Re: Solar HWS not approved due to direction in Queensland 15Jul 27, 2017 8:50 am Thanks for that - I will have a look and refer it to the plumber & builder. I did read somewhere though that QLD had removed the option to show a performance solution to meet the requirements but not 100% sure of whether that is true or the implications. Re: Solar HWS not approved due to direction in Queensland 16Jul 27, 2017 10:19 am It is an option for a State to introduce a variation into the NCC to remove or modify part of the NCC. If the option of using a Performance Solution has been removed in this instance, it will be referenced in the PCA. The current NCC 2016 can be downloaded free of charge and you can check this. The installer should have known if this is in fact the case but removing the option to use a Performance Solution goes against the ethos of the NCC and reeks of bureaucratic arrogance and mismanagement. Builders are using more and more Performance Solutions and I have been critical of many that have been surreptitiously introduced to save costs and favour some questionable work practices and difficulty of scrutiny but deleting the option of being able to certify a Performance Solution to allow a solution to a difficult problem while still meeting the performance requirements of the NCC goes against the ethos of the NCC. It is a requirement of the NCC that a Performance Solution be judged on its merits by documented expert assessment, it is bureaucratic incompetence if this has been denied you. Having said that, a State can (I think) still choose not to adopt the PCA in its entirety as was the case until recently with West Australia. I will look through the PCA later today and post what I find. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: Solar HWS not approved due to direction in Queensland 17Jul 27, 2017 12:58 pm I could only see the following in the QLD Appendice on page 131 of the Part 3 (PCA) NCC. If AS/NZS 3500.4 references the 45 degree angle limitation, then it is mandatory which is not in keeping with the NCC's prime purpose to be a performance based document. I don't have AS/NZS 3500.4 unfortunately and buying it would probably cost over $200. The inspector will have it. EDIT 28/12/2018. The linked article below cites the industry disbelief and outrage to this madness. https://reneweconomy.com.au/sudden-biza ... try-13565/ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 3in1 Supadiverta.

Re: Solar HWS not approved due to direction in Queensland 18Aug 01, 2017 9:52 pm The plumbing inspector should stick to what he knows (plumbing) and leave the energy calculations up to those of us who understand solar design and thermodynamics... A solar system in Queensland only loses marginal performance by being outside ideal azimuth and orientation. And west north west is actually probably better for solar hot water because it's heating the water with the afternoon sun for the evening when you use most of your hot water... A little bit of knowledge can be dangerous with some people.
