— OFF-GRID
Off Grid Living: A Practical Guide for South Africans
TL;DR
- Going off grid is a sequence, not a shopping spree — water first, then sanitation, then power.
- A workable South African off-grid setup costs roughly R150,000–R500,000+, depending on how much comfort you keep.
- It is a trainable set of skills, not a survivalist personality — competence beats kit every time.

Going off grid is not about bunkers, gold coins or escaping society — and most of what you have read about it online is wrong. It is a calm, practical project: detaching your home from the municipal services you have stopped trusting, and replacing them with systems you understand and maintain yourself.
I have lived off-grid on a Karoo-edge smallholding for over a decade. In that time I have learned that the romance fades fast and the engineering stays. The people who thrive are not the loudest preppers; they are the ones who sequence things sensibly and fix problems before sunset.
This guide gives you that sequence, real ZAR numbers, and the honest trade-offs. Less fear, more competence.
What does off grid actually mean?
Off grid means your home does not depend on municipal electricity, and often not on municipal water or sewerage either. You generate, store and treat your own essentials.
There is a spectrum here, and pretending otherwise causes most of the disappointment I see. Full off-grid living means zero connection to Eskom and the council. Partial off-grid — sometimes called “grid-tied with backup” — keeps a connection but relies on your own systems day-to-day. Many South Africans who semigrate to the Western or Eastern Cape start partial and move closer to fully independent over a few years.
Three pillars define every off-grid home:
- Water — borehole, rainwater harvesting, or both, with storage and treatment.
- Sanitation — septic, composting toilet, or a worm farm system.
- Power — usually solar PV with battery storage, sometimes a generator for backup.
Notice what is not on the list: tactical gear. Off-grid resilience is a trainable skill, not a personality trait.
In what order should you go off grid?
Go in this order: water, then sanitation, then power. People do it backwards — buying a flashy solar system while still trucking in drinking water — and then wonder why life feels precarious.
The logic is simple. You can live for weeks in candlelight, but only days without safe water and clean sanitation. Yet load-shedding has made everyone reach for solar first. That impulse is understandable; it is also the wrong sequence.
| Priority | System | Why it comes first | Typical ZAR range |
|---|---|---|---|
| 1 | Water supply & storage | Non-negotiable for life and hygiene | R20,000–R120,000 |
| 2 | Sanitation | Prevents disease; cheap to get right early | R8,000–R60,000 |
| 3 | Power (solar + battery) | Improves comfort and runs pumps | R80,000–R350,000 |
| 4 | Food production | Reduces dependence over time | R5,000–R40,000 |
If you only remember one thing from this article, remember the order. Sequencing is what separates a calm off-grid home from an expensive, half-finished one. For more on prioritising, see our guide to water storage for South African homes.
Sorting water: boreholes, JoJo tanks and rain
Secure your water before anything else. In South Africa that usually means a borehole, rainwater harvesting into JoJo tanks, or — ideally — both, with a simple treatment step before you drink.
A borehole gives you independence from failing municipal supply, but it is not free water. You need a geohydrologist or experienced driller, a pump (solar pumps have become excellent value), and a permit in some municipalities. Yields vary wildly across the country, so test before you build your whole plan around it.
Rainwater is the underrated hero. A roof of 100m² can capture around 8,000 litres from just 100mm of rain. Pair that with a few 5,000-litre JoJo tanks and you have a buffer that costs little and asks nothing of Eskom.
Treating your water
Stored and borehole water is not automatically safe. Per World Health Organization guidance (2023), microbial contamination is the chief health risk. My standard set-up: sediment filter, then a carbon filter, then either UV treatment or simple boiling for drinking water. It is cheap, proven, and removes the guesswork.
Off-grid power without the load-shedding panic
Off-grid power in South Africa is almost always solar PV with battery storage. Years of load-shedding have made it mainstream, dropped prices, and produced a glut of installers — some excellent, some not.
The honest order of operations is: reduce demand first, then size the system. Swap to gas for cooking and a heat-pump or solar geyser for hot water, and your electrical load can halve. A smaller, cheaper system then does the same job. Gear-worship sells big inverters; competence sells the right-sized one.
A typical off-grid home setup includes:
- Solar panels — 4–8kWp for an average home.
- Battery storage — 10–20kWh of lithium (LiFePO4) for overnight and cloudy days.
- Inverter — sized to your peak load, not your fantasies.
- Backup generator — optional, for winter or extended cloud.
South African solar yields are genuinely excellent — much of the country receives over 2,500 hours of sunshine a year, among the highest globally per SANEDI. That is your unfair advantage. Use it. For wiring and safety, always use a registered installer who issues a Certificate of Compliance.

What does off grid living cost in South Africa?
A functional off-grid home costs roughly R150,000 to R500,000+ to set up, depending on how much modern comfort you want to keep. The biggest variable is power; the cheapest wins are in water and behaviour.
Here is a realistic mid-range build, for a small household keeping fridges, lights, and basic appliances:
| Component | Modest setup (ZAR) | Comfortable setup (ZAR) |
|---|---|---|
| Borehole + solar pump | R45,000 | R90,000 |
| Rainwater tanks (3× 5,000L) | R18,000 | R30,000 |
| Water filtration + UV | R6,000 | R15,000 |
| Septic / composting toilet | R12,000 | R45,000 |
| Solar PV + battery + inverter | R95,000 | R280,000 |
| Vegetable garden setup | R8,000 | R25,000 |
| Total | ~R184,000 | ~R485,000 |
Two things keep costs sane. First, phase it — buy water systems this year, power next year. Second, reduce your demand before you buy capacity to meet it. The running costs afterwards are remarkably low: no monthly electricity bill, minimal water cost, and maintenance you can largely do yourself once you learn it.
Common off-grid mistakes to avoid
The biggest off-grid mistakes are buying before planning, oversizing power, and neglecting sanitation. None of them are about danger — they are about wasted money and avoidable stress.
- Buying power before water. A solar array means nothing if you are still hauling drinking water.
- Oversizing the solar system. Reduce demand first; you will spend far less.
- Ignoring sanitation. A poorly placed septic system or untreated greywater near your borehole is a real health risk.
- No food plan. Off-grid without a vegetable garden is just an expensive house. Start small — a few beds beat a grand permaculture plan you never finish.
- Treating it as an event, not a skill. Off-grid competence builds month by month. The boring maintenance is the whole game.
I have made versions of every one of these. The fixes were never dramatic — they were patient, sequenced, and cheaper than the original mistake. That is the quiet truth of self-reliance: it rewards calm planning far more than urgency.
Key takeaways
- Off grid means independence from municipal power, water and sewerage — on a spectrum, not all-or-nothing.
- Sequence it: water first, then sanitation, then power, then food.
- South Africa’s abundant sunshine makes solar a genuine advantage — but reduce your demand before you size the system.
- Budget R150,000–R500,000+, and phase the spend across years rather than panic-buying.
- Always treat stored and borehole water before drinking; this is the cheapest, highest-value safety step.
- Off-grid resilience is a trainable skill, built through maintenance and small wins — not gear.
Frequently asked questions
Is off grid living legal in South Africa?
Yes, off grid living is legal in South Africa. You can disconnect from the grid, drill a borehole (with the relevant municipal authorisation in some areas), and install solar power. Solar electrical work must be certified by a registered installer, and boreholes may require registration with your local authority. Always check your specific municipal by-laws before you start.
How much does it cost to go off grid in South Africa?
A functional off-grid home typically costs between R150,000 and R500,000 to set up. Power is the largest expense, while water harvesting and behaviour changes offer the cheapest wins. Phasing the project over two or three years spreads the cost and lets you learn each system before adding the next.
Can I go off grid with just solar power?
Solar alone solves electricity, but it does not make you off grid. True independence also requires secure water and sanitation. Many people install solar first because of load-shedding, then realise they still depend on municipal water. Sort water and sanitation alongside power for genuine self-reliance.
How much land do I need to live off grid?
You can live off grid on as little as 1,000m² if you focus on power and water rather than full food self-sufficiency. Growing most of your own food comfortably needs roughly half a hectare to a hectare, depending on climate, rainfall and how much you eat from your own garden versus the shops.
Is off grid living safe and reliable?
Yes, when systems are sized correctly and maintained. Modern lithium batteries, quality filtration and properly drilled boreholes are reliable for years. The main risk is human, not technical: neglecting maintenance or skipping water treatment. Treat off-grid living as an ongoing skill, and it becomes calmer and more dependable than relying on failing municipal services.
