Flat roof stand

Flat Roof Stand

ET30 stand: $416inc GST

ET20 stand: $266inc GST

There are many roofs that may not be ideal for Solar panels. A flat roof stand can assist in optimising the solar panel to gain its best performance. In some cases this is because there is only a mono pitch south facing roof and sometimes the roof is flat or of a very low pitch. A flat roof stand is nominally set to 45 degrees but can be adjusted easily to lower angles. Sizes for flat roof stands are for a 20 tube system or a 30 tube system
solar-ready-kit

Solar Ready cylinder kit

$676inc GST

A solar ready cylinder accessories kit is generally used in a new build and contains specialist pipe and fittings for adding solar. It includes many parts rated for higher temperatures than standard plumbing gear and takes the running around and guesswork out of getting the right fittings, all at a better price than what you would be able to get for yourself if you did all the running around
retrofit-kit-part-1

Retrofit Solar Kit

$838inc GST

We have figured out a way to attach to almost any cylinder. This retrofit Solar kit will enable your existing cylinder to behave as much as possible like a solar cylinder. In addition to the Solar Ready kit above it also includes the electrical upgrades such as the single pole relay and cover, and the fourway T that we have designed to be able to circulate water flow and return through a single fitting
solenoid-valve-1

Solenoid dump valves

$229inc GST

In parts of the country where there are large sunshine hours, also where there are smaller hot water cylinders and potentially low usage there is a potential for overheating. We have designed the control system in the controllers to recognise when there could be a potential issue and to release heat through this solenoid valve to a safe location. The solenoid valve combined with program has eliminated issues that can be caused with high water temperatures and provides control to the uncontrolled heat source (the sun). When ordering your controller please specify if you would like the solenoid valve prewired into your controller. Otherwise these can be purchased separately.
Tile roof fitting kit

Tile roof fitting kit

Kit for ET20: $350inc GST

Kit for ET30: $400 inc GST

Kit for ET40: $450 inc GST

Tile roofs are brittle and difficult to install to unless you have the right gear. The Tile roof kit inculdes 2 x tile roof flashings for the pipe and tile roof brackets to suit the size of panel.. These Galvanised Steel brackets mean that there need not be roof penetrations for panel fixings

4 way T

$

This valve fits into the cold inlet of your hot water cylinder. The “cold” water that flows to your solar panel comes from the same port. From the solar panel the heated water flows back into the cylinder through a small inner riser pipe. This means that the same water is not always circulating and the tank can heat up evenly while keeping its stratification.
non-retrutn-valve

High Temperature non-return valves

$36

A non-return valve job is to ensure that water flows in a single direction. This is an important step to stop hot water thermosyphoning back up onto the roof at night. We have learnt over many years that a high temperature spring non-return valve is the best solution to this and after testing many option we have settled on one that has been extremely reliable over the last 10 years.
Resettable Thermostats

Resetable Thermostats

$54

As part of the standard in hot water cylinders a thermostat (the thing that controls the water temperature and the element) must have an autocut out if the temperature of the water gets too high. This cutout presumes that your cylinder has failed and that power needs to be cut to the element to save it from over-pressurisation. In most standard cylinders if the cylinder goes too hot this thermal cutout pops the breaker in the thermostat. This is a manual reset which means taking off the cover to the element and pressing with a pen after having an annoying cold however. The Resettable thermostat does this automatically saving you having to go through this hassle and thought process. Solar ready cylinders should have this as standard (but some do not).
Single Pole Relays

Single Pole Relays

$

Essentially this is just a switch between the controller and the element. By putting a relay in the line it protects the controller from the high loads that an element can take (around 15 amps). These come with a cover so they can neatly fit into a hot water cylinder cupboard
