Solar energy is radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic etc.
Artificial satellites and space probes like Mars orbiters use solar cells as the main source of energy.
They have no moving parts, require little maintenance and work quite satisfactorily without the use of any focusing device
Silicon, which is used for making solar cells, is abundant in nature but availability of the special grade silicon for making solar cells is limited.
The entire process of manufacture is still very expensive, silver used for interconnection of the cells in the panel further adds to the cost
