1.	Mention why is it not possible to make use of solar cells to meet all our energy needs? State three reasons to support your answer, also mention three uses of solar cell.
Answer» SOLUTION :It is not possible to make use of solar cells to meet all our energy needs because, i) Of limited availability of special grade semiconducting materials such as silicon and GERMANIUM ii) Solar cells have lower efficiency as they depend entirely on intensity of solar radiation. iii) The process of manufacturing of solar cells is very expensive, silver used for inter-connection of cells in the panel further add to the cost, Uses of solar cells : i) They PROVIDE electric power to satellites and space probes ii) They provide electric power to off-shore DRILLING plant formed and light houses iii) T.V RELAY stations are wireless transmission systems located in remote areas use solar panels to get electric power
