Turning your PV into a
solar hot water system..:
Water heating is one of the largest power
users in a home, together with air conditioners, pool pumps, and refrigeration.
When your premium FiT ends, why not turn
your roof-top array into a solar PV water heating system?
Older technology solar water heating have
collectors on the roof connected by pipe-runs to and from your cylinder, and pump to circulate the
water from the cylinder and back.
Our newest technology solar PV water
heaters don't need to do that: we just take the electricity you generate from the panels and do our
magic, then put this power straight through to your hot water element. Easy.
How does the changeover
We swap out your existing inverter for a
special water heating inverter utilising our unique VOV™ technology.
We also provide you with our HotPV™ hot
water controller which is a smart switch, allowing you to specify when you want hot water every
Our hot water controller is a programmable
device which allows you to say when you want hot water every day - and the controller uses grid
boost to make sure the water is hot when you want it. If you have a different routine every day,
the controller can cope with this as it has a 7 day programming capability.
The easiest way to think of the HotPV™
system is that we are swapping grid electricity for your own solar power, directly to the hot water
The system can be retrofitted to any
existing hot water cylinder with an element.

Don't need "gross" to "net" meter
change - saving the expense..
When we convert your solar PV system to a
solar PV water heating system, it no longer connects to the grid. So metering is no longer required.
And there is no need to change your gross meter to a net meter.
If your power retailer is offering to do
meter swaps for free, great - do it. Some retailers charge several $100 to do a meter swap - you
don't need to do this.
Remember once you convert to a HotPV™ system, your
power company doesn't need to meter how much power you are generating into your
We do recommend you get a smart meter if
your retailer offers to do this at no cost - smart meters can make it very easy for you to monitor
your home power usage. By showing you when power is being used or if there's something using lots
of power, you are armed with the information you need to help you reduce your power bills
