solar panel connection

SOLAR PANEL WIRING

Solar energy system having different type of connection depends on the required output

Series connection of solar panels:

• series connection gives more voltage

 

in series connection voltage is added and current is same

V=V1+V2+V3.....

I=I1=I2=I3......

FOR EXAMPLE:

if panel1=12V,panel2=12V,panel3=12V

output voltage is 12V+12V+12V=36V

Parallel connection of solar panels:

• in parallel connection current is added and voltage is same

I=I1+I2+I3...

V=V1=V2=V3....

Example and connection is shown in the below figure

output current is 4A+4A+4A=12A

 

Series and Parallel connection:

• in some places need both connections .To attain voltage and current efficiently use these type of connections.

 

in this connection both voltage and current added.

V=V1+V2+V3.....

I=I1+I2+I3...

V=12V+12V=24V

I=10A+10A+10A=30A
