Complete systems
Collector and tank supplied and installed as one system, sized to how many people are in the house and how they use hot water.

Hot water andwater pressure.
The geyser is usually the biggest single item on an electricity bill, and a borehole on a grid pump is the second. Both of them can run off the sun instead — with a backup for the days it does not shine.

Heating water is the one thing the sun is genuinely good at. A solar geyser is a simpler machine than a solar power system — fewer parts, less to go wrong — and it takes the single hungriest load off your bill.
Retrofit to an existing geyser
Where the existing geyser is sound, a collector can often be added to it rather than replacing the whole thing. We check the geyser first and tell you which way is worth it.
- keep existing tank
- conversion
- assessed first
Electrical backup element
The element stays, as backup. On a run of cold, grey days you still get hot water — you just pay for it that week instead of every week.
- element retained
- timer
- no cold showers
Plumbing & pressure
Correct valves, vacuum breakers and drip trays, plumbed and pressure-tested before we leave, so the first thing you find out about is not a ceiling stain.
- valves
- drip tray
- pressure tested
Timers & controllers
Set up so the element only tops up when it needs to, rather than fighting the sun all afternoon and undoing the point of the system.
- timers
- thermostat
- element control
Servicing & repairs
Leaks, failed elements, tired valves and collectors that have stopped performing — including systems installed by someone else.

ch10 · power stackBorehole solar pumps
A borehole pump that runs on panels fills the tank in daylight and costs nothing to run. Gravity and a pressure pump do the rest, so the house has water at night without the pump having ever touched the grid.
Solar pump sizing
The pump is chosen for the depth of the hole, how much water it delivers and how high it has to lift — then the panels are sized to that, not the other way around.
- depth
- yield
- head height
Controllers
A controller between panels and pump so it starts cleanly in the morning, handles a passing cloud without stalling, and does not hammer the pump every time the light changes.
- soft start
- cloud handling
- protection
Tanks & float protection
Storage sized so a cloudy day is not a dry day, with float switches that stop the pump when the tank is full and when the borehole runs low.
- storage
- float switch
- dry-run protection
Pressure pumps
The tank feeds a pressure pump so taps and showers behave like municipal water instead of trickling when someone opens a second tap.
- constant pressure
- tank to house
- sized to taps
Converting a grid pump
Already have a borehole on the municipal supply? In many cases the pump can be moved onto solar. We check the pump, the depth and the yield before promising anything.
- existing borehole
- assessed first
- changeover
Yards, gardens & farms
Irrigation, stock water and garden supply from the same system, sized for what the borehole can actually sustain rather than what you would like it to.
- irrigation
- stock water
- sustainable yield

before we quote
helps · not requiredWhat we need to know
Borehole details are the ones people usually have to look up — if you have the drilling report or the pump paperwork, send a photo of it.
- How many people in the houseAnd whether showers or baths are the norm. That sizes the hot water.
- Your current geyserSize in litres, roughly how old, and where it sits — roof space or outside wall.
- Roof access & typeWhether a collector can be mounted and which way that roof faces.
- Borehole depth & water levelFrom the drilling report if you have it. A rough figure is better than nothing.
- What the borehole must supplyHouse only, or garden, irrigation and stock as well.
- Existing pump & tankMake and size if you know it, and whether it currently runs on the grid.
Do not have all of that? Message us anyway. The survey exists precisely so that you do not have to work any of this out yourself — it is free, and there is no obligation at the end of it.

Questions
Yes. The electrical backup element stays in the geyser, so on a run of grey days the system tops up from the grid exactly as your geyser does now. The difference is that on every other day it does not.
Often. If the tank is sound and correctly positioned, a collector can be added to it rather than replacing the whole geyser. We look at the geyser before quoting and tell you honestly whether converting or replacing is the better spend.
That depends on the pump, and the pump depends on your borehole — depth, standing water level and how much the hole yields. Send us the drilling report or the details of the existing pump and we will size it properly.
Usually not. It runs directly off the panels during daylight and fills a tank, and the tank is what carries you through the night. That keeps the system simple and cheap to maintain.
A float or level switch in the borehole, plus dry-run protection in the controller. It is standard on our installs — a pump that runs dry is a pump you replace.
Yes — tank, stand, float and the plumbing between them can all go on the same quote. Tell us where the tank can stand and how much storage you want.
Not directly, but the tank can. The pump fills the tank in daylight and a pressure pump feeds the house from the tank around the clock.
