Electrical Learning Part-16||Week-16||Power generation process by connecting solar panels in parallel.

Steemian Friends,
Today, I will write my Solar Electrical Learning Part 16 and Week 16. Last week, I showed how to connect solar panels in series. Today, I will show how to connect solar panels in parallel. I hope you will benefit from reading my article about solar.

I have drawn a diagram of four 20-watt panels connecting the solar panels in parallel. Ten panels instead of four will be connected in the same process. We know that a panel has two terminals. A positive terminal, which I have marked as positive. The other is the negative terminal, which I have marked as negative. I first connected the negative four terminals to the same end. Then, I connected the positive terminals to one end. But I connected one diode to each positive terminal.

Solar panels in parallel Connection

Blocking diodes are used when solar panels are connected in parallel. When multiple solar panels are connected in parallel, a blocking diode is connected to each solar panel. When any one solar panel is isolated from sunlight, blocking diodes prevent the current generated from other solar panels from flowing to that isolated panel.

Bypass diodes are used when solar panels are connected in series, and blocking diodes are used when solar panels are connected in parallel. In this case, the diode acts as a kind of switch. In modern solar systems, diodes are used for switching and filtering.

When solar is connected in parallel, the output voltage remains the same. If I get 12 volts from each panel, then the output voltage will be 12 volts. In this case, even if the output power is increased, the output voltage will remain the same. The reason for connecting solar panels in parallel is to increase the power and keep the voltage the same.

By connecting the above four solar panels in parallel, the output voltage will be
V1=V2=V3=V4= 5 Volt.
Output current will be I1 +I2+I3+I4= 3+3+3+3=12 Amp.
Output Power = Output Voltage * Output Current = 5*12=60 Watts.

We will check the equipment rating before installing the solar panel. Because my equipment rating is 12, 24, 220 and 440 voltage in the market. If our equipment is 220 volts, then I have to calculate the solar panel design so that the output voltage is 220 volts. Then, I need to increase the output voltage by connecting the solar panels in series. Because solar panel voltages add up in series. However, the voltage of the parallel solar panel remains the same. I hope everyone understands my reason for connecting series and parallel solar panels.
