Solar energy is a renewable source of energy produced by the sun. Like all energy sources, solar energy has its advantages and disadvantages. A big advantage of solar energy is that it is clean energy. It does not emit carbon dioxide or any of the other greenhouse gases. It does not pollute the environment. Although the initial costs of setting up solar systems are high, they generally pay for themselves in a few years. Moreover, solar energy systems are virtually maintenance-free and can last for decades. The main disadvantage of solar power is the steep initial cost involved in setting up a solar system. Besides, the efficiency of the system relies on the position of the sun and is also influenced by weather conditions and pollution.
