(i) It is not possible to make use of solar cells to melt all our energy needs because.
(ii) Limited availability of special grade semi conducting materials such as silicon and germanium.
(iii) Solar cell have lower efficiency as they depend entirely on intensity of solar radiation.
(iv) The process of manufacturing of solar cells is very expensive silver used for inter connection of cell in the panel further add to the cost.
Uses of solar cell:
(i) They provide electric power to satellites and space probes.
(ii) They provide electric power to offshore drilling plants from light houses.
(iii) The T.V relay stations located in remate area use solar panels to get electric power for wireless transmission.
