How much will it Cost to Install Solar Panels in South Africa

What size solar panel do I need?

There are numerous sizes of solar panels available. However, due to solar panel manufacturers producing larger panels, it would be best to buy 450W panels and up.

The average household uses between six and fourteen 455W solar panels and up to around twenty-three panels for bigger homes. But, it depends on the space you have available, your electricity usage and the parameters of your inverter.

How to calculate solar system size?

Find your average monthly usage in kW, divide that by 30 (days in the month) then divide that number by 5.5 (average peak sun hours per day in South Africa). This will give you the size of the array that you’ll need. Then you take your array size and divide that by the watt rating of a panel like a 455W panel to find out how many solar panels you’ll need.


  • 900kWh average monthly usage / 30 days = 30kWh daily usage
  • 30kWh / 5.5 average maximum production hours = 5454.54kWh array size needed
  • 5454.54kWh / 455W solar panel rating = 11.988 solar panels needed so round it up to 12.

How long do solar panels last?

Solar Panels can last 20 years and sometimes even up to 30 years. Ensuring that your system is in good health, you should see your solar equipment running smoothly well into the future.

How many panels in a 5kw solar system?

The number of panels you will need within a 5kW system is entirely dependent on the parameters of the inverter. You will first need to check what the maximum PV array input is and secondly, check the voltage ranges of the inverter. You do not want to exceed either of those 2 parameters.

Which direction should solar panels face in South Africa?

Your solar panels should be in the sun all day to be able to produce solar power. So north-facing is best in South Africa. However, if your roof is not north-facing, you can still produce solar power by installing two arrays, one on the east and one on the west-facing roof. That way your east-facing array will produce solar power in the morning and your west-facing roof will produce solar power in the afternoon. To do this, you will need a high voltage inverter with 2 MPPTs or 1 MPPT with a combiner box.

How Much Money Will a 5kw Solar System Save You Every Year?

For your typical residential home in Cape Town, electricity costs are 330c/kWh. We estimated earlier that your 5kW solar system would save you 6,000-8,000 kWh per year.

Multiplying the electricity cost with the energy saved shows that your investment cuts your annual electricity bill by R19,800 to R26,400.

This means you get a return on your investments after four (4) to six (6) years. With manufacturers issuing warranties that last up to 25 years, you are likely to begin saving money beyond your sixth year of ownership.

How Much Does a 5kw Solar System Cost in South Africa?

Okay, let’s do a quick recap: 5kW solar system. 20 polycrystalline panels. 45 m2 roof space. 6,000-8,000 kWh electric energy saved per year. Now, how much is this going to cost?

According to our research, a 4kW to 5kW system is going to cost you around R70,000-R140,000. We do not recommend that you do this independently. This is a big project, and plenty is at stake, especially your safety. However, we will give you an idea of how much the main components cost so you can negotiate with your supplier or contractor.

Solar Panel Prices

Solar Panel prices depend on brand and size.

Prices range between around R2500 for a 345W Monocrystalline Solar Panel and R4500 for a 540W Monocrystalline Solar Panel.

Solar Panel Installation Price
Solar panel installation costs vary from installer to installer.

However, you will usually pay a base cost for a Solar Power Kit installation which will include the hanging and wiring of your inverter and battery and the connection to your distribution board.

Then will be a per panel installation price.
If you need to install 12 solar panels, your installation cost will be higher than that of someone who only needs 6.
For a 6 panel installation, you can expect to pay upwards of R12,000.

Where to start

It is important to take on the services of a reputable installer that uses top-quality equipment. A sales representative visits your house to assess requirements and then provides a quote. The larger the house, the more the lighting and appliances, the bigger the system.

    Hi do you have a branch in johannesburg

  20. Robin Hayes says:

    I have received quotes for an inverter system 5kW with 2 x 5.5kWh lithium batteries of around R65 000. If I decided on solar panels from your example I would only need 2 panels – my monthly consumption is only 300kWh.
    My concern is the time it would take to recharge the batteries after a load-shedding incident of up to 4.6h.
    Your opinion, please.
