The 5 kW solar system in South Africa consists of solar panels, batteries, and an inverter. These components work together to harness and store renewable energy for use in powering homes or businesses.

Solar Panels

Solar panels are the heart of a 5 kW solar system. They capture sunlight and turn it into electricity for your home or business. In South Africa, you might need about four monocrystalline solar panels to make up this kind of system.

Each one can cost between R2500 and R4500, so the total for just the panels could be around R86,000. These panels are built to last and can save you money on your electricity bills by using the sun's power instead of fuel from the grid.

They work best in bright sunlight, but even on cloudy days, they still manage to grab some rays and keep energy flowing. With good care, these solar PV panels will help keep lights on and machines running at home without costing too much or harming our planet.

And when there's extra power made during sunny days, it can be stored in batteries or sent back to the electrical grid if your house is hooked up that way—clever stuff!


Batteries play a key role in your solar power system. They store the energy you collect from the sun. This way, you can use electricity whenever you need it, even when the sun goes down.

It's like having a savings account just for energy.

In South Africa, getting batteries for your setup might cost quite a bit at first. Usually, people choose lithium iron phosphate batteries because they last longer and are safer than other types.

Expect to pay between R115,000 and R120,000 for two batteries along with eight panels as part of a hybrid solution. Even though this seems expensive now, these batteries will help save money on power in the long run.


An inverter is a key part of your solar power system. It turns the direct current (DC) from your solar panels into alternating current (AC) for your home appliances. In South Africa, a typical 5kW solar setup comes with a 3.6kW inverter.

You can choose between different types, like string inverters, microinverters, or hybrid inverters.

Choosing the right type matters because it affects how well your system works. Hybrid inverters are popular as they allow battery storage to be used when there's no sun or during power outages.

They work with energy sources like grid power and can provide an uninterrupted power supply, which is handy during load shedding. Pick an inverter that matches what you need, whether it’s saving on bills or keeping lights on when the grid goes down.
