When load-shedding hits, South Africans reach for one of two solutions: a generator or a solar and battery system. Both keep the power on, but they are very different investments. Here is how they compare.

Running Costs

A generator needs petrol or diesel every time it runs — an ongoing cost that rises with fuel prices. Solar runs on free sunlight and stored battery power, so after the initial purchase your running cost is close to zero.

Noise and Convenience

Generators are loud, produce fumes and must be started and refuelled. A solar system is silent, automatic and switches over instantly when the grid fails — you often will not even notice load-shedding has started.

Long-Term Value

A generator only costs you money. Solar cuts your daily electricity bill as well as providing backup, so it pays you back over time and adds value to your property.

When a Generator Still Makes Sense

For very large, occasional loads a generator can play a role, but for everyday load-shedding backup in a home or small business, solar is cleaner, quieter and cheaper to run. Many customers who start with a generator switch to solar within a year.
