earth are tilted 5 degrees, so sometimes Moon passes below or over Earth's shadow.
We don't get a lunar eclipse (earth obscuring the sun to the moon) or a solar eclipse (moon obscuring the sun to earth) every month, since the alignment of the sun, moon and Earth is not exact enough. The moon sun and earth are not on the exact same plane, so most of the time when the moon passes in front of the sun, it is either too low or too high to cause a solar eclipse. The new moon passes `below` the sun or 'above' it rather than directly in front of it. Its a similar story with a lunar eclipse, there is a higher chance of a lunar eclipse as the earth is larger than the moon, giving a larger target, but even with this in mind, the earth seen from the moon will either pass below the moon or above it most of the time.
The earth moves around the sun in a very slow orbit that takes just over 365 days. The moon orbits the earth at a different rate of just under 28 days. The repetition rate of alignment when he sun falls between the earth and the moon or the moon falls between the sun and the earth is predictable but not monthly.

How many years apart are the lunar and the solar eclipse?
Lunar and solar eclipses can occur within a few weeks of each other or up to two weeks apart. This is because they are both tied to the cycles of the Moon, but the specific type and timing of each eclipse depend on various factors, resulting in variable separations between lunar and solar eclipses.
What eclipse occurs when the sun moon and earth are align with each other?
Either a solar eclipse or a lunar eclipse, depending on the arrangement of the alignment.
How often do the Lunar Eclipse and Solar Elipse happen?
During the 100 years of the 20th Century, there were 228 solar eclipses and 229 lunar ones. So over the long term, you can figure on equal numbers, at the rate of around 7 of each every 3 years.
What are the key differences between a lunar eclipse and a solar eclipse?
A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. A solar eclipse happens when the Moon passes between the Sun and the Earth, blocking the Sun's light.
When is there another eclipse?
On July 1 two weeks after the lunar eclipse) a partial solar eclipse will just touch Antarctica- (would be great to be on the snowfield and see a total eclipse!)On November 25 another partial solar eclipse in the southern hemisphere from the south pacific around Antarctica to the Indian Ocean.A total lunar eclipse will occur two weeks later on Dec. 10 It will be shorter than the June eclipse and from anywhere where there is night at 14:00 Universal Time. the Moon is directly over Guam at the moment of greatest eclipse. Each year there are most often two to four solar eclipses and lunar eclipses.see the site in the Related links and sources below for more information.

Were there any eclipses in the year 1999?
There are, on average, two solar eclipses and two lunar eclipses each year. In 1999, there was an annular solar eclipse on February 16, and a total solar eclipse on August 11. For lunar eclipses, there was a penumbral lunar eclipse on January 21 and a partial lunar eclipse on July 16. You can look up all eclipses from 2000 BC to 3000 AD on the NASA Eclipse web page.
Why are total solar eclipse a rare phenomenon?
On average there are as many solar eclipses as there are lunar ones. But each lunar eclipse can be seen from half the Earth, while a solar eclipse can only be seen from a relatively small strip of the Earth's surface. So in any one place it seems that solar eclipses are rare.
What causes each solar eclipse to occur?
During a solar eclipse, the shadow of the Moon falls on the Earth and blocks out the Sun for a few minutes. There are generally two solar eclipses and two lunar eclipses each year, depending on the...
How often can you expect to see an eclipse?
There are generally two solar eclipses and two lunar eclipses each year. A lunar eclipse happens when the shadow of the Earth falls on the Moon. Each lunar eclipse is visible from the entire night half of the Earth, so on average you will see one lunar eclipse per year, from wherever on Earth that you live. There are also two total solar eclipses per year, but the shadow of the Moon on the Earth is much smaller. So the average person will hardly ever see a solar eclipse, unless you travel to the place where the eclipse will happen. On average, you can expect a solar eclipse to happen where you live once every 58 years. If you would like to see when the next solar eclipse will happen where you live, the link below to the Solar Eclipse Calendar will be useful. To see all solar eclipses in the world, the "World Solar Eclipse" link will give you a map.
Why is the lunar eclipse more frequent than the solar eclipse?
It's not. During the 100 years from 1901 to 2000, there were 228 solar eclipsesand 229 lunar ones ... an average of about 2.3 of each every year.If you stay in one place, though, you see lunar eclipses more frequently. That'sbecause a solar eclipse, when it happens, is visible from only a small area on earth,whereas a lunar eclipse is visible from the entire night-time half of the earth.
Are there more solar eclipses or lunar eclipses?
There are more lunar eclipses than solar eclipses because a lunar eclipse can be seen from any location on the night side of Earth, whereas a solar eclipse is only visible from a limited area on Earth.
How many months between each lunar eclipse?
Lunar eclipses are usually either one month apart or five months apart.
Is lunar eclipse is more frequent than a solar eclipse?
No. during the 100 years from 1901 to 2000, there were 228 solar eclipses and 229 lunar ones ... an average of about 2.3 of each every year. If you stay in one place, though, you see lunar eclipses more frequently. That's because a solar eclipse is visible from only a small area on earth, whereas a lunar eclipse is visible from wherever the moon is visible ... the entire night-time half of the earth.
What is more common solar eclipse or moon eclipse?
Over a long period of time, there are exactly the same number of each. But if you stay in one place, you'll see more lunar eclipses than solar ones, because a lunar eclipse, when it happens, is visible over a much wider area.
What are the two main types of eclipses?
There are eclipses of the sun (solar), and eclipses of the moon (lunar). At different places on the Earth, each of those may be total or partial. Sometimes only a partial eclipse is visible anywhere.
