Photovoltaic | Please Help Me With Photovoltaic Systems?

what are two advantages of using it? and what are two disadvantages of using it?

Photovoltaic cells convert light energy falling on them in electrical voltage. Once electrical energy is available you can put it to different uses.Disadvantages are they are still costly and are not economical for large scale application.Most of them are used to harness solar energy and get electricity.So they can be used only when there is Sun light,Batteries can be charged when sun is shining and can be used latter.
