Solar Savings by Day. Uninterrupted Power When Load Shedding Hits.
Combine a grid-tie solar system with an existing or new generator for the most cost-effective load shedding solution. Your business runs on solar during the day, and your generator only kicks in when Eskom fails — slashing both fuel costs and electricity bills.
Your Generator Is Expensive to Run. Solar Can Change That.
If you're already running a diesel generator during load shedding, you know the fuel bills add up fast. A generator integrated with grid-tie solar means your building runs on free solar power during daylight hours — and the generator only runs when Eskom is down and the sun isn't enough.
Diesel generators cost R8–R15/kWh to run — 5–10x more than solar
Most load shedding happens during daytime business hours when solar is generating
Solar drastically reduces generator run hours, cutting fuel and maintenance costs
No battery required — lower capital cost than a full hybrid system
How the Solar + Generator Combination Works
We design a system where your solar panels, existing grid supply, and generator work as a seamless energy source. Advanced transfer switches and inverters manage the changeover automatically — your staff never have to touch anything.
Reduction in daytime electricity costs from solar
Reduction in generator run hours
Transfer time — no power interruption
Typical payback including generator savings
How It Works
Solar panels generate power during business hours, reducing Eskom consumption
When load shedding starts, the system detects the Eskom outage automatically
Your generator starts and takes over within seconds
Solar and the generator work together — reducing fuel burn while load shedding
When Eskom returns, the system seamlessly switches back and stops the generator

Multiple Ways to Finance Your System
Most of our clients achieve positive cash flow from month one — the savings exceed the finance repayment.
Section 12B
The solar component qualifies for 100% tax deduction in year one.
Asset Finance
Finance both the solar system and generator together for a single monthly payment.
If you already own a generator, we integrate with it — you only finance the solar components.
Common Questions
Can you integrate with my existing generator?
In most cases yes. We'll assess your generator's capacity, condition, and control system. If it's compatible, we integrate — no need to replace it. If it's undersized or incompatible, we can supply and install a new unit.
What generator size do I need alongside solar?
This depends on your critical load and solar system size. A 140 kWp solar system paired with a 200 kVA generator typically covers most commercial operations fully. We'll size both correctly for your specific needs.
Is load shedding protection guaranteed?
As long as your generator has fuel and is in working order, yes — the system will keep your business running through any stage of load shedding. We recommend at least 8 hours of fuel storage for Stage 6 resilience.
Does this qualify for Section 12B?
The solar panels, inverters, and associated equipment qualify for the 100% Section 12B deduction. The generator itself doesn't qualify unless it's directly integrated as part of the solar hybrid system — consult your tax advisor.
