====Advantages of Solar Cells====
*Can provide power in places not connected to the national grid.
*Do not produce pollution.
*The running cost is almost nothing.
*No fuel cost.
====Disadvantages of Solar Cells====
*Expensive to build.
*Large areas must be covered in cells in order to produce enough electrical power.
*Only work when it’s sunny (not during the night time and slightly less in cloudy weather).
*Cannot increase power output when more is needed.
