3.1 System concepts
DAIKIN solar systems are usually set up according to one of the following system layouts.
3.1.1 Parallel connection
3.1.2 Serial connection
As an alternative to the straightforward parallel connection, as described, the solar panels can, if required, also be mounted in a
maximum of three rows one above the other. Solar panels or solar panel fields mounted one above the other must be connected
in series (Fig 3-3). One pack of serial connectors for the selected solar system will be required for each additional row of solar
panels.
