This complete DIY kit for PV hot water is perfect for technically competent individuals who have a basic understanding of electricity.

The kit comes with 3 high-quality 440Watt PV panels, totaling 1320Watt, that are designed with a sleek black mounting system and L-Brackets for metal roofs. An upgraded kit for tiled or flat roofs is available.

The kit also features a solar MPPT controller for hot water and an AC/DC element.

3 x 440Watt PV panels with a total of 1320Watt

With all of these components, you'll have everything you need to get started with photovoltaic water heating.


For the DIY installation, you will start by replacing the existing element with our special dual-core PTC element. This is done by draining the cylinder, screwing out the old element and screwing in the new. Then 3 x 440-watt photovoltaic (PV) solar panels (clip together) will be provided (22kg each) with a mounting system that goes on the roof, with a single solar cable that goes down to the hot water cylinder. At the cylinder, you will have an MPPT controller and then into the element. On the electric side, we provide a smart controller which is super easy to install. This smart controller will manage the system and can be controlled/monitored by your phone via your Wi-Fi.


To summarise, you will get the following:

3 x 440watt Black Photovoltaic solar panels

Black anodised aluminium mounting kit with L-Brackets for metal roofs

1 x Solar MPPT controller for hot water

    Shipping to Rural Areas

    Please note: all rural freight delivery addresses will attract a Rural Delivery surcharge.

    Our freight estimates on our website are to the registered freight company depot address, closest to the customer's delivery address, and to most metropolitan addresses. For rural area addresses, freight companies reserve the right to charge a surcharge where they deem necessary. In this case, if the original shipping fee charged is not sufficient to cover the Rural Delivery Surcharge to deliver to the customer’s provided address, your order will be delivered to the nearest freight company depot address. From that point, it’s the customer’s responsibility to arrange delivery at your cost. When your order is ready for collection depot staff will give you a call to let you know.

    If you are not able to collect it from the depot and require a door-to-door service, our staff member will contact you by email to let you know the extra fee for the Rural Surcharge needed for the freight company to deliver the package to your provided address.

    Oversized Items

    Any large, unusually-shaped, package over 1500mm, volume over 0.125m3, or heavy parcels over 25kg items within New Zealand might attract an oversize surcharge.
