4. INSTALLATION
XUNZEL PV modules can be installed both in series and in parallel.
Modules can be wired in series to increase voltage. Connect wires from the positive terminal of one module to the negative terminal of the next module.
Illustration 4.1 shows four modules connected in series.
Series Connection for More Voltage Parallel Connection for More Current

Modules can be wired in parallel to increase current. Connect wires from the positive terminal of one module to the positive terminal on the next module.
Illustration 4.2 shows four modules connected in parallel.
Note: it is recommended that all the connections should be performed using watertight junction boxes. An inadecuate connection may affect seriously
the performance of the entire system, even wasting all the energy generated by the PV modules. Keep in mind that the connection should be durable.
AIR CIRCULATION UNDER MODULE
Sufficient clearance between the module frame and the mounting surface is required to allow cooling air to circulate around the back of the module.
This also allows any condensation or moisture to dissipate.
MOUNTING OPTIONS
There are many types of mounting systems used to install Xunzel modules. Modules should be firmly fixed
in place in a manner suitable to withstand all expected loads, including wind and snow loads. Module
mounting holes are provided for easy installation and proper mechanical loading. Do not drill additional
mounting holes in the module frame as it will void the warranty. The use of proper mounting hardware is
recommended to minimize the mounting structure, and hardware possibility of corrosion of the module frame.
Mounting examples: ground mounting, roof installation and on pole mounting.
