The maximum number of solar tiles which may be
connected in series depends on the system design,
the type of inverter used and the environmental
conditions.
The number of connections in parallel is determined
by the system design parameters such as the current
or output power.
Long term exposure to wet environments may
cause poor connector connectivity, giving rise to
current leakage and poor conductivity. Tejas Borja
recommends appropriate handling of all cables and
connectors to prevent moisture intrusion. Depending
on the amount of moisture it is exposed to, Tejas Borja
recommends regular inspections of the installation
system to maintain optimum module performance.
The direct current generated by photovoltaic
systems, once converted into alternating current,
may be fed into the public power grid. The policies
of electricity companies regarding the connection
of renewable energy systems to their networks
varies from one country to another. You must
always consult a qualified systems designer or
integrator. Normally, work permits, inspections and
authorizations from relevant bodies are required.
6.9 Connection to the inverter
For safety reasons, please follow the following
instructions and recommendations for the connection
of the
SOLAR FLAT-5XL ceramic roof tile
array to
the inverter.
The inverter must be located as close as possible to
the
SOLAR FLAT-5XL ceramic roof tile
array so
the connection cables can be as short as possible.
All the cabling between the solar tiles and the inverter
must be secured using clamps or cable clips. Always
use corrosion-resistant fixing elements.
The inverter must always be installed in a vertical
position. Check local regulations, the technical
specifications for the inverter and its installation
manual before starting the installation. Always follow
the wiring diagram.
6.10 System wiring diagram
Before beginning the installation, consult the wiring
diagram and check the batten layout is suitable to
hold the array of
SOLAR FLAT-5XL ceramic roof
tiles
, the connections between them and the other
elements in the installation.
A solar installation array made using
SOLAR FLAT-
5XL ceramic roof tiles
will always be formed by
series and parallel connections.
SOLAR FLAT-5XL ceramic roof tiles
include
individual pre-connected wires to connect one tile to
another.
The diagram below shows the recommended cabling
for 93
SOLAR FLAT-5XL ceramic roof tiles
in 3
strings which each contain 31 tiles (the diagram is not
to be scaled up).

Notes: All the tile-to-tile connections and connections to the inverter must be completed by connecting a negative terminal to a positive
terminal, with all the connectors having been designed for this purpose (male – female).
The recommended installation direction is from right to left for strings, and from below to above for parallel
connections. To connect the inverter, use a MC4 cable or equivalent cable of the same length. This cable (bridge)
may be used to check that each row of solar tiles is correctly interconnected, once a complete row has been
installed and before beginning the installation of the row above.
