Executive summary
The report discussed about the PV module which is the assembly of the photovoltaic or PV or solar
cells. This has been treated as a vital element of PV systems converting sunlight to DC. On the other
hand, lightning leads to failures in the PV and wind-electric systems. This occurs from lightening
and strikes huge distances from any system or between the clouds. As a result of this, concerns are
rising regarding the afflicting of lightening on the different PV modules. Those modules and its
nearby components get damaged due to this. The study analyzes the effect of lightning on the
various solar panels along with proposing ways to mitigate the lightning effects.

Answer to question number 1:
Solving the given problem:
Given data from the solution:
The voltage in the OV systems = 12 V
Power of the LED= 8 of 10 W
Required to find:
 Number of batteries
 Ah for the 7 days of autonomy
Calculation:
Load = 10 Watts
Required Backup time for batteries = 12 hrs per day = 0.5 days
Now the required Back up Time of batteries in Hours = 0.5 days
Now for One Battery:
8Wh / 10 W = 8/10 hrs
Therefore, 0.5/ (8/10) = 5/10*(10/8)= 0.8
Answer: Therefore for 7 days, number of batteries needed= 0.8*7= 5.6 or 6 batteries
Further for determining the Ah or battery capacity,
Battery Capacity (Ah) = Total Watt-hours per day used by appliances x Days of autonomy (0.85 x
0.6 x nominal battery voltage
8 Wh*6 batteries = 48 Wh
Answer: 48 Wh/ 10 W= 4.8 hours
