Each cell has a voltage of 18 V Let n be the number of cells in series. So, to produce a voltage of 72 V , LET number of cell required is= N.
So, it is estimated as :Nx 18V = 72 V or N = 72/18=4. So, 4 number of cells are need to be put in series.
Answer:
Explanation:
the power output of a typical photovoltaic solar cell can be calculated as: P = V x I = 0.46 x 3 = 1.38 watts.
this may be okay to power a calculator, small solar charger or garden light, but this 1.38 watts is not really enough power to do any usable work.
The power delivered by the photovoltaic panel to the battery and load connected in parallel with the panel is: P = V x I.
