It is a renewable resource
We do not have to worry about the sun ever going away (after all, if it did, we would be dead). Although it may disappear behind a few clouds for a few minutes, disappear completely at night, or for hours during the winter, we can always expect it to come back in full force.
Solar power is non-polluting
Unlike oil, solar power does not emit any greenhouse gases or carcinogens into the air. Solar power is good for the environment (at least, it certainly is not harmful like other sources of power!)
The light and energy from the sun is free. In other words, once you have your solar lights or solar panels set up, etc., you are not going to have to pay to run them.
Solar cells require very little maintenance, greatly because there are no moving parts that must be maintained.
Solar cells can last a lifetime
Solar power is silent powered. The methods used to find and extract oil can be very noisy. Even wind power can create a lot of noise. Solar power, on the other hand, is completely silent.
There are so many advantages of solar power that it is amazing that it is not yet more common. Perhaps the main reason for this is that at the onset, solar power can be expensive. Solar cells are not cheap. Of course, technology for this is improving, and it will continue to improve as the cost of other forms of power increase.
