<pstyle="justify-content: center"><strong> Batteries as electrical storage medium, are very important part of this system because it have to provide the energy when there is no sunlight

So here i have to used sealed lead acid battery.Following are the some calculation for battery size:
Load of Fan= 10W (5W x 2 Nos.) <br>
Running Time (i.e. Backup required) = 6 hour/day <br>
In solar PV system, the DoD( deep discharge) is in the range of 60% to 80%. So here consider 70%.<br>
Therefore the required capacity of battery= 5AH/(0.7 x 100) = 7.14 AH. <br>
In market the battery is availble with capacity 7.5 AH. So I selected this battery. </strong></p>
<h4><strong>c. PV Module</strong></h4>
<pstyle="justify-content: center"><strong> A solar PV module is a collection of solar cells, mainly connected in series. These combinations of solar cells
provide higher power than a single solar cell. The PV module are available in the power rating from 3 watt to 300 watt. They really form the basic building block
of PV system as power generating unit. Here we required a energy from PV module for Battery Charging of around 7.5 AH. The power of battery is used to run a suction fan of

blower. The size of the PV module is decided by the following calculation <br>
Power required for charging in Watt = Battery capacity in AH x Battery Voltage <br>
P in Watt = 7.5 AH x 12 V = 90 WH (Watt-Hour) <br>
Consider the battery charging time is 6 hour/day. So 90 WH/6H= 15 W <br>
So here I selected thep pannel of 15 W or more 20 W depends on availability.
