Solar energy is one of the best sources of clean power and it is renewable. As an applied physicist in electrical engineering -energy and power systems ,through PV technologies ,it is important to spearhead in researching on the best technology for solar power energy which can contribute in the sustainable energy both in mining and domestic .While photovoltaic technology contributes to clean however, its efficiency and intermittences can undermines the production of mining products such as copper in smelters and induction furnaces which may demand high voltage with stable frequency.The questions which demands answera are

(1) How we make PV technologies more efficient so as to meet the voltage demands in the mines?
(2) How can we stabilize the frequency in the micro grids as well as in the main grids supplying mining industry?
