This is usually the case with 24v systems.
How to hook solar panels in series.
If you had 4 solar panels in a series and each was rated at 12 volts and 5 amps the entire array would be 48 volts at 5 amps.
In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported.
When installing solar panels in series the voltage adds up but the current stays the same for all of the elements.
By connecting multiple solar panels in series we increase the system voltage.
When you connect two or more solar panels like this it becomes a pv source circuit.
After these clarifications let s see how the series connection takes place.
The capacity of a solar panel to produce energy is measured in watts which is calculated by multiplying a solar panel s voltage by the amps of current it produces when a solar installer builds a solar energy system they need to find the right balance of voltage and amps to ensure that the system performs well.
Firstly lets take a look at connecting solar panels in series.
This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency.
If we connect 4 x 150w solar panels in series the total power is calculated as follows.
Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another.
For example if you installed 5 solar panels in series with each solar panel rated at 12 volts and 5 amps you d still have 5 amps but a full 60 volts.
Total power 150w 150w 150w 150w 600w.
Connect the positive terminal of the first solar panel to the negative terminal of the next one.
Should you connect a 3a solar panel to a 3 5a solar panel the all round current will probably be pulled down to 3a.
When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.
