advantage
Solar energy is a clean and renewable energy source. Once a solar panel is installed, solar energy can be produced free of charge. Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years. Solar energy causes no pollution.
disadvantage
Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments. Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate. Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build. Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time
