The difference here is that when you wire different solar panels in series, you need to use the lowest amp rating of all the panels. Now let’s make the same circuits with three 100 Watt solar panels of 20 Volts and 5 Amps and another 75 Watt panel of 25 Volts and 3 Amps.
#PARALLELS HOME VS PARALLELS PRO SERIAL#
The effect of mixing solar panels in serial and parallel connections But things get complicated when you wire together panels with different voltage and amperage capacities.
#PARALLELS HOME VS PARALLELS PRO SERIES#
So we’ve proved that there is no difference in the power output from a series or a parallel solar system when the voltage and amperage of all solar panels are the same. Total power = 20 Volts x 20 Amps = 400 WattsĮven though the voltage and amperage of our series and parallel solar connections are very different, you can see that the final power output is the same. This is what the voltage, current, and power of our parallel solar panel connection look like. We’ll see why this is important in a little while. We don’t join any of the solar panels together. When we take these same four solar panels and connect them in a parallel circuit, we run the cables from each panel separately into our solar system. Total power = 80 Volts x 5 Amps = 400 Watts How does a parallel solar panel connection work? solar panels wire in parallel We can calculate the voltage current and power of this circuit as follows. The circuit is formed by connecting the positive electrical terminal of one solar panel to the negative terminal of the next in a line and running a cable from each end of this line to the other components of our solar system. We’ll use an example of a series circuit connecting four 100 Watt solar panels. Let’s take a look at how we can connect some solar panels in a series circuit. How does a series solar panel connection work? In a parallel electrical circuit, the voltage stays the same, and the amperage of each component is added together. Looking at the above diagram, you’ll see that in a series of electrical circuits, a battery and two bulbs connect in a single electrical path. Now that I have given you this quick recap let’s move on and look at the difference between series and parallel circuits. Water power = water pressure x rate of flow If you use a hosepipe, the power of the jet is determined by both the water pressure and the speed at which the water is coming out of the hose. Watts = Volts x AmpsĪgain think about the water comparison.
Well, the Watt is the unit that we used to measure the power of an electrical system. It’s a simple way to see how the three main units of electrical measurement are interrelated Instead, if you widen the pipes, then water will flow more slowly.Īnd if you lower the water pressure, then the rate of flow will decrease. If we increase water pressure but don’t change the pipe width, the water will flow more quickly. Now we can see how things change when we alter the system. Rate of water flow = water pressure ÷ pipe width Here’s what happens if we Express this using our water example. Amps = Volts ÷ Ohmsĭon’t worry this little formula is just explaining something quite obvious. Here’s a quick formula explaining how these three units relate to each other. Similarly, if you lower the resistance of an electrical system, you increase its ability to transfer power If you make the water pipes wider, water can flow more easily. It’s harder to push water through a narrow water pipe this is the same as an electrical circuit with high resistance. In the water example, the width of the water pipe represents ohms or the resistance. The ohm is the unit we used to measure electrical resistance. Using our water example, amps represent the rate of flow. In our water pipe analogy, voltage represents the water’s pressure. Voltage is a measure of electrical potential energy. Since electricity flows in the same way as water, imagine an electrical circuit as a series of connected water pipes.
To make things easy to understand, we will use a water analogy. Here’s a quick recap of what each of these terms means. We talk about electricity in terms of volts, amps, ohms, and watts.
Electrons, by the way, are the charge-bearing subatomic particles that give us electrical power. And your home solar setup is also powered by a flow of electrons through a circuit. All the electrical items you use in your home are powered by electrical circuits. I’m going to be talking about electrical circuits, which are simply paths through which electrons flow.
