Cut Your Electricity Bill by 40–60% — Starting Month One
Grid-tie solar is the fastest-payback commercial solar option available. Your panels generate power during the day, your building uses it first, and anything unused feeds back to Eskom — spinning your meter backwards.
Eskom Tariffs Are Rising Faster Than Inflation
The average commercial Eskom tariff has increased over 12% per year for the last decade. Your electricity bill this year is already 12% higher than last year — and next year will be worse. Grid-tie solar breaks that cycle permanently.
Commercial electricity now costs R2.50–R3.50/kWh on Eskom tariffs
Solar generation costs as little as R0.60–R0.80/kWh over the system lifetime
Section 12B tax incentive lets you write off 100% of the system cost in year one
No batteries means lower capital cost and faster break-even
How Grid-Tie Solar Works for Your Business
We install solar panels on your roof or carport. A grid-tied inverter converts the DC power to AC and feeds it directly into your building's distribution board. Your business consumes solar power first — reducing what you buy from Eskom in real time.

How It Works
Solar panels on your roof capture sunlight during business hours
Grid-tied inverter converts DC to AC and synchronises with Eskom supply
Your building uses solar power first — Eskom only tops up the difference
During load shedding, the system safely shuts down (add a battery to stay on)
Smart monitoring lets you track generation and savings in real time

Asset Finance
Spread payments over 3–5 years with a bank or specialist solar financier. Many clients achieve positive cash flow from month one.
Cash Purchase
Highest ROI over the system lifetime. Typical payback 3–5 years on a 25-year asset.
Common Questions
Does grid-tie solar work during load shedding?
No — standard grid-tie inverters shut down when Eskom supply is lost, for safety reasons. If load shedding resilience is critical, we recommend adding a battery or generator integration. We can design a hybrid system from the start.
How large a system do I need?
We size systems based on your actual electricity bills and consumption profile. A 100 kWp system typically generates 130,000–150,000 kWh per year in Gauteng and suits businesses spending R40,000–R80,000/month on electricity.
What happens to surplus generation?
Surplus power can feed back to Eskom under net-metering (if your municipality allows it) or simply reduce your import. We'll advise on the best approach for your tariff and local utility.
How long does installation take?
A typical 100–200 kWp commercial installation takes 2–4 weeks from council approval. We handle all permitting, COC certificates, and Eskom/municipality grid-connection paperwork.
What maintenance is required?
Very little. We recommend an annual inspection and panel cleaning. We offer maintenance contracts that include monitoring, cleaning, and inverter health checks.
