Off-Grid Solar Systems for Homes & Businesses
Complete energy independence — no Eskom connection, no monthly electricity bill, and no exposure to load shedding, tariff increases, or grid failures ever again.
Some properties don’t have the luxury of waiting for Eskom
Whether you’re building on a plot far from the nearest substation, running a farm with an unreliable supply, or simply done with the rising cost and unpredictability of grid power — an off-grid solar system gives you complete, self-sufficient energy independence.
Your solar panels generate power during the day, your batteries store what you don’t use immediately, and your home or business runs entirely on its own. As a result, there is no grid connection, no monthly bill, and no surprises.
Off-Grid Solar Power: How It Works
Off-grid solar systems operates entirely independently of the municipal electricity grid. Solar panels generate power during daylight hours, charging a battery bank that supplies your home or business around the clock. A charge controller manages the flow between panels, batteries, and loads, while an off-grid inverter converts stored DC power into the AC power your appliances use.
Correctly sized, an off-grid system is designed to meet your full energy demand — day and night, summer and winter.
The result:
- Zero monthly electricity bill
- Full protection from load shedding, grid failures, and tariff increases
- Viable power supply for remote or rural properties with no grid access
- Long-term energy security with predictable, fixed costs
Is an Off-Grid System Right for You?
Off-grid solar is the right choice where grid connection is unavailable, prohibitively expensive, or simply no longer worth the ongoing cost.
Remote & Rural Properties
Farms, smallholdings, and plots where extending the grid is expensive or impractical. An off-grid system is often more cost-effective than a new Eskom connection over any meaningful distance.
Homeowners Seeking Full Independence
Homeowners who want to cut ties with Eskom entirely — done with tariff increases, load shedding schedules, and the uncertainty of municipal supply.
Farms & Agricultural Operations
Irrigation pumps, cold storage, processing equipment, and staff accommodation all running independently of an increasingly unreliable grid.
Lodges, Cabins & Eco Retreats
Remote hospitality properties where a reliable, self-sufficient power supply is essential to the guest experience — and where a grid connection may never have been an option.
How it works
1
Site Assessment
We assess your property’s energy demand, location, roof or ground-mount options, and seasonal sun exposure. For off-grid systems, accurate sizing is everything — we take the time to get it right.
2
System Design
Your system is then designed around your specific energy requirements, including the solar array, battery bank, charge controller, and inverter. Every component is correctly sized to meet demand through day and night, and throughout the lower-generation winter months.
3
Installation
Professional installation by certified solar installers. Panels, off-grid inverter, battery bank, wiring, and full commissioning — all carried out to SANS standards, with no detail left to chance.
4
Support & Maintenance
Once installation is complete, we commission the system with live monitoring and provide full handover training so you understand exactly how it operates. Ongoing servicing, battery health checks, and system optimisation keep your supply reliable for the long term.

“
For more than 8 years, my family and I have lived completely off-grid on our farm in Keurbooms, Plettenberg Bay, powered entirely by solar energy and harvested rainwater — with no Eskom and no municipal water.
During that time, we have built and connected four homes to a single off-grid system. Three of these homes are very busy Airbnb rentals, providing ongoing real-world testing of the system under varying occupancy and demand.
Living this way every day has given me firsthand insight into what truly works. The solar and water solutions I recommend are based on years of practical experience and a deep understanding of what it takes to achieve reliable, long-term independence.

Frequently Asked Questions
Off-grid systems typically range from R150,000–R400,000 or more, depending on your energy demand, battery capacity, and property requirements. The absence of an ongoing electricity bill means the investment pays back over time — and for remote properties, it is often cheaper than a new Eskom grid connection.
An off-grid system operates with no grid connection at all — your property runs entirely on solar and battery power. A hybrid system stays connected to the grid and uses batteries for backup, with Eskom as a safety net. Off-grid suits remote properties or those wanting full independence; hybrid suits suburban homes wanting load shedding protection.
We design off-grid systems to account for seasonal variation and extended low-generation periods. Battery bank sizing, system capacity, and where necessary a backup generator input are all factored into the design to ensure your supply remains reliable year-round.
Battery lifespan depends on the technology specified and how the system is managed. Quality lithium battery banks typically last 8–15 years with proper maintenance. We specify batteries suited to your usage profile and provide guidance on best practices to maximise their lifespan.
In most cases, yes — provided the system is correctly sized. High-consumption appliances require a larger solar array and battery bank, which affects cost. During the design phase we work through your full load list and help you make informed decisions about what to power directly from solar versus more efficient alternatives.
We design and install off-grid solar systems in Plettenberg Bay, Knysna, George, Wilderness, Sedgefield, and on farms and rural properties throughout the Garden Route and beyond.
Expansion is usually straightforward when the system is designed with future growth in mind. Additional panels, extra battery capacity, or increased inverter capability can be added as your energy needs grow or your budget allows.
