How to connect 2 coleman solar panels.
You ll still need the mc4 to 8mm adapter with a positive mc4 female connector.
Theses are the diodes that i use they are the same ones that are used when building the panels.
Parallel series and a combination of parallel and series.
Maximum rated voltage 19 8v.
There are 3 ways to connect solar panels.
If we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series.
Maximum rated current 5 8a.
Connecting two solar panels in parallel.
This will connect two panels in parallel by connecting the two positive wires together and the two negative wires together.
If both panels are rated at the same maximum voltage then you ll get maximum output.
The parallel connection allows to increase the current keeping the same voltage.
As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.
The positive wires will be separate from the negative.
For example our 115w sunpower solar blanket has the following ratings.
