INSTALLATION OF SOLAR COLLECTORS
REGULATIONS AND OCCUPATIONAL HEALTH AND SAFETY (OH&S)

Installation and commissioning must be performed by authorised persons. Rinnai solar systems must be
installed in accordance with these Instructions and all regulatory requirements which exist in your area
including those in relation to manual lifting, working at heights and on roofs. Applicable publications and
regulations may include:
• AS 5601 Gas Installations
•
AS/NZS 3500 National Plumbing and Drainage
•
AS/NZS 3000 Wiring rules
•
Building Codes of Australia
• Local Occupational Health and Safety (OH&S) regulations
• Solar collectors are heavy and bulky items and are usually positioned on the
roofs of buildings. Each Australian State and Territory has a principal
WARNING
Occupational Health and Safety (OH&S) Act which contains requirements
relating to the handling of large, bulky or awkward items and the prevention of
falls from elevated surfaces. Persons installing solar collectors must be aware
of their responsibilities and be adequately trained and qualified, in accordance
with local OH&S requirements.

SYSTEM ORIENTATION AND INCLINATION

The performance of any solar hot water system is determined by the way that the system is installed.
In Australia, the solar collectors should face the equator (North) as shown below. Where this orientation
is not practical, collectors facing within 45 degrees from North (between North-East and North-West) area
acceptable, with a reduction in efficiency of approximately 5%. If the bulk of hot water consumption occurs
before 2 pm face the collectors in a North - Easterly direction. If the bulk of hot water consumption occurs
after 2 pm face the collectors in a North Westerly direction.
The inclination of the solar collectors should ideally be the same as the latitude angle of the site.
Inclinations within 20 degrees of the latitude angle of the site are acceptable, with a reduction in efficiency
of approximately 5%.
