Why choose us
Solar isn't about buying the cheapest system. It's about buying the right system.
An undersized or poorly matched system disappoints. A system designed around your real electricity requirements does the job it was bought to do.
Designed around your actual usage
We start with your electricity account, not a standard package off a price list.
Suitable equipment for the job
Panels, inverter and batteries chosen to match the load your property actually carries.
Installation workmanship
Neat cabling, secure mounting and tidy boards — the parts of a system you live with for years.
Room to grow
Where it makes sense, we design so that capacity can be added later.
40+ years of experience

How it works
Four steps from your bill to your installed solar system
Every property is different. Your system should be designed around your actual electricity requirements.
Send us your electricity bill
Your latest account tells us what you actually spend and how much electricity you use.
We assess your usage
We review your consumption, tariff and how your property uses electricity through the day.
We design a system for your property
Panel layout, inverter and battery capacity are matched to your requirements and your roof.
We install it
Our team installs and commissions the system and shows you how to work with it.
The central question
Could your electricity bill be paying for your solar system?
Money spent on electricity every month is money that is gone. The same monthly expenditure could instead go towards power infrastructure you own.
What that depends on
Whether the numbers work — and how long it takes — is different for every property. It depends on:
- Your electricity consumption
- Your tariff and future tariff increases
- System size and price
- How much electricity the system generates
- Whether batteries are included
- Finance costs and terms
- Your property and roof
- How and when you use electricity
Your solar system can keep producing after it is paid off
Electricity payments continue for as long as you buy electricity. A solar system, once it is paid off, is equipment you own that continues to produce electricity. That is the difference worth understanding before you decide.
This is an explanation of how solar finance can work, not a promise of a payback period. We do not quote a fixed number of months — the only honest answer comes from an assessment of your own usage.
Illustration
Same monthly expense. Different long-term outcome.
A simple illustration of two paths for the same monthly electricity expenditure.
Without solar
R8 000
per month on electricity today
- 1You pay your electricity account every month.
- 2Tariffs are adjusted upward over time.
- 3The amount you pay tends to rise.
- 4The money is spent permanently — nothing is owned at the end.
An ongoing expense with no end date.
With solar
R8 000
the same monthly energy expenditure
- 1Your monthly energy expenditure is split between solar finance and any remaining grid costs.
- 2The finance term runs for a fixed period.
- 3At the end of the term, the system is paid off.
- 4You own the equipment, and it keeps producing electricity.
An expense with an end date, and equipment you own.
The R8 000 figure is illustrative only. Actual numbers vary from property to property and depend on consumption, tariffs, system price and finance terms.
