Solar energy is free therefore it requires no fuel and produces no waste or pollution. In sunny countries, solar power can be used where there is no easy way to get electricity to a remote place.
Solar power doesn't work at night although installing a battery into the solar cells can store energy for the use at night, its also very expensive to build solar power stations and the solar cells cost a large deal of money compared to the amount of electricity they'll produce in their lifetime.
Solar power can be unreliable unless you're in a very sunny climate. In the United Kingdom for example, solar power isn't much use except for low-power applications, as you need a very large area of solar panels to get a decent amount of power.
Solar power could be an answer but technology has to become more advance in order to utilize the sun's power but at the current time it is not very reliable.
