Solar PV Panel Mounting
26.1
Solar PV Panel Location
For
ease of maintenance
,
short wire issues
and a
reduced chance of lighting strike
- we highly recommend that the
solar panel is mounted
as close to the ground as possible
without running into shading issues.
26.2
Extending the Electrical Wires
The 5meter extension lead can be used to extend any of the three leads, i.e. the 1m pump lead, the 2m over-
temperature lead or the 5m solar lead. Please note, we do not recommend further extensions as this will create too
high a voltage drop. If a further extension is absolutely necessary we recommend you not use the 5m extension lead.
Instead splice in a much higher gauge wire wherever required. You will need to purchase an appropriate splice kit at
your local electrical supplier. If unsure we strongly recommend a qualified electrician splice wires together, as
bad
electrical connections can form a fire hazard.
The solar PV panel acts as a power source AND sun sensor for the thermal OKU collectors.
Hence, the PV panel should be mounted at the same compass direction as the collector
array, with the following exceptions:
1) For West or East facing thermal collector installations it is preferable that the PV panel
face closer to NW or NE respectively.
2) For steep pitch thermal collector arrays it is preferable the PV panel be mounted on a
shallower pitch to get more sun.
