Section 2:
General guidelines for roof-mounting of the solar collectors.
 The ideal location for the Solar Collectors is on a roof facing the mid-day / early afternoon sun. (North / NNW
in New Zealand).

The panel angle to the sun should be approximately the same as the geographical latitude (e.g. 36° for Auckland,
45° for Dunedin).

If the roof pitch is significantly less than this value, we recommend that the panel is elevated on a frame to
maximise the collector efficiency.
 Clients will have a view on the use of a frame; it is important to explain to them (in writing) that Sunshine Solar
does recommend a frame in these circumstances to maximise efficiency, especially in higher value latitudes
(eg Dunedin).
 It is important also that the panels will not be shaded for any of the day in summer or winter by trees or buildings etc.

 Stainless steel fittings of an appropriate grade must be used, including roof mounting screws.

Roof cladding penetrations must be appropriately sealed according to local building code standards and must
follow good practice at all times.
