- Solar Panel Parallel Connection,
- Solar Panel Series connecteion,
- Solar Panel Series-Parallel Connection
Using a series-parallel connection is necessary sometimes when using soalr panels of different powers and or to reduce the voltage of an solar array vs. connecting in parallel.
Solar Panel Series Connection = Connecting 2 or more panels in a series or connected to one other positive to negative.
Solar Panel Parallel Connection = Connecting solar panels an mc4 branch parallel connector. These are typically available with 2, 3 and 4 parallel connectors..
See picture showing a series parallel connection with a two way MC4 Branch Connector.
This picture shows two sets fo 4 panels connected in a series then connected in parallel with another set of 4 solar panels with a Two Way Branch Connector to create a Series-Parallel Solar array.
-When solar panels are connected in parallel the voltage stays the same.
-When connected in a series, the voltage increases with each panel that is connected.
The same is true with amperage only it is the opposite. So, When connected in parallel the amperage increases with each panel and it stays the same when connected in a series.
