b) there are total 40 photovoltic cell
therefore, potential difference = 0.5V
for each cell is
for 40 cell = 40*0.5=20V
thereforethe potential difference for above combination cell is 20V
2.Photovoltic cell for 1cm^2 is 0.5V
therefore for 100cm^2 =100*0.5
=50V
therefore the potential difference is 50V because it incresed by 100cm^2
3. solar energy can be requied during day time and on connecting inverter it stores energy therefore to use the energy at any time at day or night
