Available Extras

Installing on a tile roof? Ask us to size the number of solar roof hooks required.

Planning on installing rows longer than 12 OKU panels? You'll need expansion joiners to limit the contraction collectors experience overnight.

Installing an odd number of rows? You'll need an add-on panel to finish the array.

Need Wind Category B & C fixings? You can find them here.

Got a skylight you can't cover and need to bridge a row? Buy 4 barbs and two extra joiner sets to create a bridge using 32mm PVC line.

Need an extra non-return valve or 3-way valve? Find them here.

Before you buy

Roof Mounting

Please make sure you have a plan for mounting. Panels are strapped down around their 40mm header pipes to aluminium channels (not supplied) top and bottom using the 6 supplied 316 stainless metal straps. The aluminium channels on metal roofs need to be fixed down by screwing through into battens or rafters. Tile installations are more involved using solar roof hooks that are screwed into rafters and have a protruding external under tile arm/hook that holds the aluminium channels top and bottom of the panels on the roof. See the manual for a full description.

Roof fixing

Wind Loading Considerations

In terms of wind loadings on panels our roof fixing methodology is the highest in its class up to wind region C. See the manual for a full description. We like to take a cautious over-engineered approach to wind loadings and suggest installers do the same as it's very easy to put down more fixings. However, there are some cases where we can't recommend panels over tubes due to high wind loadings (if in doubt please ask). As a guide please note the following recommendations:

Safety Requirements and Product Limitations

  • Warning: Due to the potential of falling from heights, mounting the solar panels on a roof or structure at heights should only be undertaken by a professional solar panel installer, unless you are accustomed to and confident of performing the work safely.
  • For ground level collectors the installer MUST check child safety fence regulations in the relevant state. Under no circumstances should collectors be installed so as to compromise the effectiveness of a child pool or spa fence safety barrier by providing a climbable object.
  • At present this collector array system is not recommended for installations in cyclonic regions C (sheltered only) or D, or on houses situated on top of hills exposed to strong winds, or on second storey (or higher) roofs due to the danger of getting up on these roofs. Installations on tiles are for Wind Region A only.
  • Collectors are to be used with chlorinated (or otherwise treated) pool water ONLY. Do not use collectors to heat fresh (untreated) water due to the potential for Legionella bacteria build up.
  • We recommend collectors be installed with a minimum 2 degree pitch to ensure reliable evacuation of air bubbles.
  • It's not recommended that collectors be installed more than 1m below the waterline of the pool.

FAQs

Sizing and Install Questions

What size system should I use?+

It really depends on your pool's heat loadings, your usage and your budget. For a quick size, use the quick-size calculator on our OKU replacement panels page. Alternatively, for a professional sizing try our full online sizing calculator. If you're not sure what water temperatures your system will produce during various months, use our pool water temperature simulator.

How large are the panels?+

You should budget a gross panel dimension of approx. 140cm in length and 85cm in pipe to pipe width or about 1.2m² per panel.

I was sized a much larger rubber mat system - why is your panel area recommendation smaller?+

Besides the increased efficiency in cooler weather during critical season extension months, we absolutely frown upon the industry practice of selling you a larger system. The Australian Standard 3634-1989 for sheltered pools only recommends 60% (rubber strip) coverage in southern regions, 50% for mid regions, and 40% for northern regions. Over-sizing a system will result in polymer collectors stagnating at detrimental temperatures of up to 80°C for longer periods during hot days when the controller shuts the system down. As such, over-sizing reduces collector lifetimes, requires a larger pump and higher upfront costs - all for diminishing gains in water temperature. If you require higher temperatures beyond our maximum collector recommendation we recommend a solar blanket.

Can I undersize my system and upgrade as needed later?+

Yes, but only to an extent. You should not go below our minimum 2 month extension recommendation, see our interactive sizing calculator. No, we are not trying to sell you a larger system. There are very good reasons why a system should not be dramatically undersized. Effective heating requires a minimum daily turnover, typically 50% of your pool water volume. However, there are flow limitations on panels, hence an undersized system may not handle the flow required which could over-pressurise panels, or if the flow is insufficient will result in an unmixed stratified layer of warm water which will cool excessively overnight.

Can I use a low energy usage variable speed pump?+

No, after witnessing customers try such pumps and struggle with them our advice now is not to use them, unless they can be set to run at a constant speed without a start up surge. We find variable pumps start at full power then taper back, this puts a lot of pressure fluctuations through the panels on start up which could limit panel lifetimes. We only recommend pumps that can pump at a constant set pressure.

I don't have independent solar lines installed on my pool can I tee into my main filter pump suction line?+

Generally we don't recommend this as you may have priming issues with your main filter pump during start up due to air being drawn in from the solar line tee you installed. Whether your filter pump will deprime in this case will depend on how far below the waterline you installed the solar tee. Note, a non-return on the solar line will not help here as non-returns are not generally air tight over time. If you do not have independent solar lines and can't install the tee far below the water line (minimum say 1m below) then your options are a manual system, a booster system or a motorized ball valve option, see the manual for plumbing diagrams.

Is this system easy to install for tiles?+

Installation on tiles is more difficult and we recommend it should only be attempted by experienced DIY or tradespersons.
