Give scientific reason
It is possible to produce energy from mW to MW using solar photovoltaic cells.
Solar photovoltaic cells can be arranged according to the requirement of electric power. If power requirement is within mW, use of few number of photovoltaic cells will be able to achieve this much power. But, if the requirement of power is in MW, then large number of cells are grouped together to form a solar panel. Then, large number of solar panels are connected in series and parallel to get the required electric power. Thus, it is possible to produce energy from mW to MW using solar photovoltaic cells.
